Abstract:

Urogenital tract infections are increased currently. Microbial pathogens include both bacteria and fungi. Due to appearance of multi drug resistant bacteria from urogenital system, search for new ways to control such pathogens is necessary. Probiotics are used herein to control urogenital pathogens. The probiotic bacterium Enterococcus faecium NM₂ isolated from urine of healthy people was used for production of cell free supernatant (CFS) containing both acids and antimicrobial proteins (bacteriocins). Urogenital bacterial and Candida albicans TW₂ strains were used as the indicator organisms. Common methods of antibiotic sensitivity and bacterial or candidal inhibition were followed in this study. The probiotic bacterium E. faecium NM₂ survived in presence of antimycotic agents. It was resistant to 70% of the antibiotics used. Its cells and either CFS or Neutralized CFS (NCFS) inhibited the urogenital bacteria and C. albicans TW₂ fungus used. E. faecium NM₂ cells inhibited all the urogenital microorganisms used. CFS obtained from this probiotic bacterium showed higher antibacterial and anticandidal activities than that obtained by NCFS. E. faecium NM₂ possessed the capability to be used as probiotic for protection against urogenital pathogens.
