New Cyclospora species from Ethiopian monkeys

Characteristics Cyclospora cercopitheci C. colobi C. papionis
Host Cercopithecus aethiops Linnaeus, 1758, African green or vervet monkey Colobus guereza Ruppell, 1835, colobus monkey Papio anubis Lesson, 1827, olive baboon
Oocysts Spherical; 8 - 10 µm (mean 9.2) in diameter. Outer wall smooth. Wall autofluoresces in UV wavelength. Small, spherical, 8 - 9 µm (mean 8.3) in diameter. Outer wall smooth. Wall autofluoresces in UV wavelength. Spherical, 8 - 10 µm (mean 8.8) in diameter. Outer wall smooth. Wall autofluoresces in UV wavelength.
Sporocysts Two per mature oocyst Lemon-shaped, 6-7 by 4-5 µm, with L/W ratio 1.5 Two per mature oocyst Lemon-shaped, 7-8 by 4-5 µm, with L/W ratio 1.66 Two per mature oocyst Lemon-shaped, 7-8 by 4-5 µm, with L/W ratio ratio 1.66
Stieda bodies A prominent stieda body present; sub- and parastieda bodies absent A prominent stieda body present; sub- and parastieda bodies absent A prominent stieda body present; sub- and parastieda bodies absent
Sporocyst residuum Prominent; made up of clumped globules Prominent, irregularly shaped; 2-4 µm in diameter Prominent, irregularly shaped; 2-3 by 3-4 µm in diameter
Micropyle Absent Absent Absent
Sporozoites Two per sporocyst 10-13 by 1.5 µm; tapered at both ends Two per sporocyst 10-13 by 2 µm; tapered at both ends Two per sporocyst 10-13 by 1.5 µm; tapered at both ends
Remarks Marginally larger than other two species Heterozygotic position, T or A at position #280; therefore, SSU-rRNA sequences submitted separately. Assigned accession nos. AF111184 and AF111185 Marginally smaller than the two other species Sequence of SSU-rRNA assigned accession no. AF111186. Poorest sporulation rate of three species The most commonly encountered of the three species. Sequence of SSU-rRNA assigned accession no. AF111187
