The occurrence of Blastocystis sp. in cattle is reported herein for the first time in Spain. Stool samples from 554 bovines ranging from 3 days old to adults collected from 30 cattle farms in Aragón (northeastern Spain) were concentrated by the formalin-ethyl acetate method and examined light microscopically for the presence of gastrointestinal parasites. Vacuolated cells of Blastocystis sp. was detected in fecal specimens from 10 calves (1.8%) aged from 7 weeks to 6 months. Infected calves were detected at 3 of the 30 farms surveyed (10%). Blastocystis sp. cells were rounded or oval, with a diameter ranging from 6.25 to 15 microns. Blastocystis infection in cattle was never correlated with diarrhea, although infection intensities were generally low.
本文首次报道了西班牙牛群中芽囊原虫的出现情况。从西班牙东北部阿拉贡地区30个养牛场采集了554头年龄从3日龄至成年牛的粪便样本，采用福尔马林 - 乙酸乙酯法进行浓缩，并通过光学显微镜检查胃肠道寄生虫的存在情况。在7周龄至6月龄的10头犊牛（1.8%）的粪便样本中检测到了芽囊原虫的空泡化细胞。在所调查的30个农场中的3个农场（10%）检测到了受感染的犊牛。芽囊原虫细胞呈圆形或椭圆形，直径范围为6.25至15微米。尽管感染强度通常较低，但牛群中的芽囊原虫感染与腹泻从未相关联。
