During the past two decades surveys have shown a reduction in the incidence of anaerobic infections. Possible explanations include the use of prophylactic antibiotics in bowel surgery and the widespread use of broad spectrum antibiotics.
This was a retrospective review of all blood cultures analysed by a US hospital microbiology laboratory over a three year period (1994 to 1996 inclusive).
Over the three year period, 6891 patient blood cultures were analysed. A total of 1626 patients tested positive for bacterial infection. Aerobic or fungal isolates accounted for 1590 patients. There were 36 anaerobic isolates but 28 of these were the result of contamination. Only seven patients had true anaerobic bacteraemia, all from an obvious source of anaerobic infection which could have been predicted clinically. One patient's data were unavailable for analysis.
