    Bacterial bloodstream infections (BSIs) are a significant cause of morbidity and mortality among hospitalized patients, and data in resource-limited countries are sparse.

    A hospital-wide retrospective analysis of microbiologically proven bacteremia was conducted. Sociodemographic data, comorbidities, bacterial isolates, and their antimicrobial susceptibility pattern were recorded.

    Of the 276 episodes of bacteremia studied, 130 (47.1%) occurred in females. The overall mean age was 15.29 ± 23.22 years. Community-acquired BSI was seen in 179 (65.0%) of the patients, whereas 97 (35%) was hospital-acquired BSI. Gram-negative bacteria 158 (57.2%) were the leading cause of BSI. More than 60% of the isolates were resistant to commonly prescribed antibiotics, especially trimethoprim-sulfamethoxazole, ampicillin, and amoxicillin–clavulanic acid.

    Gram-negative bacteria are the leading cause of bacteremia with resistance to commonly prescribed antibiotics.
