GENETIC PROFILE STAPHYLOCOCCUS AUREUS, ISOLATED FROM BACTERIAL CARRIERS AND PATIENTS WITH INFECTIOUS INFLAMMATORY PATHOLOGY

Abstract

Aim. A comparative genetic evaluation of the pathogenic potential of Staphylococcus aureus strains isolated from bacterial carriers and patients with infectious inflammatory pathology. Materials and methods. The presence of pathogenicity genes (ssp, spa, clfA and clfB) in 163 strains of S. aureus isolated from the mucous membrane of the nasal cavity of bacterial carriers, from the vaginal discharge of women with uterine myoma, the contents of the pustules of newborns with perinatal pyoderma, and the transudate of venous-trophic ulcers lower limbs and purulent wounds in patients with diabetic foot syndrome. Results. It was shown that the frequency of occurrence of ssp, spa, clfA and clfB genes in clinical strains of S. aureus depended on the source of their isolation. In all cultures of S. aureus (except vaginal isolates), the most common gene was ssp (in 66.7 - 94.6% of cases), which was found isolated or in different combinations with other genes (spa, clfA, clfB). It has been established that the genetic profiles of strains of S. aureus isolated from bacterial carriers and patients with infectious inflammatory pathology (perinatal pyoderma, purulent wounds in diabetic foot syndrome) show a pronounced similarity in the presence of ssp, spa, clfA and clfB genes. Conclusion. The possible role of asymptomatic carriage of strains of S. aureus with a pathogenic potential in the development of endogenous infections of different localization is discussed.
