Cryptosporidium spp. is a protozoan parasite that causes enteric infection in a wide range of hosts, including livestock and humans. The aim of this cross-sectional study was to estimate the prevalence of Cryptosporidium spp. in small ruminants in Grenada, West Indies. Fecal samples were collected from 100 sheep and 202 goats from 32 farms. The fecal samples were tested using an Enzyme-linked immunosorbent assay (ELISA) for qualitative detection of antigens in feces (Diagnostic Automation Inc., USA). The overall prevalence of Cryptosporidium spp. was 19.5% [95% confidence interval (CI): 15.4% to 24.4%] in both sheep and goats. The prevalence of Cryptosporidium spp. in sheep and goats was 14% (95% CI: 8.4% to 22.3%) and 22.3% (95% CI: 17.1% to 28.5%), respectively. There was no significant difference in the prevalence of Cryptosporidium spp. infection between sheep and goats (p = .42, Fisher's exact test) in Grenada. Of the 32 farms visited, 19 (59.4%) had at least one Cryptosporidium spp. positive animal.
隐孢子虫属是一种原生动物寄生虫，可在包括家畜和人类在内的多种宿主中引起肠道感染。这项横断面研究的目的是估计西印度群岛格林纳达小反刍动物中隐孢子虫属的流行率。从32个农场的100只绵羊和202只山羊中采集粪便样本。使用酶联免疫吸附测定（ELISA）对粪便样本进行检测，以定性检测粪便中的抗原（美国诊断自动化公司）。绵羊和山羊中隐孢子虫属的总体流行率为19.5%[95%置信区间（CI）：15.4%至24.4%]。绵羊和山羊中隐孢子虫属的流行率分别为14%（95%CI：8.4%至22.3%）和22.3%（95%CI：17.1%至28.5%）。在格林纳达，绵羊和山羊之间隐孢子虫属感染的流行率没有显著差异（p = 0.42，Fisher精确检验）。在所走访的32个农场中，19个（59.4%）至少有一只隐孢子虫属阳性动物。
