The aim of the present study was to find out the diversity of Eimeria species in cattle herds in the semiarid region of Brazil. Forty cattle fecal samples were collected from 20 farms in the Paraíba State, Northeast Brazil, and examined by centrifugation-floatation technique in sucrose solution. From each positive animal, 20 oocysts were photographed and measured. Infection by Eimeria spp. was detected in 17.12% (137/800) of the samples analyzed. All the farms had at least one animal that was positive for Eimeria spp. (100%; 20/20). In total, 2740 coccidia were photographed and measured. The species detected were: Eimeria bovis (35.1%); Eimeria canadensis (17.48%); Eimeria auburnensis (14.7%); Eimeria ellipsoidalis (9.7%); Eimeria zuernii (7.22%); Eimeria brasiliensis (4.56%); Eimeria bukidnonensis (3.97%); Eimeria illinoisensis (2.91%); Eimeria wyomingensis (1.42%); Eimeria alabamensis (1.27%); Eimeria cylindrica (0.76%); Eimeria pellita (0.54%); Eimeria ildefonsoi (0.21%); and Eimeria subspherica (0.07%). It was concluded that cattle in the semiarid region of Brazil were parasitized by 14 species of Eimeria. It is thinked that the sanitary management employed, as well as the system used for raising these animals, is the crucial point that leads to high rates of infection in this region.
本研究旨在调查巴西半干旱地区牛群中艾美尔球虫的多样性。从巴西东北部帕拉伊巴州的 20 个农场采集了 40 份牛粪便样本，并用蔗糖溶液离心漂浮技术进行检查。从每只阳性动物中拍摄并测量了 20 个卵囊。分析的 800 份样本中，有 17.12%（137/800）检测到艾美尔球虫感染。所有农场至少有一只动物对艾美尔球虫呈阳性（100%；20/20）。总共拍摄和测量了 2740 个卵囊。检测到的物种有：牛艾美尔球虫（35.1%）；加拿大艾美尔球虫（17.48%）；奥本艾美尔球虫（14.7%）；椭圆形艾美尔球虫（9.7%）；祖尔奈艾美尔球虫（7.22%）；巴西艾美尔球虫（4.56%）；布基德农艾美尔球虫（3.97%）；伊利诺伊艾美尔球虫（2.91%）；怀俄明艾美尔球虫（1.42%）；阿拉巴马艾美尔球虫（1.27%）；圆柱艾美尔球虫（0.76%）；小艾美尔球虫（0.54%）；伊尔德丰索艾美尔球虫（0.21%）和类球形艾美尔球虫（0.07%）。结论是，巴西半干旱地区的牛被 14 种艾美尔球虫寄生。认为在该地区，采用的卫生管理以及饲养这些动物的系统是导致高感染率的关键因素。
