Abstract

Community Acquired Pneumonia (CAP) is defined as an acute infection of the pulmonary parenchyma in a patient who has acquired the infection in the community, as distinguished from hospital acquired (nosocomial) pneumonia (HAP).[6,7] The study is conducted to analyse the sputum bacteriology and antibiotic sensitivity pattern in patients having community acquired pneumonia. When the culture report is obtained, the treatment has to be changed according to the isolated organism. Methods: A Prospective observational study was conducted among patients admitted to the pulmonology, paediatrics and general medicine department of a teritiary care hospital. Patients who met the inclusion criteria were enrolled. Informed consent forms were taken from every patient after the procedure is being explained. The individual bacterial isolates and their sensitivity pattern to various antibiotics were also recorded. The result was later analysed, documented and then presented. Result: About 54.08% of cultures were positive for pathogenic bacteria. Among the pathogenic bacterial growth there are, 5 types of bacterial strain, out of which 3 were Gram negative bacteria 60% and 2 were gram positive bacteria 40%. The most common pathogenic bacteria isolated in sputum culture was Klebsiella pneumoniae followed by Staphylococcus aureus, Streptococcus pneumonia, Pseudomonas aeruginosa, Haemophilus influenza.

Keywords: CAP, pneumonia, sputum culture, Gram positive, gram negative.
