Eimeria motleiensis Ford and Duszynski, 1988
Type host: Scalopus aquaticus (Linneaus, 1758), Eastern American mole.
Other hosts: None reported to date.
Type locality: NORH AMERICA: USA, Texas, Motley Co.
Geographic distribution: NORTH AMERICA: USA, Texas.
Description of oocyst:
Oocyst shape: subspheroid;
number of walls: 2;
wall thickness: >1.0;
wall characteristics: outer, mammillated, ~2/3 of total thickness; inner, smooth;
L x W: 17.0 x 15.3 (15-20 x 13-18);
L/W ratio: 1.1 (1.0-1.2);
Distinctive features of oocyst: knobby, mammillated outer wal, absence of PG.
Description of sporocysts and sporozoites:
Sporocyst shape: ovoid;
L x W: 10.7 x 6.8 (10-13 x 6-8);
L/W ratio: 1.6 (1.4-1.75);
SSB: present, same width as SB;
SR characteristics: small granules as compact sphere or band-shaped body between SP;
SP: with 2 prominent RB.
Distinctive features of sporocyst: combination of SB-SSB complex and 2 RB in SP.
Prevalence: 7/13 (54%).
Sporulation: Exogenous. Oocysts sporulated in 7-10 days in 2.5% aqueous (w/v) potassium dichromate solution at 23 C.
Prepatent and patent periods: Unknown.
Site of infection: Unknown. Oocysts recovered from feces and intestinal contents.
Materials deposited: Skin, skull, skeleton and tissues of the symbiotype host are preserved in the Mammal Division of the Museum of SW Biology, UNM: MSB No. 42354 (NK 2048), D.W Moore #719, 20 May, 1980. Photosyntypes in the USNPC No. 85998.
Remarks: Oosysts of this species resemble those of E.bentongi, E. blarinae, and E. madagascarensis. They differ from those of E. bentongi by having an oocyst with a sculptured (vs smooth) outer wall and an OR; they also lack a PG that is present in E. bentongi and have sporocysts with a SB, which the latter lacks. They differ from those of E. blarinae by being somewhat smaller (17 x 15 vs 21 x 18), by lacking a PG, and by having a SB. They differ from those of E. madagascarensis by having a thicker oocyst wall (>1.0 vs 0.5) that is sculptured rather than smooth, by having an OR and sporocysts with a SSB, and by not having a PG. .
