厌氧菌864株的分离鉴定

总结三年来半对住院患儿多临床感染标本的厌氧培养，提高病原菌的检出率，应用ＡＰＩ２０Ａ鉴定系统对分离到的厌氧菌菌种进行鉴定，取２１０２份各种感染感染标本作厌氧培养，共分离出８６４株厌氧菌，经鉴定归１４个属，计５２个种，最常见的厌氧菌是革兰阴性杆菌，占阳性总数５３．９％（４６６／８６４），其次阳性球菌占２６．４％（２２８／８６４）阳性无芽胞杆菌，阴性球菌和阳性芽胞梭菌分别为１０．３％（８９／８６４）。

lsolation and identification of 864 anaerobes strains.

The pathogens of anaerobic culture of different kinds of clinical samples were detected from hospital children for three and a half years. Anaerobes isolated form anaerobic culture were identified using APl 20A System. There were 14 genus and 52 kinds of different anaerobes after identified the separated 864 anaerobes strain from anaerobic culture of 2102 infection samples. The most common anaerobes were gram negativ bacilli (53.9%), positive coccus (26.4%), positive no spore bacilli (10.3), negative coccus (7.8%) and positive clostridium (1.6%). The most common kinds of bacteria were Prevotella melaninogenica, Bacteroides fragilis and Peptostreptococcus anaerobius. To carry out anaerobic culture of different of infection samples could raise the levels of pathogenisis clinical diagnosis and treatment.
