Background: Lower respiratory tract infections (LRTIs) are common among patients worldwide, and the most major cause of pneumonia and bronchiolitis in hospitalization.The present study was conducted to assess bacterial pathogens from lower respiratory tractinfections. Materials & Methods: 75 patients of both genders were enrolled. All patients were from out patient department (OPD), in patient department (IPD), and intensive care unit (ICU). The respiratory tract samples (sputum, bronchoalveolar lavage [BAL], endotracheal aspirate, gastric lavage, etc.) were obtained from the patients. Results: Out of 75 patients, males were 42 and females were 33. Common organisms isolated were psuedomonas species in 35%, pseudomonas aeruginosa in 24%, acinetobacter species in 16%, proteus species in 5%, klebsiella species in 4%, Escherichia coli in 3%, Enterobacter aerogenes in 6% and Streptococcus pneumonia in 7%. The difference was significant (P< 0.05). The location of patients was ICU in 28, IPD in 30 and OPD in 37. Samples were bronchoalveolar lavage in 16, sputum in 52, gastric aspirate 4, ET tube in 2 and Endotracheal aspiratein 1 case. The difference was significant (P< 0.05). Conclusion: Common organisms in LRTI patients isolated were psuedomonas species, pseudomonas aeruginosa, acinetobacter species, proteus species, klebsiella species, Escherichia coli, Enterobacter aerogenes and Streptococcus pneumonia.
