一、病源1906年后,百日咳的病源已被证实为百日咳嗜血杆菌Bordetella Pertussis.副百日咳杆菌B.Parapertussis及支气管腐败杆菌B·Bronchi-septica则引起副百日咳.既往认为百日咳、副百日咳为两种截然不同的疾病,但除了副百日咳的临床表现较短外,两者不易区别.近年来由于从百日咳杆菌中分离出噬菌体,此噬菌体可使副百日咳杆菌转换为百日咳杆菌,故认为副百日咳杆菌实际为百日咳杆菌的无毒株,百日咳和副百日咳均由百日咳杆菌所引起.1932年以后发现某些病毒如巨细胞病毒、呼吸道合胞病毒、副流感病毒、肠道病毒、尤其是腺病毒也可引起百日咳类似的临床症状和X光表现,其病程和病理变化与典型百日咳难以鉴别,唯有通过病原学和血清学检查才能区分,这部分约占百日咳病例的20%,所有这些能引
First, the source of the disease after 1906, the source of pertussis has been confirmed as Bordetella Pertussis Bordetella Pertussis B. parapertussis B. bronchiseptica and Bacillus bronchiseptica is caused by the second whooping cough in the past that pertussis pertussis two A very different disease, but in addition to the clinical manifestations of pertussis pertussis short, the two are not easy to distinguish in recent years due to the isolation of the bacteriophage from Bordetella pertussis, this bacteriophage can pass B. pertussis into Bordetella pertussis, so that B. pertussis actual It is a non-virus of Bordetella pertussis, whooping cough and parathion pertussis are caused by Bordetella pertussis.After 1932 some viruses such as cytomegalovirus, respiratory syncytial virus, parainfluenza virus, enterovirus, especially adenovirus can also be found Causing pertussis similar clinical symptoms and X-ray findings, its course and pathological changes and typical whooping cough is difficult to distinguish, only through etiology and serological tests to distinguish, this part of the pertussis accounts for about 20% of all cases, all of these can lead
