Eimeria lemuris Poelma, 1966.
Type host: Galago senegalensis É. Geoffroy,
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 to
ellipsoid; number of walls: 2;
wall thickness: outer 3.9-5.6; inner 0.8; wall characteristics: outer, rough, dark
brown, thick, comprising bulk of the wall; inner, smooth, thin, colorless; L x W:
51.3 x 41.3 (44-57 x 38-47); L/W ratio: 1.2; M: absent; OR: present; OR
characteristics: spheroidal mass composed of a cluster of large granules and
globules; OR L x W: ~13 x 13; PG: absent. Distinctive features of oocyst: its large
size and dark, outer wall, which mask the fine details of the sporocysts.
Description of sporocysts and sporozoites:
Sporocyst shape: lemon-shaped; L
17.3 x 11.5 (17-20 x 10.5-14); L/W ratio: 1.5; SB: present; SSB: absent; PSB:
absent; SR: present; SR characteristics: composed of many coarse granules; SP:
elongate, lying lengthwise in sporocyst, without RB. Distinctive features of
sporocyst: smooth, thin wall ~0.7 and SP without RB.
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
20 days in 4% aqueous
dichromate solution at 20-24ºC.
Prepatent and patent periods: Unknown.
Site of infection: Poelma (1966) specifically
stated that endogenous stages
lemuris were closely recognizable...in paraffin sections of the jejunum and
It is not clear how he determined this.
Material deposited: None.
Remarks: This was the same host imported into the
Amsterdam Zoo from Africa; see remarks for E. galago (above).
Reference: Poelma (1966).
