Cases of @entity2259 caused by anaerobic microorganisms and occurring during a four year period in a non-selected @entity1 group in a Spanish general hospital were analysed retrospectively. Microbiological data was collected on 212 @entity1 and clinical data on 103 @entity1 . Cases of anaerobic @entity2259 represented 8.6% of the total number of cases of @entity2259 . Of the 232 anaerobic microorganisms causing @entity2259 , gram-negative bacilli were responsible in 113 cases (48.7%), gram-positive bacilli in 92 cases (39.6%), gram-positive cocci in 25 cases (10.7%), and Veillonella @entity5645 . in two cases (0.8%). The most important clinical features were @entity221 (64%), @entity417 (56%), @entity326 (22%) and metastatic abscesses (21%). @entity1 with anaerobic @entity2259 were hospitalized for an average of 51.7 days. The overall mortality was 32% and factors associated with poor prognosis were severe underlying disease, nosocomial acquisition, presence of shock, presence of metastatic foci of @entity281 , and absence of adequate surgical drainage. The mortality rate of @entity1 who received adequate antimicrobial therapy was 30% and that of @entity1 who received inadequate treatment or none was 29%. It is concluded that anaerobic @entity2259 has a significant rate of morbidity and mortality and that underlying disease and surgical debridement and/or drainage have greater prognostic significance than the use of antimicrobial agents.
