Eimeria perardii Yakimoff and
Type host: Erinaceus europaeus
Linnaeus, 1758, Eurasian hedgehog.
Type locality: EUROPE: Russia,
Polotzk District, Leningrad Zoo.
Geographic distribution: EUROPE: Russia;
Description of oocyst: Oocyst shape:
ovoid; number of walls: 1;
wall thickness: unknown, but probably <1;
wall characteristics: outer layer yellowish, apparently smooth;
L x W: 20 x 14.9 (17-27 x 15-16);
L/W ratio: 1.3;
Distinctive features of oocyst: ovoid shape with PG.
Description of sporocysts and
Sporocyst shape: ovoid to ellipsoid (?);
L x W: unknown, but the drawing suggests them to be about 1/2 the length
of the oocyst;
SP: without a distinct RB, although this was not stated in the orginal
Distinctive features of sporocyst: lack of a SB< SR and RB.
Prevalence: 1 of 34 (3%).
Prepatent and patent periods:
Site of infection: Unknown. Oocysts
recovered from feces.
Materials deposited: None.
Remarks: The description of this species
is only marginally useful; it is retained as valid only because oocyst
measurements and an original line drawing were included. Glebezdin and
Kolodenko (1969) said they found this species in hedgehogs in Turkmenia,
but the oocysts they measured were 22.6 x 19.8 (17-26 x 14.5-24.5) and
sporocysts were 10.1 x 7.0 (9-12 x 6-10) and they did not provide a line
drawing or photomicrograph. Thus, the oocysts they measured, likely, were
of a different species than E. perardii. Golemansky (1979) also reported
finding this species in 1/3 E. europaeus from the Sreburna Reserve in
Bulgaria; the oocysts he measured were 24 x 18. Finally, Glebezdin (1985)
again reported finding E. perardii in hedgehogs (H. auritus ?) from
southeastern Turkmenestan but, this seems unlikely.
