目的了解松阳县并殖吸虫病疫源地现状和人群流行情况,为并殖吸虫病的预防控制提供依据。方法选择3个山区乡(镇)3个村作为调查点,每点调查第二中间宿主溪蟹50～100只,采用捣碎沉淀法和心脏检测法分别检测溪蟹肌肉和心脏囊蚴感染情况;随机选取100～150人进行吃蟹方式调查,采集被调查者血清,ELISA检测并殖吸虫血清抗体。结果第二中间宿主溪蟹检出卫氏并殖吸虫和三平正并殖吸虫2种囊蚴,捣碎沉淀法检测154只溪蟹,肌肉中并殖吸虫囊蚴感染率为57.79%,心脏检测73只,囊蚴感染率为57.53%;人群血清并殖吸虫抗体检测379人,阳性17人,阳性率4.49%;人群吃蟹方式调查379人,133人有生食溪蟹习惯,生食率35.09%。结论松阳县属于卫氏并殖吸虫和三平正并殖吸虫混合流行区,应在山区人群中开展并殖吸虫病防治的健康教育工作,纠正生食或半生食溪蟹的不良生活习惯。
Objective To understand the prevalence and prevalence of paragonimiasis in Songyang County and provide evidence for the prevention and control of paragonimiasis. Methods Three villages (towns) in three townships were selected as survey sites. Fifty to 100 crab crabs were investigated at each site. The infection of crab muscle and cardiac metacercaria in crabs was detected by mashed sedimentation method and heart detection method ; Randomly selected 100 to 150 people to eat crabs survey, the sera collected from the respondents, ELISA test Paragonimus serum antibodies. Results The second intermediate host, crab and crab, detected two metacercariae of Paragonimus westermani and Paragonimus spp., And detected 154 crabs by the method of crushing and sedimentation. The infection rate of Paragonimus muscle in the muscle was 57.79% 73, the infection rate of metacercaria was 57.53%; 379 were tested for paragonimiasis seropositivity in the population, 17 were positive, the positive rate was 4.49%; 379 were surveyed by the population, 133 were raw crab habit, the raw food rate was 35.09% . Conclusion Songyang County belongs to the mixed prevalence area of Paragonimus westermani and Paragonimus spp., And health education should be carried out in the mountainous area to prevent and control the diseases of paragonimiasis, so as to correct the unhealthy habits of raw and half raw crabs.
