%X bacteremia is an important cause of morbimortality. this study describes the episodes of community-acquired bacteremia in adult patients registered at our hospital. between january 2005, and december 2009, 271 episodes were studied. the diagnostic yield of blood cultures was 13.5 %. a total of 52 % of patients were male and 48 % female. the mean age was 60. the most frequent comorbidities were: diabetes (21 %), neoplasia (18 %), cardiopathy (11 %), and hiv infection (8 %). the focus was- respiratory (21 %), urinary (15 %), cutaneous (9 %), and others (13 %). gram-positive bacteria prevailed (51.4%). the most frequent microorganisms were escherichia coli (25 %), streptococcus pneumoniae (22.9 %), and staphylococcus aureus (12.3 %). bacteremia was polymicrobial in 7 % of the cases. thirty three percent of e. coli isolates were resistant to ciprofloxacin and 6 % to ceftazidime. fourteen percent of s. aureus strains were resistant to oxacillin whereas only 7 % of s. pneumoniae expressed high resistance to penicillin with mics = 2 ug/ml, according to meningitis breakpoints.
