Abstract

Between October 1, 1983 and October 31, 1984, fecal specimens from 3656 persons with enteritis and 182 calves, representing 148 herds having a neonatal diarrhea problem, were examined for oocysts of Cryptosporidium spp. Oocysts were found in 1% of human and 25% of bovine specimens. All infected persons were immunocompetent. Children under five years of age had an infection rate of 25/100,000 compared to 1.4/100,000 in older people (p less than 0.005). Rates in northern communities were four to seven times as high as those in southern Manitoba. Human infections occurred most commonly in late summer and fall. In beef calves infection occurred in winter and spring, the calving season in Manitoba. Epidemiological association between the infection in people and in cattle could not be established.

摘要

在1983年10月1日至1984年10月31日期间,对3656名肠炎患者以及182头犊牛(代表148个存在新生犊牛腹泻问题的牛群)的粪便样本进行了隐孢子虫属卵囊检测。在1%的人类样本和25%的牛类样本中发现了卵囊。所有受感染的人均具有免疫能力。五岁以下儿童的感染率为25/100,000,而老年人的感染率为1.4/100,000(p小于0.005)。北部社区的感染率是曼尼托巴省南部的四至七倍。人类感染最常发生在夏末和秋季。肉牛犊的感染发生在冬季和春季,即曼尼托巴省的产犊季节。无法确定人与牛感染之间的流行病学关联。
