【摘要】：目的摸清開(kāi)江縣易感人群和中間宿主肺吸蟲(chóng)感染情況,為防制提供科學(xué)依據(jù)。方法 2013年9-10月,在開(kāi)江縣歷年有肺吸蟲(chóng)病病例的沙壩鄉(xiāng)抽取小學(xué)生和村民,采血檢測(cè)肺吸蟲(chóng)抗體;捕捉釘螺和螃蟹分別檢測(cè)肺吸蟲(chóng)尾蚴及囊蚴。結(jié)果檢測(cè)440人,血清肺吸蟲(chóng)抗體陽(yáng)性的28人,陽(yáng)性率為6.36%。抗體陽(yáng)性率,男性為7.83%,女性為4.76%(P0.05);各個(gè)年齡組在0%~10.17%(P0.05)。檢測(cè)擬釘螺196只,檢出肺吸蟲(chóng)尾蚴的29只,感染率為14.80%;查出尾蚴共38條,釘螺感染度為0.19條。檢查螃蟹209只,檢出肺吸蟲(chóng)囊蚴的31只,感染率為14.83%,檢出囊蚴共71個(gè),螃蟹感染度為0.34個(gè)。調(diào)查的440人中,喝生水的占83.86%,玩螃蟹的占68.18%,吃螃蟹的占56.82%。生吃螃蟹者所占比例,為全部調(diào)查對(duì)象的10.91%,調(diào)查對(duì)象中肺吸蟲(chóng)血清抗體陽(yáng)性者所占比例,生吃螃蟹者為16.67%和半生吃螃蟹者的10.22%,顯著高于熟吃和不吃螃蟹者的0.49%(P0.01);喝生水者為7.32%與不喝生水者的1.41%無(wú)統(tǒng)計(jì)學(xué)意義(P0.05);玩螃蟹者為8.33%高于不玩螃蟹者為2.14%(P0.05)。結(jié)論開(kāi)江縣為肺吸蟲(chóng)病低流行區(qū),肺吸蟲(chóng)感染主要是生吃和半生吃螃蟹所致。
[Abstract]:Objective to investigate the infection of paragonimiasis in susceptible population and intermediate host in Kaijiang County, and to provide scientific basis for prevention and control. Methods from September to October, 2013, primary school students and villagers were selected from Shaba Township with paragonimiasis cases in Kaijiang County, and blood samples were collected to detect paragonimiasis antibodies, and snails and crabs were captured to detect cercariae and cysticercariae, respectively. Results 440 patients were detected, 28 of them were positive for paragonimiasis antibody, the positive rate was 6.36. The positive rate of antibody was 7.83% in male and 4.76% in female (P0.05), and 10.17% in each age group (P0.05). 196 Oncomelania hupensis were detected and 29 cercariae of paragonimiasis were detected, the infection rate was 14.80 and 38 cercariae were detected, the infection degree of Oncomelania hupensis was 0.19. Of the 209 crabs, 31 were found to have paragonimiasis, the infection rate was 14.83, the cysticercaria was 71, and the infection degree of crab was 0.34. Of the 440 people surveyed, 83.86 drank raw water, 68.18 played with crabs and 56.82 ate crabs. The proportion of those who ate crab raw was 10.91.The proportion of those who had positive antibody to paragonimiasis serum was 16.67% and 10.22% of those who ate crab raw and those who ate crab half-raw were 16.67%, 10.22% and 10.22%, respectively. Significantly higher than cooked and not eating crab 0.49% (P0.01); There was no significant difference between those who drank raw water (7.32%) and those who did not drink raw water (1.41%) (P0.05), while those who played crabs were 8.33% higher than those who did not play crabs 2.14% (P0.05). Conclusion Kaijiang County is a low prevalence area of paragonimiasis. The infection of paragonimiasis is mainly caused by raw and semi-raw crabs.
