The influence of Lactobacillus strains (L.fermentum, L.brevis, L.plantarum, L.curvatus, L.vulgaricus, L.casei, L.acidophilus and L.lactis) on the inactivation of human pathogens (Staphylococcus aerians, Salmonella typhi, S.paratyphi, Klebsiella oxytoca, Pseudomonas aeruginosa, Vibrio parahaemolyticus, Proteus mirabilis, Lactobacillus vulgaris, Vibrio cholerae and Shigella flexneri) were investigated. Strong antibacterial activities were exhibted on the plates inoculated in the Shigella flexneri by L.curvatus, L.plantarum and Proteus mirabilis and Pseudomonas aeruginosa by L.vulgaricus. L.plantarum showed broad spectrum of antibacterial activity against all tested pathogens. A weak inhibitory effect was detected in L.brevis on Vibrio parahaemolyticus and L.fermantum on L.vulgaris and S.typhi.
