We report 56 episodes of bacteremia and fungemia in 45 patients (23%) out of overall 193 cases of AIDS. 41% of the isolates were gram-negative bacilli, with a predominance of Salmonella enteritidis (30%), most of them community-acquired. Gram-positive cocci (18 episodes) were hospital-acquired in 61%, with a predominance of Staphylococcus sp (10 cases). Mycobacteria and Cryptococcus neoformans were isolated in 8 patients. 88.8% of our patients with cryptococcosis (8/9) had positive blood cultures. 76% of the episodes (43/56) were community-acquired, with a high incidence of primary bacteremias (59%). 48% of the patients were cured, whereas 27% died from causes related with the bacteremia.
