Mice were divided into three groups (five mice for each group), taking into consideration body weight, liver and kidney weights. T1 : receiving the toxin once and sacrificed after two days. T2 : given the toxin twice for one week. T3 : given the toxin twice a week for two weeks. Each treated group has its corresponding control which received 1% Dimethyl Sulphoxide (DMSO). The results showed the histological changes in liver tissue in T2 and T3 groups which represented by congestion vascular with necrosis and degeneration in hepatic cells in addition to reduction in glycoprotein granules. While, the histological changes in kidney tissue included congestion vascular and degeneration in distal and proximal tubules. No obvious histological changes were noticed in liver and kidney tissues in T1 group.The results of biochemical tests for kidney and liver enzymes AST (Aspartate Aminotransferase) , ALT (Alanine Aminotransferase) were shown no significant differences in means of the specific activity of these enzymes , AST and ALT in T1 and T2 groups .In contrast T3 group showed significant decreasing in values for both enzymes AST and ALT (14.00 , 12.33) IU/ L respectively . ALP (Alkaline Phosphatase) enzyme was increased significantly in T2 and T3 groups (23.00, 18.00) IU/L respectively compared with T1 and control groups . The results of Creatinine concentration in kidney tissue revealed no significant differences in all groups. In regard to Urea concentration in kidney tissue was decreased significantly in T2 and T3 groups (24.83,23.66) mg / L respectively compared with the rest of groups. The other part of the present study was to investigate the biological degradation of Zearalenone using by Iraqi probiotic 2% (w/v) and yeast filtrate of Saccharomyces boulardii which had an active influence . As observed a clear improvement in liver and kidney tissues for group of mice that fed contaminated diet by F. graminearum produced Zearalenone with Iraqi probiotic and yeast filtrate compared with positive control ( group of mice fed contaminated diet by F. graminearum produced Zearalenone ) that caused the histological changes in liver and kidney tissues .The results of liver enzymes showed significant differences in positive group for three enzymes ALS , ALT and ALP reached ( 15.66, 14.66, 25.66 ) IU/ L respectively , compared with negative control (group of mice did not fed contaminated diet by F. graminearum produced Zearalenone ). However , the results of the interaction between mice fed contaminated diet by F. graminearum produced Zearalenone with Iraqi probiotic and yeast filtrate were shown significant increasing for ALS , ALT , ALP enzymes in addition to urea concentrations in kidney tissue compared with positive control

Abstract: This study aimed to detect the fungal contamination of hospitals in orderto be controlled and limited.A total of 511 environmental swaps were collected from Al - Karamateaching hospital, Al - Sader general hospital, Al - Yarmouk teachinghospital, Baghdad teaching hospital and Imam Ali general hospital inBaghdad city from the period 28,October,2013 to 31,March,2014. Thesamples were collected to isolate and identify the caused and contaminatedfungi in addition to test their sensitivity against certain antiseptic anddisinfectants that are used in hospitals; also their virulence factors forhigher frequency and occurrence genus.These isolates were collected from main sources, the hospitalsenvironment and most of the items used for hospital work in order to detectthe nosocomial pathogens persistent in the hospital ecosystem, whichincludes : sink surfaces, tools and equipments, walls, indwelling medicaldevices, premature incubators, beds, medical trashes, floors and others.Results revealed that fungal contamination in five hospitals was in thepercentage 69.89%, 64.52%, 62.40%, 51.58% and 41.90% respectively. Inaddition, the most contaminated places were the hospitals wards 80%,while it was 77.77% in endoscopy units and 76.92% in the Respiratory careunits. The lowest contaminated places were the emergency units 25.0%then burns units 33.33% and cardiac care unit which was 41.66%. Inrespect with the percentage of occurrence and frequency for the isolatedfungi, it was found out that Aspergillus flavus formed the highest ratio offrequency and occurrence 21.29% and 15.46% respectively, followed byAspergillus niger 18.33% and 13.31% then Penecillium spp. which was10.78% and 7.83%. Regarding other fungi, their frequency and occurrence were different. All fungal isolates were identified depending on themorphological and microscopic examinations as well as biochemical tests.The results on the effect of temperature and pH on fungal growthshowed that the best growth was at 25 - 30 OC, and the best growth wasfound at the pH range 5.0 - 6.0.Results of the test of fungal sensitivity against eight antiseptics andsterilizers used in the hospital showed that the ratio of inhibition of