Community Acquired Pneumonia (CAP) is an infection of pulmonary parenchyma. Despite availability of potent antibiotics, CAP remains a common and serious illness with significant morbidity and mortality. Objective of the study is to identify the bacteria causing community acquired pneumonia and risk factors associated with it. 100 clinically diagnosed CAP patients attending medical out-patient and admitted in Upgraded Osmania General Hospital selected. Study was conducted during Sept 2016 to Oct 2017. Sputum samples were cultured and organism identified by standard biochemical tests. Out of 100 included, 52 had identifiable etiology. Most frequent organism was Klebsiella pneumoniae (n=27) followed by Staphylococcus aureus (n=14). People in the age group of 45-65 years were more susceptible. Major risk factor was smoking.
