Abstract
Examination of the lower respiratory tract infection agents frequently seen in our region and determination of their antibiotic susceptibility rates were aimed in this study. For this purpose, during the first six months of 1999 at İzmir Göğüs Hastalıkları ve Göğüs Cerrahisi Hastanesi, 365 sputum and bronchial aspiration samples were collected from hospitalised and outpatient cases. Collected samples were studied by gram stain and bacteriological culture methods. Antibiograms were performed according to NCCLS standards by Kirby Bauer disc diffusion method. Fifty-seven H. influenzae (%16), 43 M. catarrhalis (%12), 25 S. pneumoniae (%7) strains were isolated. Nineteen out of 57 Haemophilus strains were serotype b. Resistance to ampicillin and erythromycin among the Haemophilus strains were %46 and %48, respectively. The lowest resistance rates were detected on ampicillin-sulbactam and ceftriaxon. Moraxella stains showed highest resistance rates to trimetoprim-sulfametoxazol as %87. Incidence .
