Abstract

Coprological examination of 15 Indian peacocks, Pavo cristatus check for this species in other resources , revealed the presence of a coccidium species of the genus Eimeria, which apparently represents a previously undescribed species. Sporulation is exogenous and fully developed oocysts of Eimeria pavoaegyptica check for this species in other resources sp. nov. are ellipsoidal, with a dimension of 15 (13-16) × 12 (10- 12.9) µm and with a shape index of 1.25 (1-1.3). The sporulated oocysts have no micropyle but enclose one large rectangular-shaped polar granule and an oocyst residuum. The oocysts have a distinct two-layered wall, which is ~1.7 µm thick. The outer layer has a smooth texture; it fills ~¾ of the total thickness and appears bicolored. The sporocysts are boat-shaped, of about 10 (9-11) × 4 (4-4.7) µm; their average shape-index is 2.5 µm with a small pointed Stieda body and a smooth, thin single-layered wall. No substieda body is detected. The sporocysts con- tain numerous, nearly uniform granular residua. The sporozoites are banana-shaped, 6 × 3 µm and each has two different-sized refractile bodies.
