Abstract

Infectious diseases are the leading cause of death across the world. Evolution of antimicrobial drug resistant bacteria is a major health concern and extremely difficult to overcome. Nosocomial infections encompass all the clinical infections that do not originate from patients, originally admitting diagnosis. Critically ill patients have greater risk of developing nosocomial infections with resistant strains. Its incidence in developing nations is 5-10%. However, in India one in four patients admitted in hospital acquire nosocomial infections. These incidences are 4-5 times greater in general ward. In the present investigation strains of E. coli, Staphylococcus, Klebsiella, Enterobacter were isolated and identified based on morphological and biochemical tests, and were tested for their antibiotic susceptibilities. All the isolates were resistant to ampicillin and penicillin; however, they were sensitive to streptomycin, chloramphenicol and tetracycline. This study is an attempt to detect the presence of antibiotic sensitive / resistant pathogens in government hospital.
