Eimeria condylurae Duszynski, 1989

Type host: Condylura cristata (Linnaeus, 1758), Star-nosed mole.

Other hosts: None reported to date.

Type locality: NORTH AMERICA: USA, Vermont, Lamoille Co., 10.3 km. N of Stowe, off Hwy.100.

Geographic distribution: NORTH AMERICA: USA, Ohio, Vermont.

Description of oocyst: Oocyst shape: subspheroid; number of walls: 2; wall thickness: ~1.5; wall characteristics: outer, smooth, yellow, ~2/3 of total thickness; inner, smooth, pale yellow; L x W: 17.7 x 15.7 (17-23 x 14-21); L/W ratio: 1.1 (1.05-1.25); M: absent; OR: present; OR characteristics: irregularly shaped, highly refractile (transmitted light) body ~2 x 3; PG: absent. Distinctive features of oocyst: thick outer wall and highly refractile OR.

Description of sporocysts and sporozoites: Sporocyst shape: elongate-ellipsoid, pointed at both ends; L x W: 11.7 x 5.6 (11-14 x 5-6); L/W ratio: 2.1 (1.9-2.6); SB: present; SSB: present, ~2 times wider than SB; PSB: absent; SR: present; SR characteristics: large granules that may be a compact mass or diffuse and occupies ~1/2 of space in sporocyst; SP: with a large, posterior RB. Distinctive features of sporocyst: large posterior RB of SP and large, granular SR.

Prevalence: 3/24 (12.5%) including 2/12 (17%) from Vermont and 1/6 (17%) from Ohio, but 0/4 from Massachusetts and 0/2 from Maine.

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. 43334 (NK 3024, male), R.M. Sullivan #479, 13 June 1980. Photosyntypes in the USNPC No. 80625.

Remarks: Sporulated oocysts of this species resemble in size and shape those of E. madagascarensis (see Uilenberg, 1967), but differ by being somewhat larger (18 x 16 vs 16 x 15) and by having sporocysts that have a SSB and are pointed at the end opposite the SB.
