【摘要】：目的调查昆明、大理和景洪市售的食用螺类感染广州管圆线虫情况,探索和建立广州管圆线虫病防控机制。方法于2009-2014年每月2次对昆明、大理、景洪市场出售的食用福寿螺、圆田螺进行定点监测。每点采集福寿螺和圆田螺各50只以上,采用肺检法和均浆法剖检采集的螺类,统计广州管圆线虫感染情况。结果采集昆明、大理和景洪三地农贸市场销售的螺类51 693只,广州管圆线虫感染195只,感染率为0.38%。中华田园螺和铜绣环棱螺分别检测2 030和683只,未检出广州管圆线虫阳性螺;检测福寿螺48 980只。螺类以2011年感染率最高,为0.55%(68/12441),2012年感染率最低,为0.21%(19/9 164),不同年份感染率间差异有统计学意义(χ2=9.66,P0.05)。全年均可检出广州管圆线虫感染螺类,不同季节感染率间差异有统计学意义(χ2=76.87,P0.05)。2009-2014年间共报告广州管圆线虫病病例112例,疑似病例62例,临床诊断病例50例;112例病例中大理州报告44例、昆明市报告19例、景洪市报告49例;大理和昆明共处置3起广州管圆线虫病暴发疫情,报告病例17例,无重症和死亡病例。结论昆明市、大理市和景洪市农贸市场销售的福寿螺有广州管圆线虫感染,存在食品安全风险,应加强市场食品卫生的监督和健康教育以减少广州管圆线虫感染。
[Abstract]:Objective to investigate the infection of nematodes cantonensis by edible snails sold in Kunming, Dali and Jinghong markets, and to explore and establish the prevention and control mechanism of nematode cantonensis. Methods from 2009 to 2014, the edible snails and Oncomelania hupensis sold in Kunming, Dali and Jinghong markets were monitored twice a month. More than 50 snails were collected at each point, and the snails collected by lung examination and homogenization method were examined by lung examination and homogenization method, and the infection of Oncomelania cantonensis was counted. Results 51 693 snails were collected from Kunming, Dali and Jinghong farmers' markets, 195 of them were infected with C. cantonensis, the infection rate was 0.38%. Chinese pastoral snail and copper embroidered ring snail were detected in 2030 and 683 respectively, no positive snails were detected, and 48980 snails were detected. The infection rate of snails was the highest in 2011 (0.55%) and the lowest in 2012 (0.21%) (19%). There was significant difference in the infection rate among different years (蠂 2 鈮，
