Comparative characteristic of the staphylococcus biological properties isolated from tear fluid, the cavity of the nose and the pharynx of patients with endogenous uveites

A comparative analysis of the biological properties of staphylococci isolated from tear fluid, nasal cavity and pharynx of patients with endogenous uveitis was carried out. Rather wide species diversity of microorganisms of the genus Staphylococcus was found in these locuses, with S. aureus isolated in 23.8, 33.3 and 26.2% of cases, respectively. It has been established that a certain spectrum of virulence and persistence factors, which is more characteristic of S. aureus, is inherent in staphylococcal strains. The vegetation site of Staphylococcus cultures did not affect their presence and spectrum. The isolates obtained from the tear fluid, in their biological characteristics did not differ from the inhabitants of the nasal cavity and pharynx. Based on the results of studying the pheno- and genotypic characteristics of S. aureus isolated from different biotopes of the same patients, it was shown that the tear fluid colonized S. aureus from the nasal cavity and pharynx. Resident carriage of S. aureus can be considered as a risk factor for various inflammatory diseases of the eye.
