目的掌握阿拉山口口岸周边野外区鼠、蚤密度,种群构成、季节消长规律,为鼠情防制提供依据。方法于2006年4月-2007年3月使用板夹夹夜法和弓形夹夹捕法相结合对口岸野外区鼠情进行调查,并利用微量血凝法检测F1抗体及抗原。结果经过1年的监测,在口岸野外区共捕获鼠形动物279只,经过鉴定隶属2目4科6属8种。弓形夹捕获率为10.1%,捕获优势种为大沙鼠。板夹捕获率为1.8%,捕获优势种依次为子午沙鼠、红尾沙鼠和西伯利亚五趾跳鼠。分离鼠体表寄生蚤1539匹,优势种为臀突客蚤。血清学检测大沙鼠血清114份,检出F1阳性血清10份,阳性感染率为8.8%。结论对口岸野外区应重点加强在鼠、蚤活动高峰期对大沙鼠密度、染蚤情况及鼠疫血清学等方面的调查。由于子午沙鼠、红尾沙鼠等宿主动物经常参与大沙鼠鼠疫流行,因此也不能放松对这类宿主的监测。
Objective To understand the density, population composition and seasonal fluctuation of rat and flea around the Alashankou Port in order to provide basis for the prevention and control of rodent disease. Methods From April 2006 to March 2007, the boarding method was used to investigate the rodents in the field and the F1 antibody and antigen were detected by micro coagulation method. Results After one year of monitoring, 279 rat-shaped animals were captured in the field in the port area. Eight species belonging to 6 genera, 4 families, and 2 orders were identified. The capture rate of the arch clamp was 10.1%, capturing the dominant species as the gerbil. The capture rate of plate clip was 1.8%. The predominant species captured were Meriones unguiculatus, Red-tail Gerbil and Siberia Pentaptera. 1539 parasitic fleas isolated rat body, the dominant species of hip flea. Serological detection of 114 gerbils serum, detected F1 positive serum 10, the positive infection rate was 8.8%. Conclusion The investigation on the density, stained fleas and the serological aspects of the rat gerbil should be focused on the outdoor area of the port. Host animals such as Meriones unguiculatus and red-tailed goshawk are often involved in the epidemic of the large sand rat plague, and therefore monitoring of such hosts can not be relaxed.
