EPIDEMIOLOGY-BIOLOGICAL FEATURES OF THE ACUTE INTESTINAL INFECTIONS CAUSED BY STAPHYLOCOCCUS AUREUS

Abstract


Nowadays the structure of acute intestinal infections pathogens changed substantially. It is caused by constant evolution of bacteria and involvement of the opportunistic pathogens in the pathological processes. The aim of the study was to investigate the prevalence of the acute intestinal infections caused by staphylococci in the North-Eastern region of Ukraine, to determine the pathogenic factors in isolated pathogens. The materials for the study were the data of statistical reporting of Sumy regional sanitary-epidemiological station. Biological properties of the 50 Staphylococcus aureus strains were investigated. In the work used The descriptive and analytical techniques of the epidemiological, bacteriological and statistical methods were used. In the 2007–2012 the incidence of acute intestinal infections caused by staphylococci was in the range 17,1–20,3 on the 100 thousand. 2 year-old children were prevailed in the age structure. The largest numbers of cases were recorded in January, February, April, June and August. Strains of Staphylococcus aureus, isolated from the patients were characterized by a wide spectrum of pathogenic and persistence factors. Anti-lisozym activity was in 100% of the investigated cultures, anti-interferon and anti-complement activity were detected in 96,0 and 64,0% stains, ability to adhesion was present in 36,0% stains. At the same time anti-lisozym, anti-interferon and anti-complement activity were showed in the 52,0% stains of the Staphylococcus aureus. These data characterize negatively predicted for the near future regional trends in morbidity.
