Abstract

The purpose of work was to reveal the most typical pathogens of low respiratory tract infections (LRTI) in the pulmonology dept. in Belgorod regional clinical hospital of St. Ioasaf.Material & methods.During 2012-2013 sputum from patients with LRTI such as pneumonia, bronchitis & COPD has been analyzed. 1079 samples of biomaterial have been taken & examined with a help of semi-automatic analyzer, growth mediums & tests in bacteriologic laboratory of our clinic.Results.In 212 (19.6%) cases the sputum was regarded as 'low-quality' (saliva & saprophytes in the samples). Among the rest of samples 704 were with positive microbial growth (81.2%) & 163 (18.8%) were without one. 773 strains of LRTI pathogens have been collected. 2 pathogens per sample of sputum were found in 69 cases (9.8%).The main pathogens included as follows: S. pneumoniae (125 cases, 16.2%) & other Streptococcus spp. (168, 21.7%), S. aureus (82, 10.6%) & Staphylococcus spp. (74, 9.6%), Enterobacteriaceae (70, 9.1%) & Kl.pneumoniae (23, 3.0%), P.aeruginosa (15, 1.9%), Acinetobacter (6, 0.8%), Candida alb. (156, 20.2%). The sensitivity of these microorganisms has been studied additionally.Conclusions.1. LRTI pathogens most frequently found in the sputum were the following: Streptococcus spp. & S. pneumoniae, Enterobacteriaceae spp., S. aureus and Candida alb.2. Samples without microbial growth collected in the research could be caused by the atypical microorganism or virus. Therefore the special methods of research should be applied and carried out.3. The great number of low-quality samples have been revealed. Thus there is a necessity to increase the efficiency of sputum sampling in hospitals.
