Bacteriological Profile and Antibiotic Sensitivity Pattern of Micro Organisms from Community Acquired Pneumonia.

Community acquired pneumonia (CAP) is a public health problem. The aim of the study was to determine the etiological agents of the CAP and the antibiotic sensitivity pattern of the isolates in Bangalore. Hundred prospective patients with CAP were included in the study. Blood culture was done in all the cases and sputum culture was done in 66% of cases. Out of 100 patients, the etiology was established in 39% of cases from sputum and blood culture. Rate of isolation of organisms from sputum and blood culture was 54.5% (of 66 samples) and 4% (of 100 samples) respectively. The predominant organism from sputum culture was Klebsiella spp followed by Streptococcus pneumoniae, Pseudomonas spp and others. The predominant organism from blood culture was Staphylococcus aureus followed by Klebsiella spp. The isolates showed best sensitivity for third generation cephalosporins, fluoroquinolones and aminoglycosides. CAP incidence increases with increasing age and with risk factors like smoking, COPD and diabetes mellitus. Most common organism isolated were Klebsiella spp followed by Streptococcus pneumoniae, Pseudomonas spp and others, with best
