ABSTRACT
MICROBIOLOGY Several studies have provided insight into the role of anaerobic bacteria in the etiology of infected tumor mass indirectly through the administration of antimicrobial agents.2-7 However, the microbiology of infected tumors was not established in these studies. Rotimi and Durosinmi-Etti8 found anaerobes to be the predominant organisms recovered from 10 patients with infected malignant ulcers. Of a total of 282 bacteria isolates, anaerobic bacteria accounted for 179 (63%).
