Abstract: The present study was conducted in order to evaluate the activity of green alga Enteromorpha intestinalis extracts (methanol and hexane extracts) on growth and development of hydatid cysts of Echinococcus granulosus in vitro and in vivo by using mice type Mus musculus Balb\c that in comparing with albendazole drug. Anti - cancer activity was also evaluated in vitro for both algal extracts by using HeLa cells. Chemical compositions of algal extracts were analyzed by using Gas chromatography - mass spectroscopy (Gc - mass)technique . The hydatid cysts were collected from livers and lungs of infected sheep which slaughtered in Basrah abattoir. While, The algae specimens were collected from Abu Sokhir marshland area /north of Basra. The results revealed that E.intestinalis chemical compounds are carbohydrate , alkaloids, phenols , saponins , triterpenes and sterols compounds. In vitro study showed that the 1 mg / mouse weight of albendazole drug was able to reduce the percentage of protoscolices activity to zero after the third day of treatment. While, the dose 6 98 mg / kg of methanol extract inhibited all protoscolices after five days of treatment, followed by the dose 804 mg / kg of hexan extract that inhibited all protoscolices after six days of treatment.In vivo study revealed that the methanol extract (698 mg / kg) treatment was the best in reducing the weights of organs significantly in comparison with the positive control group it was 2.192 , 0.192 , 0.434 and 0.282 g of liver, spleen, lung and kidney respectively. The methanol extract (698 mg / kg) treatment lowered the average number of hydatid cysts (2.6) more than other extracts treatments , then followed by hexane extract (804 mg / kg) treatment it was 2.8 cyst .This study has identified that the liver enzymes Aspartate transaminase (ALT) and Alanine transaminase (AST) values in the serum of positive control group were higher significantly than negative control group the value of the enzyme ALT was 79 IU / l and the value of the enzyme AST was 118.4 IU / l.All methanolic extracts groups showed a preference in enzyme's values compared with other treatments groups , the value of ALT enzyme of 698 , 688 and 678 mg / kg of methanol extract groups were 46.8 , 45.8 and 44.6 IU / l respectively, while all hexane extracts groups showed a preference in AST enzyme values compared to the other treatments groups, the value of AST enzyme of 804 , 794 and 784 mg / kg of hexane extract groups were 73.6 , 70.2 and 70.4 IU / l respectively. Found a significant increase in the number of white blood cells WBCs in a positive control group ( 4.6 × 013μ), compared with a negative control group and the other groups, While it has been found significant decrease in the Hb (5..8deciliter) and Packed cell volume (PCV) (31..%) values in positive control group as compared with control negative group. The study found that the number of white blood cells WBCs n the methanolic extract group (678 mg / kg) was 4.06 × 103 microliter was as same as in the negative control group, In contrast, hexane extract group (804 mg/ kg) has did not significant difference with negative control group in the Hb and PCV were 11.5 g / dl and 36.8% respectively .Histological study confirmed that there are the histological changes in positive control group included congestion , bleeding , degeneration , infiltration of inflammatory cells and hyperplasia. Whereas the histological changes in group treated with albendazole were bleeding, infiltration of inflammatory cells , atrophy of the glomerulus and fibrosis in some areas . In algal extracts groups the histological changes were infiltration of inflammatory cells, bleeding and congestion.The Gc mass results revealed that the ethanol extract contains loliolide , ethyl stearate , palmitic Acid , ethyl palmitate , phytol , ethyl oleate , ethylhexyladipate and squalene compounds. While, hexane extract has N, Ndimethyltetradecylamine , diisobutyl phthalate , palmitic Acid , ethyl palmitate and ethylhexyladipate compounds.Anti - cancer study showed the algal extracts have an inhibition activity against cancer cells, The half maximal inhibitory concentration (IC50) value of the methanol extract was 79.08 μ/ ml, While, the IC50 for hexane extract was 156.3 μ/ ml.

