摘　　要：①目的　探讨肛周脓肿厌氧与需氧菌的菌群分布。②方法　选择 31例肛周脓肿患者 ,对其脓液中的厌氧菌和需氧菌进行培养鉴定。③结果　肛周脓肿感染患者中男 2 7例 ,女 4例 ;感染者中共分离出 51株细菌 ,其中厌氧菌 30株 ,需氧菌 2 1株。厌氧菌总检出率为 96 .8% ,需氧菌总检出率为 67.4%。单纯厌氧菌感染检出率为 32 .3 % ,单纯需氧菌检出率为 3 .2 %。厌氧和需氧菌混合感染检出率为 64 .5 %。在所分离出的 30株厌氧菌中 ,脆弱类杆菌占 80 % ,消化链球菌占 1 3 % ,普通类杆菌和产黑色素类杆菌各占 3 .3 %。 2 1株需氧菌中 ,大肠杆菌占 71 % ,肺炎克雷伯菌、产气肠杆菌、阴沟肠杆菌各占 9.5 %。④结论　肛周脓肿男性患病率高于女性 ;细菌感染菌群分布以脆弱类杆菌和大肠杆菌为主 ;Objective To study the distribution of anaerobes and aerobes in perianal abscess.Methods 31 specimens were taken from the perianal abscess, cultured and identified. Results 51 strains were isolated,including 30 strains anaerobes and 21 strains aerobes. Total isolated rate of anaerobes were 96.8%(30/31),aerobes were 67.4%(21/31).In which,the only anerobic positive were 32.3%(10/31), aerobic positive were 3.2%(1/31),both positive were 64.5%(20/31).In the 30 strains of anaerobes ,80%(24/30)showed B.fragilis, 13%(4/30) showed Pst. anaerobies, and 3.3%(1/30) showed B.vugatus or B.meraminogeniaes positive.In 21 strains aerobic bacteria ,71%(15/21) showed E.coli positive,9.5%(2/21) showed K.pneumoniae, E.aerogenes, E.cloacae positive.Conclusion The main infection bacteria were B.fragilis and E.coli.Mixed infection of anaerobic and aerobic were more often infectious type.