thesecompounds agnaist fungi were different according to types andconcentration of antiseptics as well as genus and species of fungi. Use ofthese compounds in 100%, 50%, 40%, 30% and 20% concentration is veryhigher effective, while more effective if they were used in 10% or 7.5%concentration than in 5% and 2.5%, but not effective in 1.25%concentration.The results showed that Setol (Chloroxylenol) has significantly the mosteffective compound on fungi, followed by Formalin (Formaldehyde), thenCarmal (Tension, active surfactants, non - ionic) and Alwazir (Sodiumhipochlorite).Testing some of virulence factors aflatoxin production, lipaseproduction , protease production and haemolysis test, it was found that A.flavus has higher lipase production and protease production than otherfungi. A. flavus and A. niger were capable of blood hemolysis in 3 daysonly, but in different diameters of lysis zone, 1.8mm and 1.6mmrespectively. Some isolates of A. flavus are capable to aflatoxin production.Depending on all results, hospitals contain different fungal species andgenus, antiseptics and disinfectants have an effect on fungal growth if theyare used in a correctly.

1) مايكروغرام\مل وكانت جميع C. albicans التي تم عزلها حساسة تجاه الاتراكونازول واظهرت خمائر الCandida الاخرى non - albicans Candida استجابة اقل نسبيا مع الحاجة الى تراكيز دوائية اعلى من اجل التوصل الى MIC وان 96.2 % من الCandida التي تم عزلها استجابت الى الاتراكونازول وان الباقي اي 30.8% كانت تستجيب حسب الجرعة. | Through the period of this study which extended from November 2003 to April 2004, 300 patients with different types of malignancies were tested for fungemia. Out of those, 17 patients showed positive blood culture results. Candida albicans accounted for the majority of fungal infections. Out of the 17 fungal isolates, 9 (53%) were C. albicans, others non C. albicans came next in frequency constituting 4 isolates (23.5%). Two isolates of Aspergillus spp. could be detected while a single isolate of Cryptococcus spp and another of Trichosporon spp. isolate were cultured API system (API Candida and API 20C AUX) was used as a reference method for the identification of isolates. Compared with the other newly introduced techniques (ID 32C systems and VITEK YBC). ), the API 20C and the ID 32 system were in agreement with the species level, without additional tests, for the identification of 13 of the 15 (86.6%) isolates.Overall, the updated Vitek YBC compares favorably with the API 20C in the identification of common yeasts. Among the 300 patients whose blood were cultured, 71 of them were screened for fungal infection from other parts of the body. Urine was the commonest sample obtained. However, two samples only out of the total (35 samples) were accepted to be culture positive. Among the 17 patients whose blood cultures proof the existence of fungi, 8 were colonized with the same species in other specimens. The most frequent sites of colonization with the same organism were the respiratory tract and urogenital tract.The mean of neutrophils count of the blood culture positive samples was 1136/c.mm with a standard deviation (SD) of 1637, whereas the mean count of culture negative cases was 2701 with a SD of 1923. Mean count of healthy control group was 5027 with a SD of 1667. Statistical analysis showed significant differences between the study groups. Using commercially available Candida - specific antibody test (Bio - Rad), 25 patients showed positive results out of the 300 patients tested. Nine of them showed positive blood culture as well, whereas the rest (16) gave negative culture results. None of the healthy control group showed positive results. Mean OD readings of the blood culture positive samples was 1.11 with a SD of 0.68, whereas the mean OD readings of the culture negative cases was 0.43 with a SD of 0.23. Mean OD readings of healthy control group was 0.38 with a SD of 0.123. Interleukins (ILs) concentration tested in this study showed significant variations among the different groups of the study as well as within the same group. Mean concentration of IL - 1α in the blood culture positive samples was 30.94 pg/ml with a SD of 80.33, whereas the mean concentration of the culture negative cases was 16.08 pg/ml with a SD of 28.75. Mean concentration of healthy control group was 7.92 pg/ml with a SD of 3.26. Mean concentration of IL - 8 in the blood culture positive samples was 389.2 pg/ml with a SD of 383.l5, whereas the mean concentration of culture negative cases was 163.0 pg/ml with a SD of 289.9. Mean concentration of healthy control group was 5.02 pg/ml with a SD of 1.81. Mean concentration of Granulocyte Macrophage - Colony Stimulating Factor (GM - CSF) in the blood culture positive samples was 12.90 pg/ml with a SD of 31.79, whereas the mean concentration of culture negative cases was 2.68 pg/ml with a SD of 10.19. The mean concentration of healthy control group was 0.85 pg/ml with a SD of 0.45. Serum immunoglobulins