[Microbiology and management of gaseous gangrene:the Sichuan experience of 20 earthquake cases].

Wound secretion from 20 patients with gaseous gangrene was collected for Gram staining, bacterial culture and drug sensitivity tests. The results indicated that gaseous gangrene was caused by the co-infection of both aerobic and anaerobic bacteria. Gram-negative bacilli were slightly more common than other aerobic bacteria in gaseous gangrene wound, which was different from the findings of ordinary gaseous gangrene.
