Abstract

The composition of vaginal bifidoflora in 56 clinically healthy women of reproductive age was studied. The study revealed that four species of bifidobacteria, viz. Bifidobacterium bifidum, B. breve, B. adolescentis 2 and B. longum, dominated in the composition of this bifidobacterial population. Nine out of 11 isolated strains were found to be capable of inhibiting indicator microorganisms Staphylococcus aureus and Enterococcus faecalis when tested in vitro; in addition, strains B. adolescentis 2 F1, B. bifidum G1, B. breve P2 and B. longum Z4 inhibited Klebsiella ozaenae, Pseudomonas aeruginosa, Escherichia coli and were also active acid producers. Three of these 4 bifidobacterial strains were capable of adhesion to vaginal epitheliocytes, while B. bifidum G1 was practically incapable of adherence to these cells, similarly to B. bifidum strain 791 of intestinal origin. In addition, the spectra of antibiotic susceptibility varied from strain to strain, but all bifidobacterial strains were susceptible to benzylpenicillin and resistant to lomefloxacin, most of them being also resistant to cyprofloxacin and gentamicin. Thus the data presented in this work are indicative of the possibility and advantages of using bifidobacterial strains belonging to this ecological niche as probiotics for the correction of the microflora of the urogenital tract in females.