level showed no significant differences among the groups of the study whether IgG, IgM or IgA were tested. Mean level of C3 complement component showed significant differences between the groups of the study, being lower in culture positive group, and followed by culture negative group. However, no significant differences were noted in the groups in regard to C4. Level of CRP in different groups of the study shows significant variations (p=0.001). Moreover, variations are clear between individuals within the group itself. Approximate mean of CRP level in blood culture positive samples was 261.9 mg/L with a SD of 384.4 and, in blood culture negative samples was 178.8 mg/L with a SD of 346.2 and in healthy control group was 1.7 mg/L with SD of 7.7. CRP level in 58.8% of cases in culture positive group exceeded 96 mg/L. while only 37.4% of cases in culture negative group exceeded this value. Non in the control group exceeded this figure. All the tested isolates were susceptible to amphotericin B, with MICs ≤ 1ug/ml with the exception of a single isolate of C. krusei which was less susceptible than any other spp with MIC of 2 ug/ml and MIC50 of 2. The range of MICs to amphotericin B was from 0.125 to 2 ug/ml. In general, non - albicans Candida showed higher MIC than C. albicans isolates. A total of 84.6% of Candida isolates were susceptible to amphotericin while 15.4% were sensitive dose - dependant. The range of MICs to fluconazole was from 0.25 to 64 ug/ml. All isolates were highly sensitive to fluconazole with the exception of C. krusei which showed a high MIC (32) and MIC50 and MIC90 of 16 and 32 ug/ml respectively. A total of 84.6% of Candida isolates were susceptible to fluconazole while 15.4% were sensitive dose - dependant. The range of MICs to itraconazole was from 0.015 to 1.0 ug/ml. Most C. albicans isolates were sensitive to itraconazole. Non - albicans Candida showed relatively lower susceptibility with the need for higher drug concentrations to attain the MIC. 69.2% of Candida isolates were susceptible to itraconazole while the rest (30.8%) were susceptible in a dose - dependant way.

Soil samples are collected from different regions included agricultural, non - agricultural, salty, sandy and carbonate soil, purified 200 fungal isolates randomly and tested the antagonism with a number of pathogenic microorganisms . The 200 fungal isolates are tested by primary screening method to determine their ability to inhibit in vitro Pathogenic gram positive and negative bacteria and pathogenic fungi. The primary screening illustrate that 72 isolate were able to inhibition 3≤ pathogenic organisms. These isolates were tested to determine the acid productivity which found that only 13 were non - acid production and 59 isolate are product in different concentration. The acids producing isolates are excluded from the study because the rate of acid led to killing of test pathogenic microorganism .The selected isolates are non - acid productive and most effective in the inhibition of test pathogenic microorganism with a wide range. The samples are morphologically identified using the electron microscope and different diagnostic agricultural media (PDA, CYA, MEA), either molecular diagnosis of isolates have been using ITS1 and, ITS4 primer to amplify the Internal transcribed spacer region, the morphological and molecular identification results of the isolates showed that it belongs to Aspergillus fumigatus and Trichoderma longibrachiatum. The sensitivity results illustrate that the isolates 104 and S4 are the strongest in the production on potatoes peals solid media in compared with liquid residues media under the optimal production condition including temperature, hydrogen power and time of production. Results show that the isolated antimicrobial compounds were broad - spectrum against both G+ve and G - ve bacteria so it has been tested its effectiveness against a group of pathogenic yeasts and molds isolated from laboratories of Babylon hospitals.When comparing the results obtained with the results of pharmaceutical antibiotics found that the effect of the product exceeds the effect of Tetracycline, Amikacin, Ampicillin, Gentamycin, in addition to significantly impact on a range of pathogenic molds. The highest inhibition zone is obtained due to the isolation of S4 against the bacteria Bacillus seraus with diameter 43.35mm after the incubation the isolates on the potato peals solid media for 9 days at a temperature of 30 ◦C. These diameter is higher than the inhibition zone of Meropenem antibiotics against the same bacteria.Other aspects of this study include an extracted of the active compounds from the fermentation media using ethyl acetate and distilled water and then purifying the compound using thin layer chromatography(TLC) technique. Also it has been diagnosed the active compounds using the following chemical analysis (FTIR, HNMR and CHNS) to illustrated the type of effective compound.

