目的了解兰州市蟑螂侵害和带菌状况,为开展蟑螂综合防制提供科学依据。方法采用目测法和药激法进行蟑螂侵害调查。现场捕捉活蟑螂送实验室,按常规检验方法进行细菌分离培养、血清学鉴定和生化试验,ELISA法检测HBsAg,饱和盐水悬浮镜检寄生虫卵。结果调查各类单位533家,蟑螂侵害率17.07%,超市、宾馆、餐饮和熟食加工店侵害率在19.13%～20.83%之间,医院、居民住宅和学校侵害率在9.52%～13.33%之间。检测蟑螂50组,细菌阳性40组,带菌率为80.00%。HBsAg检测阳性2组,带毒率4.00%;寄生虫卵检测阳性4组,带虫率8.00%。结论蟑螂侵害呈上升趋势,其传病作用和危害不可忽视。
Objective To understand the infestation and carriage of cockroaches in Lanzhou City and provide a scientific basis for the comprehensive prevention and control of cockroaches. Methods The investigation of cockroach infiltration was carried out by visual inspection and pharmacokinetics. Locate live cockroaches on the scene and send them to the laboratory. Bacteria isolation and culture, serological identification and biochemical tests are carried out according to routine test methods. HBsAg is detected by ELISA and parasite eggs are detected by saturated saline suspension microscopy. Results A total of 533 units of all kinds were investigated, with the infringement rate of cockroaches being 17.07%. The infringement rates of supermarkets, hotels, restaurants and cooked food processing shops ranged from 19.13% to 20.83%, and that of hospitals, residential houses and schools was between 9.52% ~ 13.33% . 50 cockroaches were detected, 40 were positive for bacteria, with a rate of 80.00%. HBsAg positive group 2, with a rate of 4.00%; parasite eggs were detected positive 4 groups, with a worm rate of 8.00%. Conclusion The cockroach infestation is on the rise, and its pathogenicity and harm can not be ignored.
