Abstract:
Two Eimeria species were identified in faeces collected from a white peacock
(Pavo cristatus) housed at the El-Gharbia city park in Egypt, and each is described as a new
species. Sporulated oocysts of one species (Eimeria pavota) are ellipsoidal, measuring
23.9 x 16.5 (19.5–25 x 14.5–20) µm. The oocysts have a smooth wall made up of two layers
and approximately 1.0 µm in thickness. An oocyst residuum, micropyle and polar granule are
present. Sporocysts have a rounded end opposite knob-like Stieda body and are 14.3 x 7.3
(12–16.5 x 5.5–8) µm in size. The sporozoites contain one refractile body and a diffuse
granular residuum; the entire content of each sporocyst is enclosed by a thin membrane.
Sporulated oocysts of the second eimerian (Eimeria egyptica) are subspherical, measuring
14 x 20 (12–17 x 18–22) µm. The oocysts are without a micropyle but with a two-layered wall,
which is approximately 1.3 µm thick, with the outer layer having a smooth surface texture.
The oocyst residuum and polar granule are present. Sporocysts have a rounded end opposite
the nipple-like Stieda body atop a prominent sub-Stieda body and are 14.4 x 8.0 (12–15.5 x
6.5–9) µm. Sporocysts contain a diffuse granular residuum, and each sporozoite has two
different-sized refractile bodies.