In addition that, the highest ratio of the positive results was recorded in the ages of 61 - 70 years, followed by 31 - 40 years which were 32.94% and 15.25%, respectively. Totally, 106 isolates of the isolated opportunistic fungi appeared from the positive specimens. Through using morphological methods and molecular techniques, this study showed the first rank of the isolated fungi was Candida spp followed by Aspergillus spp, and Penicillium spp which possessed ratios of 49.41%, 38.32% and 21.17, respectively. According to the species, the first ratio of the isolation was Candida albicans followed by Aspergillus falvus, as 36.47%, 12.94%, respectively. Fifteen fungal isolates of the present study were recorded in the Gene Bank of NCBI. In this study, the extracts of Allium sativum were separately obtained by using four organic solvents (ethanol, acetone, methanol and water) and three concentrations (50%, 70% and absolute) of each solvents except water. Four concentrations of each extract were tested against 11 species of the isolated fungi in which the water extract gave the best value of the bioactivity including highest inhibitory value (60 mm) against Penicillium notatum by using 400µg\ml compared with the extracts of ethanol, acetone, and methanol. The bioactivity of Allium sativum extracts of each solvent was done against the tested fungi in comparison with Amphotericin B, Nystatin and Miconazole in which two of them produced the different bioactivities while Miconazole had no effect. The blood cytotoxicity of the crude water extract was performed against red blood cells and it did not appear any hemolysis. The chemical tests and Gas Chromatography (GC) revealed that the water extract contains alkaloids, phenols, flavonoids, terpenoids, tannins and carotenes in addition to sulfur formations, such as allicin as well as aromatic compounds.

Abstract: with the interest of medical and pharmaceutical uses of the natural products from marine fungi , thirty species of fungi belong to ninteen genus were isolated and identified from sea coast sediment of Al - Faw and Al - Seeba .The fungi Acremonium strictium , Geotricum candidum, Fusarium solani ,F.oxysporum , Penicilium sp. ,Trichoderma harzianum exhibited high inhibition activity toward growth of two reference strains of bacteria Escherichia coli (ATCC25922) and Staphylococcus aureus (NCtC 6571). The six selected fungi were grown in liquid culture media PDB at 25°C for two weeks ethyl acetate was used to extract the active compounds from thefermentation liquid media while ethanol was used to extract the active compounds from fungal mycelia .The crud extracts (fermentation and mycelium ) showed different inhibition activity against the pathogenic bacteria , Proteus mirabilis , S. aureus, isolates E. coli, Pseudomonas aeruginosa Klebsella pneumoniae. and pathoginic yeastes Candida albicans, C.tropicals,Cryptococcus neoformans and dermatophytic fungi Trichophyton verrucosum and Microsporium canis . The results revealed that the fermental fungi extracts has more inhibition activity than mycelial fungal extracts.The minimal inhibitory concentration (MIC) of fungal crude extracts were determined against gram positive and gram negative bacteria and pathogenic yeasts and fungi . antagonisum between studied fungi were evaluated , and the fungus T.harzianum has been the more antagonistic effect against other fungi. The toxicity of the fungal crude extracts were tested by using of human RBC at different concentration the result of this experiment showed that all extracts are non toxic except F.oxysporum extract.From all the above results the both F.solni and T.harzianum extracts showed higher activities ,thus these two extracts chosen for further studies. The anticancer activity of both extracts were studied against Hela cell line and the anticancer activity appeared at 250 Mg/ml and 62.5Mg/ml respectivily. The antioxidant activity of extracts were examined by three different methods ,B - carotene ,hydrogen peroxide scavenger and ferrus ion reduction , the results of three methods showed that both fungal extracts have antioxidant behaviours and the T.harzianum extract had more antioxident activity than F.solani extract and the antioxidant activity of both fungal extracts were increased as the concentration of the extracts increase.An optimization of the fungal growth and bioactivity of both fungi were conducted, by using different Nitrogen sources ( Asparagine , Yeast extract , peptone , Ammonium chloride , Sodium nitrate , Ammonium sulphate ) and carbon sources ( Maltose , Galactose , Glucose , Dextrose , Sucrose ,xylose and Starch ) the results elucidated that yeast extract was the best for growth of both fungi on solid and liquid media and high inhibition activity appear with T.harzianum against bacteria isolates , the carbon source starchenriched the growth of F.solani with more activity in inhibition the bacterial growth while the sucrose give high enrichment to the growth of T.harzianum in solid and liquid media with high activity toward bacterial growth. The study also indicates that the beast temperature and pH which gives the higher activity and growth 25°C and pH6 . The effect of different concentration of salinity were studied as well (1%,2%,3%,4%,5%,6% NaCl)and 2% showed the best concentration .The activity of two studied fungal extracts were superior than commercial antibiotic toward bacterial isolates .Preliminary qualitative chemical tests were carried out on the extracts and their chemical nature were identified .TLC technique were used and the chemical analysis showed that F.solani extract consist of two components with constant Rf values, the components marked as A1 and A2 . A1 shows higher activity against bacterial strains while T.harzianum extract consist of one component.The chemical structures of the isolated compound were

Abstract: During this study 23 species belong to 10 genera of imperfect fungi were isolated from different natural sources ( plants, soil , and ari) from Basrah govermanete using different isolation methods.Among the isolated fungi the genus Alternaria was selected to identify its species by using the morphological characteristis by light microscopy and Scaning Electron in Microscope (SEM) and verified by molecular and chemical methods. Eight species of Alternaria were identified namely; A.alternata (isolate1 and 2) A.chlamydospora A.citri, A.raphani , A.longipes , A.infectoria A.tenuissima and A.chrysanthemi based on light microscope examination.Taxonomic relegation of these species were confirmed by SEM image. SEM revealed that there was differences in the conidial wall ornamentation .The molecular analysis using PCR depending on the loci ITS1, and ITS4 700bp which confirmed the morphological identification of most of species namely A.alternata (isolate 1 and 2) , A.chlamydospora , A.longipes , A.infectroia and A.tenuissima. However , A.citri was related to A.alternata, A.raphani was belonged to A.infectoria and A.chrysanthemi is belonging to A.lolii. Nevertheless ,by using the loci OPA1 - 3 there was no variation among the species of Alternaria ,this is may be due to the inadequate method applied.The genetic variation of 36 isolates of A.alternata was studied using 9 - primers by RAPD - PCR technique. All primes gave an amplification of DNA for all the fungal isolates. Among the primers OPC08 exhibited a highest efficacy reaching 235 total bands .In the present study the antibacterial activity of fungal crude extract was tested. It appeared that the extract exhibit an antibacterial bioactivity against E.coli , S.aureus , S.epidermidis and S.saprophyticus.However, the extract of A.alternata (isolate 1 and 2) showed an inhibition growth against all the tested bacterial strains. This study was also revealed that the fungal filtrates of Alternaria species possessed various chemical compounds. However, there were differences in the chemical composition among the fungal filtrates.The results showed that Alternaria species ( A.alternata isolate 1 and 2, A.chlamydospora A.citri, A.raphani , A.longipes) were capable to biosynthesize silver nanoparticles, when the fungal filtrate were treated with AgNO3 solution after72 hrs incubation .Silver nanoparticles synthesis was checked by the change of colour from yellow to brown and confirmed by Uv - vis spectrophotometry at wave length (420, 440 nm). SEM image showed that the silver nanoparticles with spherical shape and size ranged between (20 - 72nm). Aconclusion can be derived that application of SEM,chemical analysis of fungi extracts ,molecular analysis and the silver nanoparticles characteristics are useful in the taxonomy of fungi to solve the overlapping of the morphological identification .Taxonomic key were prposed for the species of the genes Alternaria based on the morphology , chemical compound with the fungal extracts and size of silver nanoparticles synthesized by fungi .Melanin pigment identify by TEM microscope and it appeare like dark drop inside the cell .

