In vitro inhibition of enteric pathogens by Lactobacillus casei

A laboratory experiment was undertaken to check the inhibition of enteric pathogens by lactobacillus casei strains. The test organism such as Escherichiac oli, Salmonella typhimurian, Staphylococcus aureous, Pseudomonas aeroginosa, Streptococcus mutants were grown on neutral pH media. Supernatant of Lactobacilli grown on neutral pH showed antagonistic response against Salmonella typhimurium and Pseudomonas aeruginosa. Antagonistic effect on Salmonella typhimurium was significantly superior over other microbes followed by Pseudomonas aeruginosa and Staphylococcus aureous.
