Biofilm formation and sensitivity to antibiotics of nasal S. aureus.

Abstract

The significant spread of antimicrobial-resistant strains among opportunistic bacteria is an important challenge for modern medicine and clinical microbiology in particular. The ability of bacteria to form biofilms is one of the adaptations for survival in unfavorable conditions, including the presence of antibiotics. According to modern theories and views on biofilm formation, it is believed that in nature, most bacteria are in the biofilm form, and their properties are significantly different from planktonic forms. The existence of biofilms of opportunistic bacteria in hospitals - on plastic, glass or metal surfaces, and instruments increases the threat of nosocomial infections. Staphylococcus aureus is a widespread organism that can colonize the skin and mucous membranes of healthy people and also remains one of the leading causative agents of inflammatory processes of various localizations. Healthy carriage of S. aureus among medical workers and also among medical students has an important epidemiological significance. The aim of the study. To investigate the biofilm-forming ability of S. aureus strains isolated from nasal carriers, and their sensitivity to antibiotics.
