title: New approaches for morphological diagnosis of bovine Eimeria species: a study on a subtropical organic dairy farm in Brazil.
abstract: Bovine eimeriosis or coccidiosis is an intestinal disease caused by Eimeria spp. which is related to gastrointestinal disorders and, in some cases, death. The current work aimed to identify and provide detailed morphological characteristic features of the different Eimeria spp. parasites of crossbred cows of a subtropical organic dairy farm in Brazil, offering tools for the diagnosis of bovine eimeriosis. Eimeria auburnensis, Eimeria bovis, Eimeria bukidnonensis, Eimeria canadensis, Eimeria cylindrica, Eimeria ildefonsoi, and Eimeria zuernii were identified. The application of line regressions and ANOVA provided a means for the identification of these species. Finally, the current work proposes a dichotomous key to assist in the morphologic identification of bovine Eimeria spp. oocysts.
