Interpretive Summary: Livestock, wildlife, and people experience gastrointestinal diseases caused by infections with species in the genus Eimeria and their relatives. Major losses to agricultural productivity, especially but not exclusively in poultry, result. Human health is compromised when agricultural produce is contaminated with species, such as Cyclospora cayetanensis, that cause human disease. Here, USDA scientists review what is known about the diversity and evolutionary history of this diverse group of organisms, summarizing recent contributions to the field made by comparing genetic characteristics of the myriad parasites, and underscoring the latent potential of new scientific tools to further clarify and diagnose these organisms. The information will of interest to veterinarians, livestock producers, food safety authorities, consumers, and microbiologists.
Technical Abstract: Hundreds of Eimeria species have been described. Our purpose here is to review what is known regarding their diversity and the extent, timing, and drivers of their speciation, referring to the best available estimates of their phylogenetic history.
