title: Changing bacteriological profile and mortality trends in community acquired pneumonia.
abstract: There are very few and conflicting Indian data regarding the bacteriological etiology of community acquired pneumonia (CAP). Adding to this agony, there is no credible data from the eastern part of India. This is a cross-sectional study and descriptive in nature over a period of 1-year. Of the 464 cases of the study population, we could isolate aerobic bacteria in 149 patients (32.1%). Streptococcus pneumoniae has been identified as the most common organism causing CAP (68/149). Gram-negative bacilli (GNB) as a group exceeded marginally over S. pneumoniae (69/149). Among GNB, Pseudomonas aeruginosa was the most common organism (31/69), followed by Klebsiella pneumoniae (29/69). Staphylococcus aureus was identified in (12/149) cases. Co-amoxyclav is still the most sensitive drug for S. pneumoniae. P. aeruginosa was most sensitive to imipenam followed by piperacillin-tazobactam.
