Abstract: In the present study, attempt was made to isolate bacterial pathogens in blood and determination of their antibiogram. A total of 448 blood samples were analyzed. Out of which 405 (92%) samples of aerobic blood culture and 43 (8%) samples of anaerobic blood culture. From aerobic culture 111 (27%) pathogens and from anaerobic culture 6 (13%) pathogens were identified. In aerobic culture Staphylococcus aureus 71 (64.54%) was the most common cause of bacteraemia followed by Listeria monocytogenes 17 (15.45%), Diplococcus sp. 7 (6.36%), Salmonella typhi 6 (5.45%), Streptococci sp. 4 (3.63%), Klebsiella pneumoniae 3 (2.72%) and Campylobacter sp., E. coli and Haemophilus influenzae (single isolates of each, respectively). From anaerobic culture Clostridium perfringens 6 (13%) were identified. The antibiotic sensitivity test was done by disc diffusion method. The antibiogram of these pathogens showed resistance to cefotaxime, cefadroxil, cefaclor, cefuroxime, ceftazidime, ceftriazone and sensitivity to meropenem, linezolid and amikacin. Thus study indicated that the bacterial blood pathogens are becoming resistant to commonly used antibiotics, which may be due to indiscriminate use of these antibiotics. So it is very much important to have culture and sensitivity test of concern pathogens.
