The Impact of Norepinephrine on Mono-Species and Dual-Species Staphylococcal Biofilms.

The effect of norepinephrine ("NE") on Gram-negative bacteria is well characterized; however, little is known about the impact of NE on cutaneous Gram-positive skin residents, especially staphylococci. In this study, the impact of NE on monospecies and dual-species biofilms of and model strains was investigated for the first time. Biofilms were grown in two different models (on polytetrafluoroethylene ("PTFE") cubes and glass microfiber filters ("GMFFs")) and additionally kinetic measurements of bacterial growth was performed.

Atrial Natriuretic Peptide Affects Skin Commensal and Dual-Species Biofilms.

The first evidence of the atrial natriuretic peptide (ANP) effect on mono-species and dual-species biofilms of skin commensals and was obtained in different model systems. Elucidation of the mechanism of action of hormones on the microbial communities of human skin is an important physiological and medical aspect. Under anaerobic conditions, ANP at a concentration of 6.
