THE CHANGE OF ETIOLOGICAL STRUCTURE OF UPPER RESPIRATORY TRACT INFLAMMATORY DISEASES FOR FIVE YEARS

Abstract

Bacteriological research of various clinical materials from 236 patients with infectious diseases of the upper respiratory tract in 2010 and 347 patients in 2015 was conducted. Microbiological examination included an isolation of pathogens, identification by morphological, cultural and biochemical properties.

The study found that there was a clear trend of increasing the share of Candida spp. in the etiological structure of upper respiratory tract infectious diseases since 2010 to 2015. The significant role of S. aureus, S. epidermidis, and streptococcus of viridans group remained unchanged, and a decrease in their relative share was due to the spreading of pathogens by other opportunistic microorganisms (enterococci, enterobacteria, Proteus, Corynebacterium, Escherichia coli and Pseudomonas aeruginosa). S. aureus was presented to a large extent in all organs of upper respiratory tract, streptococcus of viridans group predominated in the nasopharynx significantly, and most of all S. epidermidis was isolated from a nose. Throat diseases were caused by fungal and bacterial associations in most cases. Proportion of Candida species was 22.9 % furthermore 85.8 % of the strains isolated from the nasopharynx, and 81.8% of the strains isolated from the external ear have been presented in association with the bacteria.

The obtained data confirmed the requirement to determine the most significant pathogenic flora, which causes diseases of the respiratory tract organs, monitoring it at the level of the individual patient, as well as at the regional and country level.
