ResumoEimeriosis is responsible for causing serious problems in poultry, mainly characterized by reduced weight gain and abnormalities of food conversion efficiency, thereby causing great economic losses. The aim of this study was to evaluate the epidemiology of eimeriosis in broiler chickens in the Araguaina region, State of Tocantins, Brazil. Samples from five farm properties were collected and sent to the Hygiene and Public Health Laboratory, School of Veterinary Medicine and Zootechnics, Federal University of Tocantins. From the parasitological analysis, it was shown that all the properties examined were positive for Eimeria species. 63.1% of the sheds were positive, with findings of oocysts of E. maxima, E. acervulina, E. mitis and E. tenella. It was concluded that all properties evaluated were positive for four species of the genus Eimeria, thus demonstrating that the sanitary strategies followed in poultry rearing had flaws that allowed pathogens to spread in poultry pens.
