A red-necked wallaby (Macropus rufogriseus) in the Republic of Korea, introduced from Australia, died in 12 d after exhibiting anorexia and diarrhea. Postmortem examination revealed that the wallaby died due to coccidiosis by Eimeria sp. Morphologically, Eimeria sp. identified closely resembled E. mykytowyczi. The 18S rRNA sequence analysis showed that Eimeria sp. identified in this study has a 98.5% identity with that in Australian red kangaroo (M. rufus). However, owing to insufficient molecular information on marsupial-specific Eimeria, exact species could not be determined. Phylogenetically, Eimeria sp. identified in this study belonged to clade five of the marsupial group.
一只从澳大利亚引进至韩国的赤颈袋鼠（Macropus rufogriseus），在出现厌食和腹泻症状12天后死亡。尸检显示，这只袋鼠死于艾美耳球虫（Eimeria sp.）引起的球虫病。从形态学上看，鉴定出的艾美耳球虫与米氏艾美耳球虫（E. mykytowyczi）极为相似。18S rRNA序列分析表明，本研究中鉴定出的艾美耳球虫与澳大利亚红袋鼠（M. rufus）体内的该球虫有98.5%的同源性。然而，由于关于有袋类动物特异性艾美耳球虫的分子信息不足，无法确定其确切种类。在系统发育上，本研究中鉴定出的艾美耳球虫属于有袋类动物组的第五分支。
