Bacteraemia is one of the important causes of mortality and morbidity worldwide. The emergence of multidrug-resistant bacterial strains is a major problem in its management. To encourage the prudent use of appropriate antibiotics in a tertiary care study was undertaken. A total of 282 patients with suspected bacteraemia from indoor and outdoor patients were included in this study. Blood samples were processed in the microbiology laboratory and bacteria were recognized by standard laboratory methods and then antibiotic susceptibility test was performed following CLSI guidelines. Out of a total of 282 blood samples, 55(19.50%) were culture positive. Among 55 positive cultures, Gram-positive Cocci and Gram-negative Bacilli were 48(87.3%) and 7(12.7%) respectively. The most predominant organisms were Staphylococcus aureus comprising 42(76.36%), followed by Salmonella typhi 4(7.30%), E. coli 2(3.63%) and Acinetobacter spp 1(1.81%). Among the isolated Staphylococcus spp, only 6(10.9%) isolates were Coagulase-Negative (CoNS). In antibiotic susceptibility test, all of the isolated bacterial pathogens were found susceptible to imipenem and meropenem (100%). For Salmonella typhi, all 4 isolated strains were found resistant to amoxicillin, amoxicillin+clavulanic acid (amoxyclave) and cephradine and 3 out of 4(75%) were susceptible to ciprofloxacin and levofloxacin. Most of the Gram-positive Cocci (GPC) were susceptible to levofloxacin (90%), ciprofloxacin (85%), and amikacin (83%). Both of E. coli and Acinetobacter spp were sensitive to amikacin (100%). This study stresses the need for continuous screening and surveillance for antibiotic resistance that would influence appropriate empiric treatment and infection control strategies for bacteremic cases.
