Aim: To determine the bacteriological profile of pneumonia patients in tertiary care hospital. Methods: This study was carried out in the Department of Microbiology. Clinically diagnosed cases of pneumonia (symptomatic), patients who developed symptoms of pneumonia after 48 hours of admission to the hospital and patients who developed symptoms 48 hours after being administered on the ventilator. 100 patients were included in this study. Results: Staphylococcus aureus (8%), Coagulase negative Staphylococcus(8%) and Pneumococci(2%) were the common Gram positive bacteria isolated. Among the Gram negative bacteria, the commonest organism isolated was Klebsiella species (35%) followed by Pseudomonas species (25%), Acinetobacter (10%), E.coli (10%) and Providencia spp (2%). Methicillin resistance was seen in all 8 cases of Saphylococcus aureus isolates (100%) and in 8 case of CONS (8%). (82%), Norfloxacin, Levofloxacin and Meropenam (72% each). E.coli was sensitive to Amikacin (88%), Aztreonam (77%), Nitrofurentoin, Netilmicin and Meropenam (66% each). Conclusion: According to this study, most of the organisms are resistant to 3rd generation Cephalosporins. Further studies should closely examine the administration of initial therapy in pneumonia patients.
