| Abstract | ||
| Lactobacillus is one of Lactic Acid Bacteria group, they are known to exhibit antagonistic activity against pathogenic organisms. This study evaluates the protective effect of Lactobacillus acidophilus Crud Bacteriocin like substance against growth of some food borne pathogenic bacteria. Antimicrobial effect of crud bacteriocin like substance was tested against the growth of S. typhi and S. aureus that isolated from food samples by agar well diffusion assay. The results showed that the crud extract of bacteriocin like substance had antibacterial activity against the two tested bacteria, and the effect against S. typhi was greater than that of S. aureus , the zone of inhibition was (15)mm against S. typhi and (12)mm against S. aureus . The antibiotic susceptibility test was also studied against the two foodborne pathogenic bacteria.This study aims to screen the antibacterial activity of crud bacteriocin like substance from lactic acid bacteria against two food borne pathogens. | ||
