Anaerobic organisms in postoperative wounds

A survey of the bacteria found in postoperative wounds was undertaken during a 14-month period. The yields of aerobic and anaerobic bacteria in 65 appendicectomy wounds were compared; 42 wounds yielded aerobes and 51 anaerobes. Seventy-eight other operation wounds yielded anaerobes, and, overall, 33 wounds yielded anaerobes only. Bacteroides sp were the most common anaerobic organisms isolated from all operation sites except the lung.
