Most cases of anaerobic endocarditis are caused by anaerobic cocci, Propionibacterium acnes, and Bacteroides fragilis group (5). Owing to improvements in our ability to obtain and preserve anaerobic cultures, an increasing number of anaerobic bacteria have been isolated from PTA cultures, including Bacteroides fragilis and Bacteroides melaninogenicus, a common oral anaerobe. The human specific Bacteroides fragilis heat shock protein 40 (HSP40) bacteriophage has received some attention as a potential water quality indicator (118); however, further research is necessary to correlate presence of this virus in marine waters with specific public health risks. |
