Abstract:

A lab experiment was carried out in 2012-13 and the main objective of the investigation was, to study in vitro inhibition of enteric pathogens by Lactobacillus casei strains. The experiment was laid outin completely randomized block design with six treatments of test organism such as E.coli, Salmonella typhimurium, Staphylococcus aureus, Pseudomonas aeroginosa, Streptococcus mutans and Control. Supernatant of Lactobacilli grown on Man, Rogosa, Sharpe (MRS) media adjusted pH-7 and unadjusted pH showed antagonistic response against these test organism. Salmonella typhimurium was significantly superior over rest of other treatments, indicating that supernatant of lactobacili grown on MRS media and adjusted pH-7 showed good antagonistic response against Salmonella typhimurium.  Pseudomonas aeroginosa unadjusted pHand Streptococcus mutans unadjusted pH showed equal antagonistic response. E. coli unadjusted pH and Staphylococcus aureus adjusted pH showed equal antagonistic response.
