Bacteremia is considered one of the most important causes of mortality and morbidity worldwide, especially among sick people. This study aims to analyze bloodstream infection among indoor and outpatients with acute febrile illness at Khwaja Yunus Ali Medical College &Hospital (KYAMC&H), Enayetpur, Sirajganj. This study tracks and analyzes the culture results of 406 blood samples received in the department of microbiology at KYAMC&H throughout the past 4 months from suspected patients with bloodstream infection. The samples were prepared by exploiting the machine-controlled Automated Blood Culture System BACTECTM FX40 (USA). All the isolated pathogens were identified using the biochemical method, except for Burkholder cepacia complex (BCC), which was identified using BD Phoenix™ M50 (USA). A total of 105/406 (25.9%) BACTEC 9120® system-positive samples were subculture on 7% sheep blood agar, MacConkey agar, and chocolate agar plates. The majority, 63 (60%) of those, were Gram-negative microorganisms, and only 42 (40%) isolates were Gram-positive pathogens. The most predominant organisms were Staphylococcus aureus, comprising 40 (38.1%), followed by Salmonella typhi 18(17.1%), E. coli 28(26.7%), Klebsiella pneumoniae 4(3.8%), Burkholder cepacia complex 5(4.8%) and others 10(9.5%). In antibiotic susceptibility tests, most of the isolated bacterial pathogens were found susceptible to Imipenem and Meropenem.
