目前,对蟑螂传播疾病的机制研究已取得了一定的进展,认为机械携带病毒、细菌是传播疾病的重要方式,也有人认为蟑螂的排泄物是传播疾病的方式。我国南宁、福州、南京、株洲、哈尔滨等地的资料都有从自然界获取的蟑螂体内,体外检出了与人类相关的病源微生物的报导,哈尔滨、南通等地区通过人工感染的方法,从蟑螂体内,体外均检出乙肝表面抗原、黄曲霉菌,并观察到它们可在蟑螂体内能存活较长时间。为了解鼠伤寒沙 At present, the research on the mechanism of cockroach-borne diseases has made some progress. It is believed that the mechanical carrying of viruses and bacteria is an important way to spread the disease. Some people think that the cockroach’s excrement is the way to spread the disease. China’s Nanning, Fuzhou, Nanjing, Zhuzhou, Harbin and other places have obtained from the nature of cockroaches in vivo detection of human-related pathogens in vitro reports, Harbin, Nantong and other areas by artificial infection methods, from cockroaches in vivo Hepatitis B surface antigen, Aspergillus flavus were detected in vitro and it was observed that they could survive longer in cockroaches.
