临沂市兰山区农村居民肠道寄生虫感染调查

目的 了解兰山区农村居民肠道寄生虫感染现状及防治效果。方法 采取改良加藤氏涂片法检查各种蠕虫卵，碘液直接涂片检查肠道原虫、滋养体和原虫包囊，透明胶纸拭法检查蛲虫的幼虫培养。结果 该区农村居民共感染7种肠道寄生虫，感染率为20．54％，其感染率分别是，蛔虫为7．28％(113／1653)，钩虫为0．45％(7／1563)，鞭虫为14．42％(224／1563)，华支睾吸虫0．06％(1／1563)，蛲虫为7．08％(16／226)，溶组织内阿米巴2．12％(11／518)，蓝氏贾第鞭毛虫2．51％(13／258)，从性别分布看，二者之间差异无显著性；从年龄分布看，5—9岁组感染率最高，为35．16％，次之为≥60岁和10—14岁组，成年人(≥20岁)感染率随年龄的递增而增高；从职业分布看，学生感染率最高，次之是农民；从家庭聚集性看，蛔虫、鞭虫等肠道寄生虫病有明显聚集性。结论 该区肠道寄生虫感染率较10年前有明显下降，说明近年来通过大规模的驱虫治疗取得了显著成绩，由于驱虫药物主要针对蛔虫，使蛔虫感染率下降较鞭虫快，从而出现鞭虫感染率明显高于蛔虫感染率。在今后防治工作中，应广泛进行宣传教育，增强农村居民卫生意识，提高自我保健能力。此外，有必要进行定期驱虫治疗来控制肠道寄生虫病的流行。

Survey on intestinal tract enterozoon infection among rural residents in Lanshan District of Linyi city

Objective ] To study the condition of intestinal tract enterozoon infection among rural residents and its prevention effect. Methods]All sorts of helminth eggs were tested by improved Teng smear technique, protozoons and trophozoite were tested by iodine smear techique, and the cultivation of larva was tested by cellophane swab. Results]Seven sorts of intestinal tract enterozoons were found among the rural residents with the infection rate of 20.54% . Among the enterozoons, lumbricoid was 7 .28 % (113/1653); hookworm 0.45 %(7/ 1563); whipworm 14.42% (224/2563); clonorchis sinensis 0.06% (1/1563); pinworm 7.08% (16/226) ; Entamoeba histolytica 2.12% (11/518); Giardia 2.51% (13/258) . According to sex, there is no significant difference between men and women; According to age, children aged from 5 to 9 are most easily infected (35.16% ) , next is the group aged from 10 to 14 and those older than 60. The possibility of infection among adults grows with the age; According to profession, the most easily infected people are students and then farmers; According to family, intestinal tract enterozoon like lumbricoid and whipworm are most likely to occur among family members. Conclusion]The infection rate of intestinal tract enterozoon has been decreasing significantly in the last 10 years, which indicates the great progress in expelling parasites in this area. The infection rate of whipworms is significantly higher than that of lumbricoid because the anthelmintic is mainly used to deal with lumbricoid. Great emphasis should be put on the health education among rural residents. Regular actions should be carried out to control the prevalence of intestinal tract enterozoon.
