Infection with Sarcocystis is common in many species of wild cervids but none is reported from the black-tailed deer (Odocoileus hemionus columbianus). Here, we report Sarcocystis infection in two black-tailed deer from northwest USA for the first time. Sarcocysts were microscopic, up to 556 μm long and mature. The sarcocyst wall was up to 1.39 μm thick and had rectangular 1.17-μm-long villar protrusions, type 17, with thin (230 nm) electron dense ground substance layer. Molecular characterization and phylogenetic analysis indicated that Sarcocystis in the black-tailed deer is related to structurally distinct Sarcocystis species in cervids. A new name, Sarcocystis mehlhorni, is proposed for the Sarcocystis species in black-tailed deer.
在许多野生鹿类物种中，感染肉孢子虫很常见，但黑尾鹿（Odocoileus hemionus columbianus）尚未有相关报道。在此，我们首次报告了来自美国西北部的两只黑尾鹿感染肉孢子虫的情况。肉孢子虫肉眼不可见，最长可达556微米且已成熟。肉孢子虫囊壁最厚达1.39微米，具有1.17微米长的矩形绒毛状突起，属于17型，其电子致密基质层较薄（230纳米）。分子特征分析和系统发育分析表明，黑尾鹿体内的肉孢子虫与鹿类中结构不同的肉孢子虫物种有关。我们为黑尾鹿体内的肉孢子虫物种提出了一个新名称——梅氏肉孢子虫（Sarcocystis mehlhorni）。
