Аннотация

Human natriuretic peptides (NUPs) types A and C were shown have different effects on the growth of monospecies and binary biofilms of human skin commensal microorganisms Staphylococcus epidermidis and Staphylococcus aureus. The effect of natriuretic peptides depended on cultivation conditions: at 37°С growth of monospecies biofilms formed by S. epidermidis and S. aureus was stimulated and inhibited, respectively, resulting in changed values of the biofilm average thickness and biomass in presence of NUPs. At 33°С effects of NUPs reversed: growth of S. epidermidis monospecies biofilms was inhibited. In binary biofilms at 37°С, NUPs were able to increase the competitiveness of S. epidermidis against S. aureus. NUPs affected predominantly biofilms and, to a lesser degree, planktonic cultures. This phenomenon makes it possible to consider NUPs as the molecules able to regulate the interactions between the human organism and skin microbiota.