Abstract: The current study was designed to investigate active compounds from different Penicillium isolates ,that isolated from different sources , using different media . Eleven isolates related to five species : P. chrysogenum, P.paxilli , P. citrinum, P. cosmopolitanum, P. digitatum were isolated. After primary screening was performed , the best isolates that have high antibacterial activity against gram positive and gram negative bacterial was selected. The selected isolates were cultured on fermentation media according to the suitable media for each isolate, and the active compounds were extracted using ethyl acetate as a solvent. P. cosmopolitanum and P. chrysogenum were cultured on penicillin production medium (PPM) , P. paxilli was cultured on Aspergillus complete medium (ACM) and P. digitatum and P. citrinum were cultured on solid state fermentation media consist of wheat bran . The efficiency of fungal crude extracts from each isolate against the reference strains S. aureus NCTC 6571 and E. coli ATCC 25922 and against Candida albicans (pathogenic and reference strain)was examined, and the Minimum inhibitory concentration (MIC) was determinated for each extracts.The inhibition zone of fungal extracts against E. coli and S. aureus ranged between (20 - 50) mm , and they had high activity against C. albicans ( reference and pathogenic isolate) ranged between 25 - 45 mm.Induction of secondary metabolite production by the selected fungi was carried out using biological factor (Streptomyces sp.) , chemical agent (colchicine) and physical agent by UV radiation. Apparently that the biological induction by Streptomyces isolate was the best compared with the other treatments.The results revealed that the two fungal extracts ALO1 and Apax exhibit a high antioxidant activity at low concentrations and volumes of the extract compared to ascorbic acid as control. ALO1 had radical scavenging activity (RSA%) reach 99.9% at volume 3μl , and Apax had RSA 91.6% at concentration 500μg/ml. Also, the fungal extract ,ALO1, showed a significant activity as anticancer agent against RD - cell line. The IC50 of ALO1 was 8.5μl after 24h and 23.76μl after 72h. The hypercholesterolemia ability of ALO1 in vivo and in vitro was assayed . In vivo experiment designed using female albino mice and divided into three groups each one contain 8 mice : group 1 treated with 10μl , group 2 treated with 20μl of ALO1 , and group 3 treated with normal saline as control group. The results showed that total cholesterol , triglycerides, LDL and VLDL were significantly reduced when compared with control group while the HDL level was increased in comparing with control group. The chemical analysis of the crude extracts showed that Apen2 contained 259 μg/g of penicillin G when analyzed with HPLC apparatus . Also the GC mass analysis of ALO1 showed that Docasadionic acid initialize area76.18% and Palmitic acid initialize area 15.09% from the total identified compounds.Whereas the GC mass analysis of Apax showed that Hexandioic acid initialize area40% and Stearolic acid initialize area 35.57% from the total identified compounds.In addition , it was detected the presence of penicillin biosynthetic gene cluster : pcbAB, pcbC and penDE in P. cosmopolitanum and P. chrysogenum.The result showed that gene pcbC and penDE were found in the genomic DNA but the gene pcbAB was not amplified by PCR.

