【摘要】 目的为了进一步摸清和掌握我区鼠疫疫情现状,为我区制定鼠疫防治措施提供科学依据。方法宿主动物家鼠密度采用笼捕法,以20×10×10cm的铁丝笼为捕鼠器,以鲜地瓜为诱饵捕捉活鼠,每年连续监测6个月,每月布放3个晚上,晚放晨收。媒介昆虫鼠体蚤检集,将捕获的老鼠分别装袋,用乙醚麻醉后检蚤;游离蚤用粘蚤法检集。结果捕鼠4种计477只,鼠密度为5.47%。主要是黄胸鼠占47.17%。鼠体蚤、染蚤鼠271只,染蚤率56.81%,染蚤率最高是褐家鼠65.27%。鼠蚤指数,检出4种蚤计1275个,其中印鼠客蚤720个,蚤指数1.51;黄胸鼠印鼠客蚤指数最高为1.77;游离蚤指数0.019。检测鼠肝、脾188份,用反向血凝阳性滴度试验均为阴性。鼠血清252份,用间接血凝试验检测抗体全部阴性。结论新罗区存在发生鼠间鼠疫的危险性,应加强监测,定期开展群众性的灭鼠灭蚤工作;防止鼠疫发生流行。更多还原

【Abstract】 Objective To feel out and understand current plague situation in our area,and to provide scientific reference for formulating prevention and control measures.MethodsWe adopted a cage to catch the rats to measure the density of rat host animal.It used an iron wire as mousetrap,which measured 20 × 10 × 10 centimeters,took fresh sweet potato as bait to catch the living rats,continuous monitoring for 6 months a year,3 cages were put every month which was put in the evening and collected in the morning.The insect vector rat body flea is detected and collected,bagged the captured rats respectively,detected flea after anaesthetizing the rats with ether;Detected dissociating flea by the method of sticky flea.Results4 kinds were captured,the number amounts to 477.Density of rat was 5.47%.Rattus flavipectus(黄胸鼠)took up 47.17% mostly.271 animals were found with fleas,the flea infection rate of rats was 56.81%.The maximum of flea inflection rate accounted for 65.27% of sewer rat.Four kinds of fleas were tested,with a total amount of 1275 in the rat flea index,among which the amount of xenopsylla cheopis(印鼠客蚤)was 720,flea index was 1.51;the max xenopsylla cheopis index of rattus flavipectus was 1.77;dissociating flea index was 0.019.188 samples of liver and spleen were tested,反向血凝阳性滴度 was not found.252 blood serum samples were tested,间接血凝 antibody was negative.ConclusionThere exists the danger of plague prevalence in Xinluo District.We should reinforce the monitoring,carry out rat and flea extermination with popularity at the regular intervals so as to prevent plague prevalence.更多还原
