近10年来发现4种重要的胃肠道特异性感染：1．梭形芽胞杆菌感染：抗素菌引起急性非特异性假膜性结膜炎，目前认为与校形芽胞杆菌感染后产生的毒素有关。本病诊断依据大便分离出细菌和它的毒素。口服万古霉素125—500mg每6小时一次，常常有效。梭形芽胞杆菌感染尚可加重或激发慢性肠道疾病如溃疡性结肠炎和Crohn’s病。作者认为对每例弥散性结肠炎病人均应考虑此菌感染的可能性。 In the past 10 years, four important gastrointestinal tract-specific infections have been found: 1. Fusobacterium infection: Antibiotics cause acute nonspecific pseudomembranous conjunctivitis and are currently thought to be associated with toxins produced by Bacillus coli. The diagnosis of this disease based on stool isolated bacteria and its toxins. Oral vancomycin 125-500mg every 6 hours, often effective. Fusobacterium infection can still aggravate or stimulate chronic intestinal diseases such as ulcerative colitis and Crohn’s disease. The authors believe that every case of patients with diffuse colitis should consider the possibility of infection of the bacteria.
