Small ruminant resistance against gastrointestinal nematodes: a case of Haemonchus contortus.

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 ...
