The microbiology of mucopyocele.

Abstract

To evaluate the aerobic and anaerobic microbiology of mucopyocele. Retrospective review of clinical and microbiologic records of patients with mucopyocele between June 1982 and September 1997. Aspirates of 36 mucopyocele were processed for aerobic and anaerobic bacteria. One hundred six bacterial isolates, 42 aerobic and facultatives and 64 anaerobic, were recovered. The predominant aerobic isolates were Staphylococcus aureus (6 isolates), alpha-hemolytic streptococci (6), Hemophilus spp. (5), and Gram-negative bacilli (6). The predominant anaerobes were Peptostreptococcus sp. (22), Prevotella sp. (15), Fusobacterium sp. (5), and Propionibacterium acnes(5). Thirty-three beta-lactamase-producing bacteria were isolated from 23 patients. These findings illustrate the polymicrobial aerobic and anaerobic bacteriology of mucopyocele.
