摘要
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, breeds composition of rat and fleas arid their seasonal fluctuation rule, provide available data for rat controlling. Methods Night wood trap and arch steel trap were used to capture rat, indirect hemagglutination assay (IHA) and reverse indirect hemagglutination assay (RIHA) were used to test F1 antibody and F1 antigen April 2006 through March 2007. Results 279 rodent animals were captured, and identified as 2 orders, 4 familifies, 6 genus and 8 species. Capture rate of arch steel trap is 10.1%, Rhombomys opimus is the dominant breed; Capture rate of night wood trap is 1.8%, main breeds are Meriones Meridianus, Meriones erythrourus and AUaltaga sibiraca. 1 539 rat parasitic fleas were found, Xenopsylla minax was main breed, i0 specimen of F1 antibody positive serum were found by IHA among 114 great gerbils serum, the positive rate is 8.8%. Conclusions Surveillance on great gerbils and on their fleas infection situation should be reinforced in areas around port, especially in the high density period of rat and fleas; Meriones meridianus and Meriones erythrourus were often found related with gerbils plague, so surveillance on them also is important.
