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.
Nous avons examiné 674 échantillons de matières fécales fraîches de cerf porte-musc (Moschus berezovskii Flerov) dans les provinces du Sichuan et du Shaanxi, en Chine, pour les oocystes de coccidies et 65 % étaient infectés par Eimeria spp. Auparavant, seules quatre espèces d’Eimeria étaient connues chez Moschus spp. Nous décrivons ici six nouvelles espèces d’Eimeria. Eimeria aquae n. sp., chez 38 % des cerfs, a des oocystes ovoïdes, 32,0 × 23,0 μm, micropyle (M) et granules polaires (PG) de différentes tailles présents, parfois des résidus d’oocystes (OR) présents; sporocystes ovoïdes, 14,1 × 7,5 μm, avec corps de Stieda (SB) et résidu de sporocyste (SR). Eimeria dolichocystis n. sp., chez 11 % des cerfs; oocystes cylindroïdes, 36,6 × 18,9, avec un M, 1 PG et OR; sporocystes ovoïdes, 13,9 × 7,7, avec SB et SR. Eimeria fengxianensis n. sp., chez 7 % des cerfs; oocystes ovoïdes, 36,3 × 25,2, M et PG présents mais OR absent; sporocystes ovoïdes, 13,9 × 7,3, avec SB et SR. Eimeria helini n. sp. chez 24 % des cerfs; oocystes subsphéroïdaux, 27,0 × 24,1, OR et PG souvent présents, mais M absent; sporocystes ovoïdes, 13,5 × 7,7, avec SB et SR. Eimeria kaii n. sp. chez 26 % des cerfs; oocystes ovoïdes, 33,2 × 20,7, M et PG présents, mais OR absent; sporocystes ovoïdes, 14,4 × 7,5, avec SB et SR. Eimeria oocylindrica n. sp., chez 17 % des cerfs; oocystes cylindroïdes, 36,0 × 21,4, M et 1-2 PG présents mais OR absent; sporocystes ovoïdes, 13,8 × 7,7, avec SB et SR.
