目的掌握马尾造船厂8大类医学媒介种群构成及分布,为口岸媒介防控提供依据。方法按《出入境检验检疫行业标准》,于2010年3月~2011年2月进行调查,鼠类用鼠笼法,肾综合征出血热抗原检测用间接免疫荧光法,鼠疫抗原检测用反向间接血凝法。结果全年共捕鼠形动物161只,鼠密度7.2%,臭鼩鼱为优势种;鼠肺检测肾综合征出血热抗原126份,阳性5份(4.0%),阳性鼠主要为褐家鼠;鼠肝检测鼠疫抗原均阴性。全年捕获蝇类13 463只,密度384.7只/笼·日;螨类96只,鼠体总染螨率3.1%;蜱类11只,鼠体总染蜱率2.5%;蚊117只,成蚊平均密度为4.9只/人;蜚蠊115只,密度为0.2只/盒。结论鼠、蚊、蝇等密度超标,需在高峰季节采取控制措施;在鼠体上截获肾综合征出血热病原,应重视鼠密度和HFRSV病毒的检测,随时掌握其鼠间及人群HFRS流行动态。
Objective To understand the composition and distribution of eight types of medical media in Mawei Shipyard, and to provide a basis for prevention and control of port media. Methods According to “Entry-Exit Inspection and Quarantine Standards”, from March 2010 to February 2011 to investigate the murine squirrel cage, hemorrhagic fever with renal syndrome antigen detection by indirect immunofluorescence, plague antigen detection with the reverse Indirect hemagglutination. Results A total of 161 mouse-shaped animals were captured in the year, with a density of 7.2% and a dominant species of stinky smelt. In the rat lungs, 126 samples of hemorrhagic fever with renal syndrome were detected, and 5 were positive (4.0%). ; Rat liver test plague antigen negative. In the year, 13 463 flies were caught, with a density of 384.7 / cage · day; 96 mites, the total rate of mites in the mice was 3.1%; that of the ticks was 11 in the whole population; The average density of mosquitoes was 4.9 / person; 115 cockroaches, the density of 0.2 / box. Conclusions Excessive density of rats, mosquitoes and flies may require control measures during peak season. Intercepting hemorrhagic fever with renal syndrome in mice should pay attention to the detection of murine densities and HFRSV virus, keep an eye on the prevalence of HFRSV .
