河南省豫东平原片区人群肠道寄生虫调查报告

本文报告河南省豫东平原１０个县（市）人群的肠道寄生虫感染情况。按全国人体寄生虫分布调查实施细则的要求和方法，共检查２２４２４人，查见寄生虫感染者１５５２７例，其感染率为６９．２％。查见寄生虫２０种，其中线虫７种，绦虫３种，吸虫１种和原虫９种。各种寄生虫感染率分别为：蛔虫４５．４％、鞭虫４．６％、蛲虫０．０６％（粪检结果，１５岁以下儿童肛拭结果２５．３％）、钩虫２７％（幼虫培养结果为十二指肠钩虫１９．６％，美洲钩虫１．３％）、华支睾吸虫０．３％、带绦虫０．０１％、缩小膜壳绦虫０．０４％、微小膜壳绦虫０．０２％、东方毛圆线虫０．０１％、粪类圆线虫０．０１％、溶组织内阿米巴０．６％、结肠内阿米巴３．８％、哈氏内阿米巴３．９％、贾第虫７．２％、迈氏唇鞭毛虫０．１％、肠内滴虫０．０３％和人芽囊原虫１．１％。     

青海省牧业区人体寄生虫分布及分析

按全国人体寄生虫分布调查实施细则的要求，于１９８９－１９９１年间对青海省牧业区１０个调查点的４８３８人进行了调查，结果其寄生虫总感染率为３２．１％，共查见人体寄生虫１３种，其中蠕虫５种，原虫８种。各种寄生虫的感染率分别为：蛔虫１２．８％、鞭虫０．７％、溶组织内阿米巴０．５％、结肠内阿米巴７．６％、哈氏内阿米巴０．３％、微小内蜒阿米巴４．６％、布氏嗜碘阿米巴０．７％、贾第虫７．１％、结肠小袋纤毛虫０．０２％、人芽囊原虫２．２％、牛带绦虫１．２％；１２岁以下儿童蛲虫感染率为１５．５％（２１６／１３９７）；包虫病平均患病率为３．０％。蛔虫感染者中９９．８％为轻、中度感染者。多虫感染占１８．２％。结果提示，青海省牧业区蛔虫、蛲虫分布较广，感染水平亦属本区最高，尤以集体生活的少年儿童感染为重。但同我国其它部分地区相比，尚属低感染程度，这同高原大陆性气候相关密切。而流行分布最广、危害最重的乃属绦虫类疾病中的包虫病，这是我省寄生虫病防治工作的重点。

Intestinal parasitic infections in schoolchildren of Abha (Asir), Saudi Arabia.

Stool specimens from 1282 children between the age of 5 and 13 years attending 10 primary schools for boys in the city of Abha, southwestern Saudi Arabia, were examined for the presence of intestinal parasites. Of these, 313, (24.4%) were found infected with one or more species of 11 intestinal protozoa and helminths. The most common pathogenic protozoa being Giardia lamblia (10.9%) followed by Entamoeba histolytica (4.1%). The nonpathogenic protozoan, Entamoeba coli had the highest prevalence rate (11.3%) in the children's stools. Hymenolepis nana was the commonest intestinal helminth (3.0%). Other intestinal helminths, including Ascaris lumbricoides, Trichuris trichiura. Schistosoma mansoni, Dicrocoelium dendriticum were detected to a lesser extent. The distribution of the common intestinal infections among the children surveyed were also analysed according to age, nationality and multiplicity of infection. Prevalence of E. histolytica was found to increase with age whereas Giardia infections were less common among older children. This pair of parasite species were strongly associated. Yemeni children had consistently the highest prevalence of infection with protozoa and helminths, followed by Saudi and non-Saudi children.     

