We examined 674 fresh fecal samples from forest musk deer (Moschus berezovskii Flerov) in Sichuan and Shaanxi Provinces, China, for coccidian oocysts and 65% were infected with Eimeria spp. Previously, only four Eimeria species were known from Moschus spp. Here we describe six new Eimeria species. Eimeria aquae n. sp., in 38% deer, has ovoidal oocysts, 32.0 × 23.0 μm, micropyle (M) and scattered polar granules (PGs) of various sizes are present, sometimes oocyst residuum (OR) is present; ovoidal sporocysts, 14.1 × 7.5 μm, with Stieda body (SB) and sporocyst residuum (SR). Eimeria dolichocystis n. sp., in 11% deer; cylindroidal oocysts, 36.6 × 18.9, with a M, 1 PG and OR; ovoidal sporocysts, 13.9 × 7.7, with SB and SR. Eimeria fengxianensis n. sp., in 7% deer; ovoidal oocysts, 36.3 × 25.2, a M and PGs present but OR absent; ovoidal sporocysts, 13.9 × 7.3, with SB and SR. Eimeria helini n. sp. in 24% deer; subspheroidal oocysts, 27.0 × 24.1, OR and PGs often present, but M absent; ovoidal sporocysts, 13.5 × 7.7, with SB and SR. Eimeria kaii n. sp. in 26% deer; ovoidal oocysts, 33.2 × 20.7, M and PGs present, but OR absent; ovoidal sporocysts, 14.4 × 7.5, with SB and SR. Eimeria oocylindrica n. sp., in 17% deer; cylindroidal oocysts, 36.0 × 21.4, M and 1-2 PGs present but OR absent; ovoidal sporocysts, 13.8 × 7.7, with SB and SR. Eimeria dujiangyanensis n. nom. is proposed to replace E. moschus Sha, Zhang, Cai, Wang & Liu, 1994, a junior homonym of E. moschus Matschoulsky, 1947.
我们在中国四川省和陕西省检查了 674 份新鲜的林麝（Moschus berezovskii Flerov）粪便样本，发现有 65%感染了艾美球虫。此前，仅从麝香属物种中发现了四种艾美球虫。在这里，我们描述了六种新的艾美球虫。水生艾美球虫（Eimeria aquae n. sp.）在 38%的鹿中感染，其卵囊呈卵圆形，大小为 32.0×23.0μm，有微口（M）和大小不一的散在极粒（PGs），有时有卵囊残余物（OR）；孢子囊呈卵圆形，大小为 14.1×7.5μm，有斯泰达体（SB）和孢子囊残余物（SR）。长形艾美球虫（Eimeria dolichocystis n. sp.）在 11%的鹿中感染，卵囊呈圆柱状，大小为 36.6×18.9μm，有 M、1 个 PG 和 OR；孢子囊呈卵圆形，大小为 13.9×7.7μm，有 SB 和 SR。奉节艾美球虫（Eimeria fengxianensis n. sp.）在 7%的鹿中感染，卵囊呈卵圆形，大小为 36.3×25.2μm，有 M 和 PGs，但无 OR；孢子囊呈卵圆形，大小为 13.9×7.3μm，有 SB 和 SR。海伦艾美球虫（Eimeria helini n. sp.）在 24%的鹿中感染，卵囊呈亚球形，大小为 27.0×24.1μm，OR 和 PGs 常出现，但无 M；孢子囊呈卵圆形，大小为 13.5×7.7μm，有 SB 和 SR。凯氏艾美球虫（Eimeria kaii n. sp.）在 26%的鹿中感染，卵囊呈卵圆形，大小为 33.2×20.7μm，有 M 和 PGs，但无 OR；孢子囊呈卵圆形，大小为 14.4×7.5μm，有 SB 和 SR。奥氏艾美球虫（Eimeria oocylindrica n. sp.）在 17%的鹿中感染，卵囊呈圆柱状，大小为 36.0×21.4μm，有 M 和 1-2 个 PGs，但无 OR；孢子囊呈卵圆形，大小为 13.8×7.7μm，有 SB 和 SR。我们提议用艾美球虫（Eimeria dujiangyanensis n. nom.）来替代艾美球虫（Eimeria moschus Sha, Zhang, Cai, Wang & Liu, 1994），因为后者是麝香属物种的同物异名，易产生混淆。
