Lower respiratory tract infections (LRTI’s) are the most frequent infections among patients in intensive care units. The consequences of increased drug resistance are far reaching since bacterial infection of the lower respiratory tract is a major cause of death from infectious disease. This was a prospective study of clinically suspected cases of LRTI’s over a period of 6 months from Jan 2019 to June 2019. Lower respiratory tract samples were inoculated on BA, CA, MAC agar and incubated overnight & AST was performed after identification. 124 (88.5%) of total 140 samples were positive for bacterial culture. 118 (84.28%) were gram negative bacilli (GNB) and 6 (4.2%) were gram positive cocci (GPC). Occurrence of LRTI was 71.4% with dominance of males and age group of 20-65 years. Klebsiella spp. (59.28%) was the most common isolate followed by Pseudomonas aeruginosa (11.4%), E. coli (7.1%), Acinetobacter baumannii (6.4%), Staphylococcus aureus(4%). Susceptibility of GNB was highest towards Imipenem followed by Piperacillin-tazobactam. Gram positive organisms exhibited highest susceptibility towards Vancomycin and Linezolid. The resistance pattern of these pathogens can help to formulate effective antimicrobial policy. Therefore, an ultimate and detailed bacteriological diagnosis and susceptible testing is required to overcome global problem of antibiotic resistance.
