摘要
在江苏省城乡7个居民点进行人体感染隐孢子虫情况的调查,各点均查见隐孢子虫感染者,人群隐孢子虫感染率为0.7％-3.8％,平均为 1.6％(97/6 221);其中儿童的为 1.8％(89/5 089),成人的为0.7％(8/1 132)。在门诊病人中隐孢子虫检出率为3.3％(39/1 172),其中儿童的为 3.6％(38/1 056),成人的为0.9％(1/116),病例来自徐州市及毗邻的江苏、安徽两省的8县。136 例隐孢子虫感染者中,婴幼儿为 65.4％(89/136),是本病的多发人群组。腹泻为本病的主要临床表现,本组有 69.1％(94/136)出现腹泻,呈水样便或粘液稀便。本文对患儿隐孢子虫感染与免疫,本病的流行因素进行了初步探讨。
A survey of cryptosporidiosis in outpatients and inhabitants in Xuzhou city and 6 rural areas of Jiangsu Province was carried out from 1989 to 1991.Cryptosporidium oocysts(CSO) were found in 97((1. 6%)of 6 221 individuals as a whole, and were detected in 39 (3. 3%) of 1 172 outpatients among the examinees. 39 cases were from 31 towns and villages of 8 counties near Xuzhou city. Among the 136 cases,83 were males and 53 females,of them 89 (65. 4%)were infants and young children. The incidence was evidently higher in the group of children under 4 than in that aged 4 to 15(P<0. 01). Diarrhea,intermittent or persistent,was the main symptom of cryptosporidiosis,being present in 94(69. l%)of the 136 positive cases, while the other 42 were asymptomatic carriers. The results of routine blood examination and immunoassay performed in a part of the infected children indicated that more than half of them had anemia and lessened cellular immunity. Stool examination of the domestic animals of the affected households showed that a pig and a dog were CSO positive.
