ABSTRACT

Introduction: human immunodeficiency virus seropositive individuals are at high risk for developing a bloodstream infection.
Objective: to identify the etiologic agents and risk factors associated with this entity.
Methods: a prospective observational study was conducted from February to December 2012. The study group consisted of 118 patients. Microbial identification was performed by the VITEK 2 Compact automated system. Variables were calculated to determine the association between the prevalence ratio.
Results: predominance of male patients, aged 41-50 years, severely immunecompromised and undergoing antiretroviral therapy was observed. Enterobacter Staphylococcus aureus was the main isolated Gram-positive bacterium.
Conclusions: gram-negative bacteria are ratified as important causative agents of bacteremia in HIV/AIDS patients. The invasive procedures are major risk factors for the development of bacteremia in HIV positive patients.
