Preparation of acidophilus soy milk and its therapeutic effect against gastrointestinal pathogens

This study evaluates the therapeutic effect of acidophilus soy milk against intestinal infection causing pathogens. Lactobacillus acidophilus strains were isolated from curd and identified based on the colony morphology and biochemical profile. Using Lactobacillus acidophilus fermented soy milk was prepared. Its antimicrobial efficiency was identified against five pathogens such as Escherichia coli, Salmonella typhi, Shigella dysentriae, Vibrio cholera and Staphylococcus aureus. Among these five pathogens Vibrio cholerae was effectively inhibited by acidophilus soy milk.
