Аннотация
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.
