广西百色市人体重点寄生虫病调查结果
|
摘要
目的了解百色市人体重点寄生虫病的流行现状和态势。方法按照《广西人体重点寄生虫病现状调查实施细则》的要求,选取百色市2个县的3个调查点开展土源性线虫病(包括钩虫病、蛔虫病、鞭虫病、蛲虫病)、带绦虫病、华支睾吸虫病和肠道原虫病的调查。每个调查点调查不少于250人,共调查800人。采集监测对象粪便标本,采用改良加藤厚涂片(Kato-Katz法),对受检者进行粪检(一粪两检),检查土源性线虫、带绦虫、华支睾吸虫等蠕虫虫卵并计数;土源性线虫调查点加做钩蚴试管滤纸培养法,检查并鉴定粪样中的十二指肠钩虫和美洲钩虫;采用碘液涂片法查肠道原虫包囊或滋养体;透明胶纸肛拭法查蛲虫卵。结果百色市肠道寄生虫感染者130人,总感染率为16.25%,共检出肠道寄生虫7种,包括线虫4种,吸虫1种,原虫2种。其中钩虫、蛔虫、鞭虫、蛲虫、华支睾吸虫、结肠内阿米巴、蓝氏贾第鞭毛虫感染率分别为5.38%、3.13%、6.75%、0.50%、0.25%、0.38%、0.38%。土源性线虫占肠道寄生虫感染人数的93.85%。结论相比百色市第1次、第2次全国人体寄生虫调查和广西少数民族地区寄生虫感染调查的结果,百色市人群寄生虫感染率呈下降趋势。感染人群的分布存在地区间的差异。土源性线虫病是防治的重点,特别是农村地区,少数民族居住地,经济欠发达地区,中小学生和学龄前儿童是以后宣传教育工作的主要对象。
Objective To know the status of human important parasitic diseases in Baise.Methods This survey wascarried out according to the methods of Guangxi Survey Scheme on Major Human Parasitic Diseases. Soil-transmitted helminthinfections( including ascariasis,trichuriasis,hookworm and enterobiasis),taeniasis,clonorchiasis and intestinal protozoiasiswere investigated in 3 surveyed sites from 2 counties( cities or districts) in Baise. A total of 800 people were investigated,withmore than 250 in each site. Fecal specimens were collected. Modified Kato-Katz thick smear method was used for examiningintestinal helminths,test tube filter paper culture method for identifying the species of hookworm,iodine liquid smear methodfor examining trophozoites or cysts of intestinal protozoa,and cellophane tape method for determining eggs of Enterobius vermicularis. Results In Baise, 130 people were infected with intestinal parasites, with a total infection rate of 16.25%, 7kinds of intestinal parasites were found,including nematodes( 4 species), trematodes( 1 species) and protozoa( 2 species).The infestation rates of Hookworm,Ascaris lumbricoides, Trichuris trichiura, Enterobius vermicularis, Conorchis sinensis,Entamoeba coli and Giardia lamblia hominis were 5.38%, 3.13%, 6.75%, 0.50%, 0.25%, 0.38% and 0.38% respectively. Soil-borne nematode infections accounted for 93.85% of the intestinal parasite infections. Conclusions Compared with theresults of the first and second national survey of human parasites in Baise and the survey of parasite infection in Guangximinority areas, the parasite infection rate of Baise population showed a downward trend. There are regional differences in thedistribution of infected people. Soil-borne nematode disease is the focus of prevention and control, especially in rural areas,ethnic minority areas, economically underdeveloped areas, primary and secondary school students and preschool children arethe main target of future publicity and education.
