Background: Bacterial bloodstream infections are important opportunistic infections which causernhigh morbidity and mortality among HIV infected individuals. Bacterial bloodstream infectionsrnamong HIV/AIDS Patients in Ethiopia is poorly known. Therefore, determining the etiologicalrnagents of bacterial bloodstream infections and their in vitro antimicrobial susceptibility patternrnamong HIV infected patients in Ethiopia is one of the highest priorities.rnObjective: The aimed of this study was to determine the extent of bacterial bloodstream infectionsrnand their in vitro antimicrobial susceptibility pattern among HIV/AIDS patients attending ART-rnclinic from July 15, 2016 to December 15, 2016 G.C at Felege Hiwot Referral Hospital, Bahir Dar,rnAmhara National Regional State North West Ethiopia.rnMethods and Materials: A hospital based cross sectional study was conduct among 384rnHIV/AIDS patients attending ART- clinic at Felege Hiwot Referral Hospital during the studyrnperiod. Venous blood samples were collected under strict aseptic condition. Collected bloodrnsamples were inoculated on blood culture bottles and incubated aerobically at 37o c for seven daysrnfor the presence of visible sign of microbial growth. Sub cultures were done on the BAP, CAP andrnMAC (Oxoid). Microorganisms were isolated and identified using standard biochemicalrntechniques. Antimicrobial susceptibility tests for each isolated bacteria were determined by discrndiffusion method. Quality of the data was assured through standard operational procedures (SOPs).rnData was entered, checked for completeness and analyzed using SPSS version 20.rnResult: This study confirmed that among HIV/AIDS patients, 123 (32%) were infected withrnbacteremia. Prevalence of blood stream infection was higher in 1-14 years of age group (53.8%)rnthan other age group. Higher percentage of positive blood culture isolates among HIV/AIDSrnpatients having CD4 count of
