| Abstract: | Veillonella parvula and alcalescens are anaerobic gram-negative cocci that, when isolated from anaerobic cultures of clinical specimens, are usually regarded as commensal organisms. Occasionally they play a pathogenic role and require antibiotic therapy. Limited clinical experience and in vitro susceptibility studies suggest that penicillin G is the drug of choice for these organisms and that cephalosporins, clindamycin, chloramphenicol, and metronidazole may be acceptable therapeutic alternatives. Presented herein is a case report of a Veillonella infection, a discussion of the importance of these organisms when they occur in a clinical infection, and a discussion of the appropriate antibiotic therapy. |
