Eimeria galago Poelma, 1966.
Type host: Galago senegalensis É. Geoffroy,
1796, Northern lesser bush-baby.
Other hosts: None reported to date.
Type locality: AFRICA (?).
Geographic distribution: AFRICA (?); EUROPE: The
Netherlands, Amsterdam, Amsterdam Zoo.
Description of oocyst: Oocyst shape: subspheroid;
number of walls: 1; wall
thickness: 1; wall characteristics: smooth, colorless; L x W: 22.1 x 20.6 (20-25 x
19-23); L/W ratio: 1.1; M: absent; OR: present; OR characteristics: composed of
granules; PG: absent. Distinctive features of oocyst: thin, smooth, 1-layered outer
Description of sporocysts and sporozoites:
Sporocyst shape: ovoid or lemon-shaped,
with thin, smooth wall ~0.5; L x W: 10.2 x 8.0 (9-12 x 6-9); L/W ratio: 1.3; SB:
present; SB characteristics: button-shaped; SSB: absent; PSB: absent; SR: present;
SR characteristics: finely granular; SP: arranged randomly within sporocyst, without
RB. Distinctive features of sporocyst: random arrangement of SP in sporocyst, as
they usually are arranged longitudinally.
Prevalence: Oocysts were recovered from 1/3 (33%)
G. senegalensis that died at the Amsterdam Zoo on the day after its arrival.
Sporulation: Exogenous. Oocysts sporulated within
12 days in 4% aqueous potassium dichromate solution at 20-24ºC.
Prepatent and patent periods: Unknown.
Site of infection: Unknown. Oocysts recovered from
intestinal contents and feces.
Material deposited: None.
Remarks: The type host was imported into the
Amsterdam Zoo from Africa. Poelma (1966) noted that the mucous membrane of the
jejunum had Amuch mucous and blood with
some oocysts. Unfortunately, oocysts of 3 Eimeria spp. and Isospora
Rodhain, 1933 (see below) also were described from this animal, so it is impossible
to know conclusively to which parasite species to attribute these jejunal oocysts.
This species has not been reported since its original description.
Reference: Poelma (1966).
