ABSTRACT
Objective To investigate the deep ulcer infection of anaerobic bacteria in patients with diabetic foot ,while make clini-cal value analysis .Methods 87 specimens collected from the patients with deep ulcers of diabetic foot were performed by bacterio-logical smear and bacterial culture respectively .Results The bacteriological smear positive cases were 81 ,the aerobic culture posi-tive cases were 67 and the anaerobic culture positive cases were 17 .Conclusion The deep ulcers of diabetic foot often are infected by anaerobic bacteria .Aerobic culture and anaerobic culture are both necessary to define the pathogen .It must be noted that the an-aerobic culture positive rate would be interfered by incorrect sampling ,no timely examination ,using antibiotics and incorrect culture conditions .
