A total of 25 samples of raw cow milk, were collected randomly from street vendors and supermarkets in Zagazig city, Egypt for detection of the probiotic potential of some isolated Lactobacillus strains from raw milk. The obtained results revealed that the Lactobacillus Strains were detected in all the examined samples. The isolated strains were slightly affected by pH 3 and bile condition (0.5%). The obtained results displayed resistance against Erythromycin, Gentamycin and Tetracycline. Meanwhile, Ampicillin, Chloromphnicol, Steptomycin and Vancomycin exhibited an effect against some strains. The isolated strains produced ?-hemolysis, NaCl tolerance was positive for these strains. Also, ? galactosidase was produced.
