  • Purpose: The probiotic effects of lactic acid bacteria have widely been researched in diverse human pathogens, but only a few effects are reported against oral pathogens. The antimicrobial effects of the Enterococcus faecium 7413 isolated from Korean infants on the 9 pathogen including 6 oral streptococci were investigated the clinical use of the antimicrobial peptide for oral microflora control. Materials and Methods: E. faecium 7413 was identified by morphological, biochemical tests and 16S rDNA sequence analysis. Inhibitory effects of culture supernatants were determined for their ability to grow on agar plate containing pathogenic bacteria. Result: The culture supernatant of Enterococcus faecium 7413 showed inhibitory effects on oral pathogens, namely Streptococcus pyogenes KCTC 3556, S. pneumoniae KCTC 5080, S. mutans ATCC 25175, S. anginosus ATCC 33397, S. constellatus KCTC 3268, S. intermedius ATCC 27823 and Shigella flexneri KCTC 2008. Whereas it did not affect the multiplication of E. coli strains, KCTC 1041 and ATCC 43894. Conclusion: The data obtained in this study could be useful for future development of effective probiotics allowing prevention for oral pathogens.
