Aerobic, facultatively anaerobic, and obligately anaerobic gram-negative bacteria have been isolated from 10% to 40% of cases of prosthetic valve endocarditis. Such isolates have included Proteus, Escherichia coli, Serratia marcescens, Klebsiella pneumoniae, Enterobacter, Salmonella, Haemophilus, Achromobacter, Acinetobacter calcoaceticus, Alcaligenes faecalis, Actinobacillus actinomycetem-comitans, Eikenella corrodens, Brucella, Cardiobacterium hominis, Neisseria, and Bacteroides fragilis (1, 2).
