无芽胞厌氧菌,常常被人们认为是与临床无多大关系而又难以分离和鉴定的一群特殊细菌。直到最近,厌氧菌感染尚未引起注意。然而,如果对日益增多的内源性感染进行厌氧菌检查,则可以发现与厌氧菌有关的感染远比予想者多。如所周知,内源性感染的细菌是构成机体正常菌丛的细菌。肠道下段的厌氧菌比大肠杆菌及其他需氧、兼性厌 Aneurysm-free anaerobes are often thought of as a group of special bacteria that have little to do with clinical isolation and identification. Until recently, anaerobic infections have not attracted much attention. However, if anaerobic bacteria are tested for an increasing number of endogenous infections, more anaerobic infections may be found than expected. As is known, endogenous infected bacteria are bacteria that make up the body’s normal flora. Lower anaerobic intestinal than E. coli and other aerobic, facultative tired