Abstract: A study was carried out during the period from November 2010 to October 2011 to detect the intestinal parasites which contaminate the common fresh vegetables. A total of 303 samples were taken from three wholesale markets and three retail markets, in Baghdad province. Ten kinds common vegetables were selected. These vegetables were Celery (Apium graveolens); Parsely (Patroselinum crispum); Garden cress (Lepidium sativum); Leek (Allium porrum); Radish (Raphanus sativus); Lettuce (Lactuca sativa); Spinach (Ipomoea aquatica); Beet (Beta vulgaris); Mint(Mentha spicata) and Cabbage (Brassica oleracea).Sedimentation and floatation techniques were used for samples examination. Three different solutions (ZnSO4, saturated NaCl , saturated sucrose ) were used in floatation technique. The present study has been shown that the collected samples of vegetables were contaminated with sixteen species of intestinal parasites. It was found that the percentages of contamination with these parasites were as following : (Giardia lamblia) (29.4%), Entamoeba histolytica(24.5%), Entamoeba coli(16.9%), Balantidium coli (8%), coccidia(9.9%) and Blastocystis hominis(0.7%). For intestinal helminthes Ascaris lumbricoides (15.6%), Toxocara spp.(10.3%), Fasciola spp. (5.3%), Schistosoma haematobium (1.7%), Schistosoma masnsoni (1.4%), Taenia spp. (4.7%), Diphyllidum caninum (3.9%), Trichuris trichiura (3.3%), Enterobius vermicularis (6.9%) and Nematoda larvae (6.3%).The present study revealed that the percentage of contaminated vegetables by using sedimentation technique (72.3%) was significantly higher than that of flotation techniques (53.1%). Additionally it was found that, the different kinds of vegetables showed a significant difference in the percentages of contamination with the parasites in both techniques. Thus, the percentage of contaminated Garden cress was (93.5%), (72.4%) in both sedimentation and flotation technique respectively, while Cabbage showed (50%), (36.7%) respectively.A significant high percentage of contamination was recorded in Al - Nahrin wholesale market (89.2%) in comparison with low percentage (59.4%) in Al - Rasheed wholesale market. Additionally, it was found that the percentages of contaminated vegetables in wholesale (76.26%) were significantly higher from that of retail market (64.76%).The present study, also, showed that the percentage of detection of parasites by using ZnSo4 solution (31.2%) was more efficient than that showed by saturated sucrose (8.9%). Additionally; the soaking with normal saline (47.83%) showed a higher percentage of contamination than that by using distilled water (17.39%).The percentages of seasonal contamination were varied significantly, therefore, it was found that spring showed the highest percentage (29.7%) while summer the lowest (20.9%). The washed samples of Garden cress which obtained from the three wholesale markets, reduced the percentages of contamination with parasites but did not remove the parasites completely. Therefore, a significant difference has been noticed between washed (56.76%) and unwashed samples (76.66%).Concerning, the percentages of infections with intestinal parasites, it was found that the medical center (14 July) showed (29.4%) while Al - Ameria center (19.2%). Furthermore, the percentage of parasites infections was significantly higher in the summer (46%) than in winter (12.67%).The present study indicated that there were a positive coordination between the high percentages of contaminated vegetables and the high percentages of infection in the medical centers as in the case of G.lamblia and E.histolytica.Finally, it could be conducted that the contaminated vegetables played an important role in transmission of intestinal parasites to human, particularly, when these vegetables were eaten fresh without sterilization or good washing.

Abstract: تم اختبار قابلية عشرة عزلات للعفن Aspergillus fumigatus على انتاج الغليوتوكسين بوساطة تخمرات الحالة الصلبة وباستخدام الرز كوسط زرعي (ركيزة). اشارت نتائج الغربلة ان العزلة AF - 5 كانت هي الافضل واعطت اعلى انتاجية.كانت الظروف المثلى لانتاج السم على وسط الر | The ability of Ten Aspergillus fumigatus isolates for gliotoxin production were screened by solid state fermentation (SSF) using rice medium as substrate. The results indicated that, the AF - 5 isolate was the highest gliotoxin producer.The optimum conditions for gliotoxin production by AF - 5 isolate on rice medium were : - inoculum size 6×106 spores, moisturizing ratio (5 : 1) (w : v) with distilled water and incubation at 37 ?C for 10 days. Gliotoxin was purified from crude extract of AF - 5 isolate after production under the optimum conditions using solid state fermentation SSF. Purification of gliotoxin was achieved by two steps including : filtration and solid phase extraction. These processes were accessed to remove debris from crude extract and gives pure gliotoxin. The gliotoxin concentration was (122.6 ppm), which was detected by Thin layer Chromatography and High Performance Liquid Chromatography.The result of cytotoxicity effect of both purified extract and standard gliotoxin on human lymphocytes with exposure time of 24 hours at four different concentrations 25, 50, 100 and 200 ppb showed growth inhibition percentage 21, 39.10, 61.99, 87.45% and 17.89, 34.92, 58.34, and 85.22% respectively. The cytotoxicity effects have been done using conversion of the MTT to MTT formazan. After DNA was extracted from lymphocyte treated with toxin and analyzed by electrophoresis on a 1% agarose gel, gliotoxin appeared to have ability to damage the DNA. Results showed that both growth inhibition and DNA damage were increased gradually with the increasing of gliotoxin concentration.

