A nosocomial infection or healthcare-associated illness that develops in patients after they are admitted to the hospital but was not present or incubating at the time of admission is referred to as a hospital acquired infection. In patients with severe viral and fungal infections today, it is one of the most prevalent and life-threatening consequences. Blood culture is one of the most important diagnostic tools for the diagnosis of hospital acquired infections. It can also help in providing a

Materials and Methods: All samples were obtained and processed using conventional microbiological techniques, and an antibiotic sensitivity test was carried out in accordance with CLSI recommendations. Results: Total 160 samples were processed, out of which 54 (34%) samples were positive. Out of 54 positive blood sample, maximum samples were from NICU (28) 52%, followed by causality (10) 18%, PICU (4) 7%, HDU (2) 3%, intensive careunit (4) 7%, surgery (6) 11%, and overall males contributed to higher positivity rate. Total nine different organisms were isolated, out of which Gram negative bacilli were comprised 40 (74%), Gram positive cocci 8 (14%) and Candida were 6 (11%). Among Gram-negative bacilli of most common species were Klebsiella pneumonia (30%), Acinetobacter baumanii (18%), Pseudomonas aeruginosa (11%), Burkhoderia cepacia (11%), and Serratia fonticola (3%). The most prevalent isolated species of gram-positive cocci were Staphylococcus aureus (11%), Coagulase negative S. aureus (3%), and Enterococcus faecalis (3%). Conclusion: This study on blood culture gives insight to magnitude of hospital acquired infections in our set up. Again result of antibiotic susceptibility tests gives overview of drug resistance problem at our set up. This may help in antibiotic stewardship program.
