Abstract：
:Ruminant coccidiosis is a gastrointestinal disease caused by parasites of the genus Eimeria. Environmental and climatic factors are relevant for the development, survival, and transmission of coccidiosis because Eimeria oocysts are able to survive in the environment for several weeks or months in favorable conditions of moderate heat and moisture. The aim of the present study was to georeference, for the first time, the locations of Eimeria occurrences in Mexico from 1961 to 2018. A dataset was created for 3414 reports of Eimeria occurrences in cattle, sheep, and goats in Mexico. Twelve species of Eimeria that infect cattle were recorded, 11 Eimeria species of sheep are present in Mexico, and eight species of goats are geographically distributed in the country. In the current findings, it has been observed that Eimeria colonizes mainly the temperate semihumid, temperate humid, warm humid, and warm semihumid areas during spring and summer in animals younger than 1 year of age. Macroenvironmental variables like temperature and rainfall influence the prevalence of Eimeria in cattle, sheep, and goats, and for some species, the rearing system, facility type, farm size, and altitude affect the occurrence of this parasite. Results may support future studies aimed at reducing the disease prevalence of the parasite in endemic regions of Mexico. The use of recorded cases and climate variables yields a more comprehensive perspective of the epidemiology of eimeriosis, which would be difficult to infer from laboratory studies alone.