Abstract: Fifteen isolates of Aspergillus flavus (AFL1 - AFL15) were isolated from multiple sources included soil, compost, seeds, fruits, feed and air. The isolates were identified morphologically then confirmed by molecular techniques. Only thirteen isolates were confirmed positively (AFL1 - AFL5 and AFL8 - AFL15) while two of them were not. A phylogenetic analysis was made which revealed that the isolates grouped according to their source of isolation. The aflR profile and phenotypic AFB1 production confirmed that all thirteen isolates posses the ability to produce AFB1 with significant differences (P ≤ 0.05) among them. Growth rate profile was performed under 30ºC which showed significant differences (P ≤ 0.05) among isolates. According to the above tests, A.flavus AFL14 was selected to be the experimental isolate for the rest of experiments in this study. Comparing to A.flavus NRRL3357 type strain, the impact of temperature, water activity aw and isolate factors was examined to determine the limits and optimum ecological conditions of growth of A.flavus AFL14. The results displayed that the best growth rate was (7.217 mm/day) at 0.98 aw where the lowest was (4.069 mm/day) at 0.9 aw with no growth at 0.85 aw while the impact of temperature demonstrated by outweigh of growth rate at 35ºC (6.201 mm/day) followed by 30ºC (5.272 mm/day) which exceeded 25ºC and 40ºC (4.604 and 4.051 mm/day), respectively.Bacillus subtilis (isolates : BSS1, BSS2, BSS3, BSS4 and BSW) and Pseudomonas fluorescens (isolates : PFMst and PFDL) were elected to be used as biocontrol agents. All the isolates were passed the biochemical identification tests moreover, BSS4 and BSW isolates of B.subtilis and PFMst and PFDL isolates of P.fluorescens were confirmed molecularly which used later in all biocontrol experiments in this study. The ability ofbiocontrol agents to inhibit fungal growth was investigated and the resultsshowed significant inhibition impact represented by significant outweighof B. subtilis BSS4 (99%) on the rest of B. subtilis isolates followed by P.fluorescense PFDL and PFMst (92.29 and 86.19) %, respectively, with nosignificant differences (P ≤ 0.05) among them. The extra - cellular abilityof biocontrol agents to degrade AFB1 showed a high degradation abilityIpreformed by B. subtilis BSS4, BSW isolates and P. fluorescence PFMst,PFDL isolates (100, 100, 97.805 and 97.396%), respectively. Thedegradation residues administrated to rats to determine their effect onbiosystems, the blood parameters showed a significant reduction ofWBC, HB, RBC, and P.C.V while there was a significant increase inUrea, Glutamic pyruvate transaminase (GPT) Glutamic oxaloacetictransaminase (GOT) and MCV in AF+DMSO treatment comparing tothe negative and positive control. Water activity and biocontrol factorswere examined to control aflD and aflR expression and phenotypic AFB1production. When the experiment held using Nutrient Agar medium, asignificant inhibition of aflD and aflR expression (P=0.000 and 0.003),respectively performed by BSW at 0.94 aw comparing to 0.98 aw whileno significant inhibition was observed in the rest of the treatments. Allbiocontrol agents revealed high significant reduction of aflD and aflRexpression (P≤0.001) in each water activity level separately whichconfirmed by HPLC results. The phenotypic results showed that 0.94 awexceeded 0.98 aw in AFB1 reduction (2011 and 4280 ng/gm),respectively which agreed with gene expression results. When MaizeMeal Agar used as a medium, aflD expression presented a highsignificant increase at 0.98 aw relating to the NM level of each individualtreatment (P= 0.000 - 0.03) except PFDL+AFL14 which showed nosignificant aflD expression between both levels. aflR expression revealeda high significant reduction (P= 0. 000) caused by 0.98 PFDL+AFL14and 0.98 BSW+AFL14, respectively, while no significant differenceswere observed in the rest of the treatments or control. The HPLC resultsdisplayed a high significant reduction of AFB1 at 0.98 aw (8447 ng/gm)compared to (219000 ng/gm) at NM aw. The biocontrol agents caused ahigh significant reduction for both aflD and aflR expression (P=0. 000 - 0.043) under each individual water activity level while, HPLC resultsshowed non significant low reduction to the AFB1 performed by BSS4and BSW (25160 and 44790 ng/gm), respectively, followed by asignificant increase in AFB1 amount caused by PFMst and PFDL(267600 and 184100 ng/gm), respectively
