Community acquired pneumonia (CAP) is a common clinical problem. The present study was designed to evaluate the clinical and bacteriological profile of CAP in Shimla.


Seventy patients with community acquired pneumonia were enrolled in this study. In all the patients blood culture, sputum culture, pleural fluid culture (if available) and serological studies for the detection of Mycoplasma pneumoniae specific IgM antibodies by enzyme linked immunosorbent assay (ELISA) were done.


Of the 70 patients, 53 (75.6%) had an identifiable atiology with 12 patients having evidence of mixed infection. No organisms could be isolated in 17 patients inspite of using serological methods for Mycoplasma pneumoniae, invasive procedures like bronchoscopic aspirations in addition to the conventional methods like sputum culture, blood culture and pleural fluid culture. The most frequent pathogen was Streptococcus pneumoniae (n = 19; 35.8%) followed by Klebsiella pneumoniae (n = 12; 22%), Staphylococcus aureus in (n=9; 17%), Mycoplasma pneumoniae (n = 8; 15%), Escherichia Coli (n = 6; 11%), beta-haemolytic streptococci (n = 4; 7.5%) and other Gram-negative bacilli (n = 5, 9%).


Age smoking and under lying co-morbid conditions specially chronic obstructive pulmonary disease (COPD) were significantly associated with the development of CAP (p < 0.01).
