Dynamics of the etiological structure from sputum of patients with pneumonia
Microbiological characteristics of respiratory infections change specific structure. Therefore, constant microbiological monitoring of specific structure, specific properties, and antibiotic resistance is required.
The purpose of this research is to produce a dynamic analysis of microbial spectrum from sputum of patients with pneumonia at the National Medical Research Centre.
From 2007 to 2012, 400 strains of microbes were isolated from sputum of patients with pneumonia. Identification was determined by the microbiological computer analyzer ?Vitek 2-Compact?.
Comparative analysis of the microbial landscape showed that S.pneumoniae had a high level of detection. It increased from 37.5% in 2007 to 45% in 2012. In the same period, sputum detection of Enterococcus faecalis increased from 1.7% to 10%, and of Candida albicans from 1.7% to 4.2%. At the same time, there was a decrease in detection of Streptococcus pyogenes by 3 times and Moraxella catarrhalis by 2.5 times.
Thus, our results showed that the basic pathogen of pneumonia was Streptococcus pneumoniae.
