Background: Nontyphoidal Salmonella bacteria have emerged as the prominent cause of severe and life-threatening bacteremia in HIV-infected patients. Antimicrobial resistance is another concern that adversely affects the health outcome of the patients. This study investigated the prevalence, antimicrobial susceptibility pattern of the isolates, and associated factors of nontyphoidal Salmonella bacteremia among antiretroviral therapy-naïve HIV-infected adult individuals at three public hospitals in Eastern Ethiopia.
Methods: A cross-sectional study was conducted among 170 antiretroviral therapy-naïve HIV-infected adult individuals in three public hospitals in Eastern Ethiopia from June 2017 to June 2018. Data on sociodemographic and associated factors were collected using a pretested structured questionnaire. Blood specimens were examined for nontyphoidal Salmonella using the recommended culture and serological methods. Data were analyzed using the Statistical Package for Social Sciences version 20.0. Bivariate and multivariate logistic regression models were used to identify the predictors of nontyphoidal Salmonella bacteremia. A P-value
Results: The prevalence of nontyphoidal Salmonella bacteremia was 10% (95% CI: 5.93–15.54). A lack of hand washing habit before food preparation (adjusted odds ratio [AOR]: 13.1, 95% CI: 10.40–15.30) and a CD4+ count
Conclusion: The prevalence of nontyphoidal Salmonella bacteremia was high. HIV-infected patients who did not wash their hands before food preparation and those whose CD4+ count was