Abstract: استهدفت الدراسة الحالية عزل وتشخيص الفطريات المستنبتة في اوراق نبات الاس Myrtus communis واختبار فعاليتها المضادة للاحياء المجهرية وفعاليتها الانزيمية. - اظهرت نتائج عزل الفطريات المستنبتة في 500 قطعة اوراق للحصول على عدد كلي للعزلات مساويا الى 99 عزلة ف | The present study was aimed to isolate and identify endophytic fungi from leaves of myrtle Myrtus communisand study their antimicrobial and enzymatic activities. - Results of fungal isolation from 500 leaves fragments revealed isolation of 99 endophytic fungi represented a total colonization frequency (CF) of 20.4%. These fungi were related to 23 species or isolates, where Aspergillus spp. prevailed over all others (11 species) with CF of 14% for all Aspergilli, Aspergillusniger and Aspergillusflavus showed the highest CF 7.2% and 3% respectively, other Aspergilli represented Aspergillusparvulus (CF 1.6%), Aspergilluscandidus (0.4%), Aspergillusraperi, Aspergillusclavatus, Aspergillusglaucus, Aspergillusornatus, Aspergillussclerotioniger, Aspergillusterreus and Aspergilluswentii were all showed CF of 0.2%.Other isolates fungi from leaves fragments were four morphologically different isolates of Penicillium with 0.4% CF for each. Additionaly, isolates of Cladosporium sp. (2%) and Cladosporiumcladosporoides (0.4%), as well as Cunninghamella sp., Drechsleraaustraliensis, Alternariaraphani, which showed 0.2% CF for each, Paecilomyces variotii (0.6|%), and different isolates of sterile fungi (White and Hyaline colonies) were also obtained. - Study the antagonistic activity of isolated endophytes using dual culture method against five plant pathogenic fungi(Fusarium oxysporum, Fusarium graminearum, Fusarium sp., Macrophomina phaseolinaandRhizoctonia solani)taking into account the percentage of inhibition of pathogenic fungi, results revealed variation of antagonistic activities between endophytes and pathogens. Different cases of antagonism were also appeared ranged from mycoparasitism of the endophytes on pathogens or vice versa, to competition between the two fungi and to the appearance of inhibition zone between them, this result may indicates the affinity of using some isolated endophytes in biological control applications against or controling fungal plant diseases. - Effect of ethylacetate extracts of culture broth of active endophytes shown in the last experiment against two bactria E.coli, S.aureus and the yeast Candida albicans using disc diffusion method, where filter paper discs were imprignated with different concentrations of fungal broth extracts. Results showed variation of inhibitory activity against bacteria with different endophytes, bacteria and conc. of the extract. Regarding the effect onC.albicans and filamentous fungi, most fungal broth extracts showed no inhibitory activity against yeast and no extract as well showed inhibitory activity on filamentous fungi. These results give indication thatbroth extracts contain antibacterial compounds. - Addition of 20% crude fungal broth of some endophytes to the culture medium showed significant inhibitory activity against filamentous fungi which did not respond to broth extracts, percentage of inhibition ranged between 0 - 77.08% and maximum inhibitory activity was shown by Penicillium sp. Isolate. These results give indication that some of crude filtrates contain antifungal compounds. - Analysis of broth extracts of some endophytes using TLC technique showed the content of extract of number of UV illuminated spots isolated on TLC pates having different Rf values, Bioautography showed inhibitory activity of some of these isolated spots against E.coli, S.aureus and the Filamentous fungus F.oxysporum. - Testing the extracellular enzymes activities of isolated endophyles on solid media, enzymes included amylase, lipase, pectinase, laccase, cellulase and protease showed variation in secretion of these enzymes, as well as, no endophytes showed the affinity of secreting all tested enzymes. Results also showed the high affinity of some endpohytes to secrete enzymes that could be use in multiple important applications after separation andcharacterizationof these enzymes.
