However, coccidiosis or eimeriosis is a disease that causes a health problem of growing economic importance in Brazilian cattle. The aim of this study was to identify the species of Eimeria present in the faeces of buffalo, their distribution, frequency and prevalence in the State of Rio de Janeiro, as well as in the regions studied. Regarding morphotypes found observed the presence of three specific species such as buffalo E. bareillyi, E. ankarensis and E. gokaki, and the latter two species were noted for the first time in Brazil. And the morphotypes common to cattle and buffalo, buffalo were found in E. alabamensis, E. auburnensis, E. bovis, E. brasiliensis, E. cylindrica, E. ellipsoidalis, E. subspherica and E. zuernii. The most prevalent species in the state of Rio de Janeiro was E. zuernii, but this is not observed when analyzing the frequencies of each species per meso studied, and E. auburnensis more prevalent in the regions North Fluminense, Metropolitan and Northwest Fluminense, E. ellipsoidalis more prevalent in Central Fluminense and Coastal Lowlands, E. zuernii mesoregion in South Fluminense. The distribution of the genus Eimeria was not homogeneous, even within a meso, having been observed buffalo with a single species or with up to eight species of the genus Eimeria, these results may characterize properties of extensive creations where the animals have remained independent of age and sex persist for a long time. The morphometric characteristics observed in both the oocysts and sporocysts we were better detailed in this study. / A bubalinocultura ? considerada como uma grande op??o para pecu?ria nacional. No entanto, a coccidiose ou eimeriose ? uma enfermidade que gera um problema sanit?rio de import?ncia econ?mica crescente na pecu?ria brasileira. O objetivo deste estudo foi identificar as esp?cies de Eimeria presentes nas fezes de b?falos, sua distribui??o, frequ?ncia e preval?ncia no estado do Rio de Janeiro, assim como, nas mesorregi?es estudadas. Quanto aos morfotipos encontrados observou-se a presen?a de tr?s esp?cies espec?ficas de b?falos como E. bareillyi, E. ankarensis e E. gokaki, sendo que as duas ?ltimas esp?cies foram assinaladas pela primeira vez no Brasil. E os morfotipos comuns a bovinos e b?falos, encontrados em b?falos foram: E. alabamensis, E. auburnensis, E. bovis, E. brasiliensis, E. cylindrica, E. ellipsoidalis, E. subspherica e E. zuernii. A esp?cie mais prevalente no estado do Rio de Janeiro foi E. zuernii, por?m isto n?o se observa quando analisadas as frequ?ncias das esp?cies por cada uma das mesorregi?es estudadas, sendo E. auburnensis mais prevalente nas mesorregi?es Norte Fluminense, Metropolitana e Noroeste Fluminense, E. ellipsoidalis mais prevalente no Centro Fluminense e Baixada Litor?nea, E. zuernii na mesorregi?o do Sul Fluminense. A distribui??o das esp?cies do g?nero Eimeria n?o foi homog?nea, mesmo dentro de uma mesorregi?o, tendo sido observado b?falos com uma s? esp?cie ou com at? oito esp?cies do g?nero Eimeria; esses resultados podem caracterizar propriedades de cria??es extensivas onde a perman?ncia dos animais, independente da idade e sexo persistem por um longo tempo. As caracter?sticas morfom?tricas observadas, tanto nos oocistos como nos esporocistos, foram mais bem detalhadas neste estudo.
