摘　　要：目的了解厌氧血培养病原菌的分布情况,并分析厌氧菌败血症的主要特点。方法对2010年1月-2013年11月本院厌氧血培养结果进行回顾性调查。结果 36 211份厌氧血培养中共分离到兼性厌氧菌2 108株,检出率为5.82%;专性厌氧菌109株,检出率为0.30%。2 108株兼性厌氧菌中,革兰阳性球菌1 258株,占59.68%;革兰阴性杆菌803株,占38.09%;革兰阳性杆菌37株,占1.76%;真菌10株,占0.47%。109株专性厌氧菌中,分离率前3位的分别是厌氧消化链球菌(12.84%)、脆弱拟杆菌(9.18%)和梭状梭菌(8.26%)。厌氧菌败血症患者主要分布在新生儿科(33.94%)、产科(11.93%)和消化内科(7.34%)。易合并肺炎、肺脓肿和休克是厌氧菌败血症的主要特点。结论开展厌氧血培养,对疾病进行及时正确的诊断和治疗,对提高患者治愈率有重要作用。Objective To investigate the distribution of pathogens in anaerobic blood culture and analyze the major characteristics of anaerobic septicemia. Methods To retrospectively analyze the results of anaerobic blood culture from January 2010 to November 2013 in this hospital. Results 2 108 strains of facultative anaerobic bacteria were isolated from 36 211 cases of anaerobic blood culture,with the positive rate of 5. 82%; 109 strains were obligate anaerobes,with the positive rate of 0. 30%. In the 2 108 strains of facultative anaerobic bacteria,1 258 strains were gram positive bacteria,accounting for 59. 68%; 803 strains were gram negative bacteria,accounting for 38. 09%; 37 strains were gram positive bacteria,accounting for 1. 76%; 10 strains were fungi,accounting for 0. 47%. The separation rates of Peptostreptococcus anaerobius（ 12. 84%）,Bacteroides fragilis（ 9. 18%） and Clostridium clostridioforme（ 8. 26%） were the top 3 pathogens in the 109 strains of obligate anaerobes. Patients with anaerobic septicemia mainly distributed in neonates ward（ 33. 94%）,department of obstetrics（ 11. 93%） and digestive system department（ 7. 34%）. Pneumonia,lung abscess and shock were the main complications of anaerobic septicemia. Conclusion Develop anaerobic blood culture,and to diagnose and treat the diseases in a timely and correct manner,which play a significant role in proving the cure rate of the patients.
