摘要目的 了解和分析南昌市人体寄生虫病的流行现状,为制订南昌市寄生虫病防治措施提供科学依据.方法 2014年,按照《全国第3次人体重点寄生虫感染现状调查方案》,在南昌市选择进贤县、安义县、青云谱区和青山湖区对常住居民进行肠道寄生虫调查,包括土源性线虫(蛔虫、鞭虫和钩虫)、蛲虫、带绦虫和肠道原虫;在青云谱区和青山湖区对常住居民进行华支睾吸虫调查;在南昌县、新建县2个农村地区和东湖区、西湖区2个城区,对居民进行弓形虫调查.土源性线虫、华支睾吸虫、带绦虫等蠕虫虫卵检查采用改良加藤厚涂片法,儿童蛲虫检查采用透明胶纸肛拭法,肠道原虫滋养体或包囊检测采用生理盐水涂片法和碘液涂片法,弓形虫IgG抗体检测采用酶联免疫吸附测定法(ELISA).结果 全市肠道寄生虫共调查了2424人,其中2414人接受了土源性线虫和带绦虫调查,1875人接受了肠道原虫检查,74名儿童接受了透明胶纸法蛲虫卵检查;华支睾吸虫共检查了539人;弓形虫共检查了2400人.全市共查出肠道寄生虫6种,感染率为9.49%(230/2424).土源性线虫感染率为8.70%(210/2414),其中蛔虫感染率为0.04%(1/2414)、 鞭虫感染率为0.91%(22/2414)、钩虫感染率7.83%(189/2414).3~6岁儿童蛲虫感染率为22.97%(17/74),带绦虫和华支睾吸虫感染率为0,肠道原虫感染率为0.21%(4/1875),弓形虫IgG抗体阳性率为5.17%(124/2400).结论 南昌市人群土源性线虫(蛔虫、鞭虫)和肠道原虫感染率较低,但钩虫、弓形虫和3~6岁儿童蛲虫感染率较高,是南昌市今后寄生虫病防治工作的重点.

abstractsObjective To understand and analyze the infection status of human parasites in Nanchang City, so as to offer a scientific basis for control of parasitic disease. Methods In 2014, a survey was performed according to the scheme of "The 3rd National Survey of Principal Human Parasites". Intestinal parasites were surveyed among the residents in Jinxian County and Anyi County, Qingyunpu District and Qingshanhu District in Nanchang City, including the soil-transmitted nematodes (Ascaris lumbricoides, Trichuris trichiura and hookworm), Enterobius vermicularis, tapeworm and intestinal protozoa. Clonorchis sinensis was surveyed among the residents in Qingyunpu District and Qingshanhu District. Toxoplasma gondii was surveyed among the residents in two rural areas (Nanchang County and Xinjian County) and two urban areas (Donghu District and Xihu District). The ovums of the soil-transmitted nematodes, Clonorchis sinensis , tapeworm and other helminths were examined by the Kato-Katz, while Enterobius vermicularis among children was examined by cellophane anal swab, trophozoites and cysts of intestinal protozoa by saline smearing and iodine smearing , and IgG antibodies of Toxoplasma gondii by enzyme-linked immunosorbent assay (ELISA). Results Intestinal parasites were surveyed among 2424 residents in the whole city, in which 2414 residents were tested for the infection of soil-transmitted nematodes and tapeworm;1875 residents were tested for intestinal protozoa infection;74 children were tested for eggs of Enterobius vermicularis; 539 residents were tested for Clonorchis sinensis; and 2400 residents were tested for Toxoplasma gondii. Six kinds of intestinal parasites were found citywide, with a total infection rate of 9.49% (230/2424). The infection rate of soil-transmitted nematodes was 8 . 70% ( 210/2414 ) , in which the infection rate of Ascaris lumbricoides was 0.04% (1/2414), the rate of Trichuris trichiura was 0.91% (22/2414), and of hookworm was 7.83%(189/2414). The infection rate among 3 - 6 years old children of Enterobius vermicularis was 22.97% ( 17/74 ) . Tapeworm and Clonorchis sinensis were not found . The infection rate of intestinal protozoa was 0.21%(4/1875). The positive rate of Toxoplasma gondii's IgG antibody was 5.17% (124/2400). Conclusions In Nanchang City, the infection rate of soil-transmitted nematodes (Ascaris lumbricoides, Trichuris trichiura) and intestinal protozoa was lower. However, the infection rates of hookworm, Toxoplasma gondii and Enterobius vermicularis among 3 - 6 years old children are increasing in local areas. That should be the focus in prevention and control of parasitic disease in the future.
