Major bacteria of community-acquired respiratory tract infections in Turkey

Abstract

To determine the bacterial etiology of lower respiratory tract infections (LRTIs) in Turkey, quantitative cultures of sputum were carried out. The major pathogens for LTRIs were found to be Haemophilus influenzae, followed by Streptococcus pneumoniae and Moraxella catarrhalis. Only 6.1% of the H. inlfuenzae and all strains of M. catarrhalis were β-lactamase producers. An E-test showed that 31.2% of the S. pneumoniae strains had an intermediate resistance to penicillin, and the remaining strains were susceptible; no fully resistant strains were detected.
