Cryptosporidia organisms were detected histologically in the microvillus brush border of 5.3% (184/3,491) of consecutive live pigs submitted for routine diagnostic evaluation between 1981 and 1985. Infected pigs came from 133 farms and usually were 6 to 12 weeks old, but ranged from 1 to 30 weeks old. Organisms were found in the jejunum, ileum, cecum, and colon, but primarily in microvilli of dome epithelium in the ileum. A seasonal incidence was not observed. Only 26% of the cryptosporidia-infected pigs had diarrhea, and most of those had other primary diarrheagenic agents or lesions capable of causing their diarrhea.
在1981年至1985年间提交进行常规诊断评估的连续活猪中，经组织学检测发现，5.3%（184/3491）的猪在微绒毛刷状缘存在隐孢子虫。受感染的猪来自133个农场，通常为6至12周龄，但年龄范围为1至30周龄。在空肠、回肠、盲肠和结肠中发现了隐孢子虫，但主要存在于回肠穹窿上皮的微绒毛中。未观察到季节性发病情况。仅26%的隐孢子虫感染猪出现腹泻，且其中大多数还有其他原发性致泻因子或能够导致腹泻的病变。