A survey of gastrointestinal parasites in Ogun State, southwest Nigeria

To study the epidemiology of intestinal parasites in Ogun State, Nigeria, 479 stool specimens were examined at a hospital in Abeokuta during the rainy season in June 1986. Intestinal helminths and/or protozoa were present in 297 samples (62%). 41.1% of the specimens showed a single infection, 34% showed double, 20% triple and 5% quadruple infection. The most commonly found worm was Ascaris lumbricoides (in 40% of specimens), followed by Trichuris trichiura (23.2%), hookworms (19.2%), Strongyloides stercoralis (2.1%) and Dicrocoelium sp. (0.4%). Pathogenic protozoa found were Entamoeba histolytica (7%), Giardia intestinalis (4.2%), Blastocystis hominis (2.5%) and Cryptosporidum sp. (2.3%). The apathogenic protozoa Entamoeba coli, Chilomastix mesnili, Trichomonas hominis and Iodamoeba buetschlii were also seen.

Prevalence of intestinal parasite infections among patients in local public hospitals of Hail,Northwestern Saudi Arabia

Objective:To evaluate the prevalence of intestinal parasites among patients in Hail,Northwestern Saudi Arabia.Methods:Stool samples were collected from 130 patients(69females and 61 males) in Hail General Hospital.Each sample was examined by direct wet mount microscopic examination using both normal saline and Lugol's iodine preparation and concentration techniques using salt and formol-ether solutions.Permanent stained smears were performed for intestinal coccidian using modified Ziehl-Neelsen technique.Results:The overall prevalence of intestinal parasitic infection was 45.38%(59 cases).Forty-four(33.84%)were found to be infected with one or more intestinal protozoa.5(3.84%) were infected with helminthes and 10(7.69%) had mixed infection with both helminthes and protozoa.The most common intestinal helminth detected was Ancyloxtoma duvdenale(n=5.3.84%),followed by Ascaris lumlmcnidex.Taenia sp.and Trichuris trichiura(n=2 for each species,1.5%).For intestinal protozoa,the coccidian Cryptosporidium parvum(n=25,19.23%) was the most common followed by Entamoeba histolytica/dispur(n=21,16.15%),Giurdia lamblia(n=15,11.54%),Entamoeba coli(n=5.3.85%) and Blastocysts hominis(n=3,2.30%).The prevalence of intestinal parasitic infections in females was significantly higher than in males(P0.05).Conclusions:This is the first study highlighting that intestinal parasites are still an important public health problem in Northwestern Saudi Arabia Therefore,health education would be the best way to prevent from intestinal parasite infections which are mainly food borne diseases.

Intestinal parasitic infections in HIV/AIDS and HIV seronegative individuals in a teaching hospital, Ethiopia

The magnitude of intestinal parasitic infection in human immunodeficiency virus (HIV) /AIDS patients requires careful consideration in the developing world. However, there have been very few studies addressing this issue in Ethiopia. This study was conducted to determine the prevalence of intestinal parasitic infection in HIV/AIDS patients at Jimma Hospital, Southwest Ethiopia, between January and February 2002. Stool specimens from HIV/AIDS patients and control groups were screened for intestinal parasitic infections using direct and formalin-ether sedimentation concentration methods. Out of 78 HIV/AIDS patients, 52.6% (41/78), and out of 26 HIV-negative individuals, 42.3% (11/26), were infected with one or more types of intestinal protozoa and/or helminthes. The parasites detected among HIV/AIDS patients included Ascaris lumbricoides (30.8%), Blastocystis spp. (14.1%), Entamoeba histolytica (10.3%), Trichuris trichiura (6.4%), Strongyloides stercoralis (5.1%), Giardia lamblia (3.8%), Schistosoma mansoni (2.5%), hookworm species (2.5%), and Taenia spp. (1.3%). Multiple infections were more common among HIV/AIDS patients. Blastocystis spp. were found to be significantly higher in HIV/AIDS patients than in controls (P < 0.05). The magnitude of intestinal parasitic infection was high both in HIV/AIDS patients and in controls. Routine examinations of stool samples for parasites would significantly benefit the HIV-infected and uninfected individuals by contributing to reduce morbidity.
