A novel Eimeria sp. was identified in faeces collected from a King's skink (Egernia kingii) housed at the Kanyana Wildlife Rehabilitation Centre in Western Australia. Oocysts measure 17.0×15.0 μm with a length/width ratio (L/W) of 1.13. Phylogenetic analysis of 18S rRNA sequences indicated that the novel Eimeria sp. shared the highest genetic similarity to Eimeria antrozoi and Eimeria rioarribaensis from vespertilionid bats from North America (≥98.9%). At the COI locus, bat-derived sequences were not available and phylogenetic analysis placed the novel Eimeria sp. in a clade by itself and shared 98.8% similarity with the rodent-derived species E. falciformis and E. vermiformis. This suggests that the isolate from the King's skink's faeces was probably derived from a mammal, possibly a rodent or a bat.
一种新型的艾美耳球虫（Eimeria sp.）在西澳大利亚州的 Kanyana 野生动物康复中心收容的国王石龙子（Egernia kingii）的粪便中被发现。卵囊大小为 17.0×15.0μm，长宽比（L/W）为 1.13。18S rRNA 序列的系统发育分析表明，这种新型的艾美耳球虫与北美的蝙蝠（蝙蝠科）的艾美耳安特罗佐虫（Eimeria antrozoi）和艾美耳里奥阿利巴虫（Eimeria rioarribaensis）具有最高的遗传相似性（≥98.9%）。在 COI 基因座上，没有蝙蝠来源的序列可用，系统发育分析将新型艾美耳球虫置于一个单独的分支中，与来源于啮齿动物的种艾美耳镰形艾美耳球虫（E. falciformis）和艾美耳线形艾美耳球虫（E. vermiformis）具有 98.8%的相似性。这表明来自国王石龙子粪便的分离株可能来自哺乳动物，可能是啮齿动物或蝙蝠。
