目的了解罗湖区不同生境鼠的广州管圆线虫感染情况,为该区广州管圆线虫病防治和食品安全工作提供依据. 方法在杂草丛、花苗圃和住宅小区诱捕鼠类,采用股动脉放血法杀鼠,在鼠肺中查找广州管圆线虫成虫,计算并比较不同生境、种类、季节和性别鼠类的感染率差异. 结果共诱捕195只活鼠,其中褐家鼠、黄胸鼠、臭鼬与施氏屋顶鼠分别为124、17、50、4只,查出感染性褐家鼠21只,感染率为16.9％,其它鼠类未见感染.杂草丛中褐家鼠感染率为27.9％ (12/43),高于花苗圃的21.4％ (9/42)和住宅小区(0),差异有统计学意义(x2=12.23,P＜0.05).春、夏、秋、冬季褐家鼠感染率分别为18.8％ (3/16)、12.5％ (6/48)、18.0％ (9/50)、30.0％ (3/10),差异无统计学意义(x2=2.19,P＞0.05);雌、雄鼠感染率分别为13.1％ (8/61)和20.6％ (13/63),差异无统计学意义(x2=1.25,P＞0.05). 结论罗湖区褐家鼠广州管圆线虫感染率较高,存在疫情发生的可能性.

Objective To understand the status of Angiostrongylus cantonensis infection in rodents from different habitats in Luohu District,so as to provide scientific basis for angiostrongyliasis prevention and food safety.Methods The rodents at grassclusters,nurseries and residential areas were captured,then they were killed by bloodletting from arteria cruralis.The lungs of the rodents were taken out and checked for the adults of Angiostrongylus cantonensis.Finally the infection rates of rodents were compared among different habitats,species,gender and seasons.Results Totally 195 living rodents were captured and examined,among which Rattus norvegicus,Rattus flavipectus,skunk and Rattus rattus sladeni were 124,17,50,4,respectively.A total of 21 Rattus norvegicus was infected,with an infection rate of 16.9％(12/43),and no infected cases could be found in other three species of rodents.The infection rate of Rattus norvegicus from grassclusters was 27.9％(9/42),which was higher than those from nurseries[21.4％(9/42)] and residential areas (0),the difference was statistically significant (x2=12.23,P＜0.05).The infection rates of rodents captured in spring,summer,autumn and winter were 18.8％ (3/16),12.5％ (6/48),18.0％ (9/50),30.0％ (3/10),respectively,and there was no significant difference among them(x2=2.19,P＞0.05).The infection rates in male and female Rattus norvegicus were 13.1％ (8/61) and 20.6％ (13/63),respectively,the difference was not statistically significant (x2=1.25,P＞0.05).Conclusions Angiostrongylus cantonensis infection rate of rodents in Luohu District is high,and it is possible that the endemic situation occurs in the district.
