Distribution of the causative agents of respiratory tract infections in children

Abstract

The study aimed to investigate the prevalence of microorganisms depending on the site of isolation and disease. The study involved 48 children aged 1 to 17 years. The patients were diagnosed with acute bronchitis (54.17%), community-acquired pneumonia (CAP) (33.33%), bronchial asthma (12.50%). 173 strains of microorganisms were isolated. 106 strains (61.3%) of Gram-positive icroorganisms, 49 strains (28.3%) of Gram-negative microorganisms, 18 strains (10.4%) of fungi were detected. The study implied assessment of 100 samples from the nose (nasal swabs), pharynx (throat swabs) and sputum. Gram-positive microorganisms were isolated in 83 cases, Gram-negative microorganisms in 36 cases, fungi in 18 cases. The assessment showed that Staphylococcus aureus was most often isolated from patients with acute bronchitis; Gram-negative microorganisms were most often detected from throat swabs, comparing with microorganisms detected from nose swabs and sputum.
