Host genus Bufo Laurenti 1768

(13 spp.)

Eimeria mazzai Yakimoff and Gousseff 1934 ( Fig. 1)

Synonym: Eimeria transcaucasica Yakimoff and Gousseff 1936a .

Type host: Bufo bufo L. 1758 (Syn. B. vulgaris ), European common toad.

Other hosts: None reported to date.

Type locality: ASIA: Azerbaijan .

Geographic distribution: ASIA: Azerbaijan.

Description of sporulated oocyst: Oocyst shape: spheroidal; number of walls: 2; wall thickness: unknown; L x W: 16–18 x 16–18; L/W ratio: ~1.0; M, OR, PG: absent. Distinctive features of oocyst: none.

Description of sporocyst and sporozoites: Sporocyst shape: elongate ellipsoidal; L x W: 6–8 x 4; SB: not described, but probably present (line drawing); SSB and PSB: absent; SR: present; SR characteristics: small, irregular granular mass between SZ (line drawing); SZ: comma-shaped with 1 RB at rounded end (line drawing). Distinctive features of sporocyst: none.

Prevalence: Unknown.

Sporulation: Unknown.

Prepatent and patent periods: Unknown.

Site of infection: Unknown. Oocysts recovered from feces.

Endogenous stages: Unknown.

Pathology: Unknown.

Material deposited: None.

Remarks: The description of this species is only marginally useful; it is retained as a valid species only because modest mensural data for the oocyst and sporocysts and an original line drawing were given. Yakimoff and Gousseff (1936a) described E. transcaucasica from Bufo bufo ; their description is almost identical to their earlier description of Eimeria mazzai . Thus, E. transcaucasica is considered the same species.

Isospora stomatici Chakravarty and Kar 1944 emend. Levine 1985 ( Fig. 2)

Synonym: Isospora stomaticae Chakravarty and Kar 1944 .

Type host: Bufo stomaticus Lütken 1864 , Marbled toad.

Other hosts: None reported to date.

Type locality: ASIA: India, Calcutta suburbs .

Geographic distribution: ASIA: India, Calcutta.

Description of sporulated oocyst: Oocyst shape: broadly ellipsoidal to slightly ovoidal; number of walls: 2; wall thickness: very thin; L x W: 25.5 x 17.5 (24–26 x 15–20); L/W ratio: 1.5; M, OR, and PG: absent (line drawing). Distinctive features of oocyst: unsporulated oocysts are initially ovoidal or spheroidal, but become broadly ellipsoidal to ovoidal after sporulation; also, the very thin and fragile, 2-layered wall.

Description of sporocyst and sporozoites: Sporocyst shape: ovoidal; L x W: 15.4–17.6 x 11.0; L/W ratio: unknown; SB: absent ( Chakravarty & Kar 1952) or present ( Mandal 1976), SSB and PSB: absent; SR: present; SR characteristics: generally a conspicuous mass of large granules (line drawing), but it is eventually absorbed with development of the SZ: elongate bodies with one end slightly pointed, 13.2 x 3.3 (12.5–15 x 2.5–4.5); L/W ratio: 1.5; an obvious N is centrally located. Distinctive features of sporocyst: SR prominent in freshly sporulated forms, but disappears with time.

Prevalence: Unknown.

Sporulation: Exogenous, 48–60 h ( Mandal 1976).

Prepatent and patent periods: Unknown.

Site of infection: Intestine.

Endogenous development: Mature meronts are spheroidal and contain 8–12 merozoites, ~6.6 x 3.2, each with a central N and an obvious karyosome. Microgamonts are ovoidal, 17.1–19.3 x 8.6–12.8, with commashaped microgametes, ~3.2–4.3 long. Macrogomonts vary from spheroidal to ovoidal with a diameter of ~15; their cytoplasm is granular with a deeply-staining N.

Pathology: None reported.

Materials deposited: None.

Remarks: This species was named and briefly described in an abstract by Chakravarty and Kar (1944), but without a line drawing; thus, initially, it was a species inquirenda. Later, the same authors ( Chakravarty & Kar 1952) provided a more detailed account including information on the endogenous stages and provided a line drawing to document their observations. Mandal (1976) added further descriptive information which was nearly identical to that of the original description in mensural data of the oocyst and sporocysts; the only significant difference was that in his description of the sporocysts there was a knob-like structure at the anterior

end (SB). Levine (1985) emended the spelling of the specific epitaph when he pointed out that the genitive of - us is - i, not - ae.
