“新的”传染病包括:弯曲杆菌肠炎、贾第虫病、退伍军人病、原发性阿米巴脑膜脑炎和病毒性出血热。医院内的B族链球菌感染、肠道病毒感染以及其他一些感染也是近年认识的。现分别叙述如下。弯曲杆菌肠炎直到70年代,弯曲杆菌才被认为是一类引起牛和其他动物腹泻,以及偶尔引起人类菌血症的弧菌。在发现空肠/结肠弯曲杆菌(胎儿弯曲杆菌空肠亚种)引起人的腹泻,并且发展了简便的实验鉴定技术后,这种细菌便成为散发急性腹泻最常见的致病菌(约占5%)。目前,每周向传染病监察中心报告的弯曲杆菌肠炎为200例。由于常规检 “New” infectious diseases include: Campylobacter enteritis, giardiasis, veteran disease, primary amoebic meningoencephalitis and viral hemorrhagic fever. In the hospital, Group B streptococcal infections, enterovirus infections and other infections are also recognized in recent years. Now are described as follows. Campylobacter coli Until the 1970s, Campylobacter was considered a type of vibrio that causes diarrhea in cattle and other animals, and occasionally causes human bacteremia. After the discovery of jejunum / Campylobacter coli (Campylobacter fetus, Campylobacter jejuni) causes diarrhea and the development of a simple laboratory assay, the bacterium becomes the most common pathogen (about 5%) circulating acute diarrhea . Currently, Campylobacter enteritis is reported weekly to the Communicable Disease Surveillance Center for 200 cases. Due to routine inspection
