| Abstract | ||
| this study was aimed to know the effect of Bifidobacterium longum on some pathogenic bacteria such as Staphylococcus aureus . Salmoella typhi , Escherichia coli and Klebsiella pneumonia, These pathogenic bacteria were added to the milk as alone .the milk was inoculated by Bifidobacterium longum . then the flasks were incubated at 37 C for seven days . Bacteriological and chemical test were performed on all flask every day ( 24 hours ) . Total count for pathogenic bacteria . acidity and pH were measured and ratio of decreasing of pathogenic bacteria was calculated during incubation period until seventh day of incubation . Control samples for each one of pathogenic bacteria without B. longum . The results were shown that the higher ratio of decreasing was E. coli which reached 98.85 % compared with control sample which reached with 38.31% at the end of the incubation period. The higher acidity was reached 1.11% as lactic acid in the same incubation period. but the other pathogenic bacteria : Staph. aureus , Samonella typhi , and klebsiella pneumoniae. , were shown 93.83 % . 93.55% . 92.49 % respectively . | ||
