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.

المستخلص: 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.

المستخلص: 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.

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.
