Functional activity of Lactobacillus spp. isolated from the genital tract under the unfluence of putrescine and cadaverine

Functional activity of Lactobacillus spp. was evatuated under the influence of bacterial diamines. The dose-dependent effect of putrescine on growth characteristics of clinical strains has been established. Cadaverine at a concentration of 1 mmol/l in the culture medium significantly stimulated the accumulation of biomass of the tested strains. The results obtained confirm the destabilizing effect of bacterial amines agents on vaginal Lactobacillus spp. and thus their important direct role in weakening the biological protection of the vaginal microenvironment.
