目的了解漳州港招银港区开港以来鼠、蚤、螨类种群及其季节消长情况。方法于2000年5月至2001年4月对漳州港招银港区进行为期1年的鼠、蚤、螨类密度、种群及其季节消长的调查。结果捕获各种鼠类54只,经鉴定隶属2目2科3属4种,鼠类种群有褐家鼠,臭鼩鼱、黄胸鼠、小家鼠,其中褐家鼠为优势种群,占44.44%,其次为臭鼩鼱。全年平均鼠密度为4.5%,鼠密度该年度的高峰期为8、9、11月份。不同宿主动物的染蚤及革螨的情况不同,不同场所宿主动物的染蚤及革螨的情况也不同,且种类甚少,蚤类单一,只发现开皇客蚤,革螨类2种为纳氏厉螨和毒棘厉螨。应用冷冻切片免疫荧光法检测鼠肺流行性出血热病毒抗原37份,其中1份阳性,滴度为1:10。结论本次调查结果显示,漳州港招银港区的鼠种,以褐家鼠为优势种,其染蚤率高达29.41%,而且鼠类呈终年活动趋势,因此该地存在流行性出血热流行的危险。
Objective To understand the population dynamics of rodents, fleas and mites and their seasonal variations since the opening of Zhabei Port in Zhangzhou Port. Methods From May 2000 to April 2001, a one-year survey of the density, population, and seasonal variations of the mites, fleas and mites in Zhangzhou Port’s Zhabei Districts was conducted. Results A total of 54 species of rodents were captured. Four species belonging to 3 genera, 2 orders, 2 families were identified. Rattus norvegicus, Ranunculaceae, Rattus flavipectus, Mus musculus, 44.44%, followed by smelly 鼩 鼱. The annual average rat density was 4.5% and the rat density peaked at 8,9, and 11 months of the year. Different host animals infected with fleas and leather mites in different situations, different sites of host animals dyed fleas and leather mites are also different, and very few species, single flea, found only Kai Huang fleas, leather mites two kinds of Reichenry’s mites and spines and acarids. Immunofluorescence method was used to detect 37 samples of pulmonary hemorrhagic fever virus antigen in rat lungs, of which 1 was positive and the titer was 1:10. Conclusions The findings of this investigation show that the rodents in Zhaoyin Port Area of Zhangzhou Port are predominant species of Rattus norvegicus and their flea flea rate is as high as 29.41%, and the rodents are in the trend of annual activity. Therefore, there is epidemic of epidemic hemorrhagic fever danger.
