Coagulase-negative staphylococci as a significant fact of generalization of infection in persons with a burdened comorbid background

Abstract

Since the era of the widespread introduction of antibiotics into the human sphere of activity, the problem of antimicrobial resistance has become an urgent and very important topic around the world. Recently, coagulasonegative staphylococci (CoNS), which are representatives of opportunistic microorganisms of the microbiome of the skin and mucous membranes of healthy people, have made a certain contribution to its progression. For a long time, they did not pose a threat to patients, but in recent decades among microorganisms they have been seeded in more than two-thirds of patients with postoperative mediastinitis, catheter-associated infections, as well as from wounds of the neck vessels and the inguinal region separated by pacemaker beds. This paper discloses, using clinical examples, the significance of CoNS in the formation of systemic inflammatory response syndrome in patients with a burdened comorbid background (type II diabetes mellitus, grade 3 arterial hypertension). During the examination of patients, it was shown that skin defects are foci of persistent bacteremia of representatives of the CoNS group, which can cause the development of a systemic inflammatory infectious response with the formation of resistant strains of the opportunistic flora of the microbiome of the skin and mucous membranes. It has been shown that to determine the tactics of antibacterial therapy, a bacteriological study of all detected foci of infection in patients, screening of pathogens and their sensitivity to antibiotics, and especially in persons at risk, is necessary. This will increase the effectiveness of antibacterial therapy and reduce the possibility of forming resistant strains of pathogens.
