厌氧菌为感染性疾患的常见和重要的致病菌[1～6]。我院213份外科感染的脓液标本中,无芽胞厌氧菌阳性率为52.1%。膈下脓肿、阑尾和肛旁脓肿、腹内其他脓肿的致病菌中,无芽胞厌氧菌分别为90.9%、77.8%、55.6%。由此可见,无芽胞厌氧菌引起的外科感染远高于一般需氧茵,值得外科医师予以(?)视。特别是10.3%仅培养出无芽胞厌氧菌,这些标本如仅作需氧菌培养,就会被误认为“无菌感染”或 Anaerobic bacteria are common and important pathogens of infectious diseases [1-6]. 213 cases of surgical infection in our hospital pus specimens, non-spore anaerobic bacteria positive rate was 52.1%. In the subphrenic abscess, appendix and perianal abscess, intraabdominal abscess other pathogenic bacteria, non-spores anaerobic bacteria were 90.9%, 77.8%, 55.6%. Thus, the surgical infection caused by non-spore-forming anaerobic bacteria is much higher than the general aerobic, it is worth to the surgeon to (?) Visual. In particular, only 10.3% of non-spore-forming anaerobes are cultivated. These specimens, if grown aerobically, are mistaken for “aseptic infection” or
