Diversity of ticks (Acari: Ixodidae) infesting cheetahs (Acinoyx jubatus) at three breeding centres in South Africa and activity patterns of questing ticks.

Ticks were collected from 191 cheetahs at three breeding centres in North West and Limpopo Provinces, South Africa. Haemaphysalis elliptica, a common tick of large felids, was the most abundant species collected, while Amblyomma hebraeum and Rhipicephalus simus occurred in lower numbers. In addition to these three species, drag-sampling of the vegetation revealed the presence of Amblyomma marmoreum, Rhipicephalus (B.

Determination of reference values for intraocular pressure and Schirmer tear test in clinically normal ostriches (Struthio camelus).

The purpose of this study was to establish normal physiologic reference values for intraocular pressure (IOP) and Schirmer tear test (STT) results in clinically normal ostriches (Struthio camelus). Twenty ostriches of both sexes, 10 juveniles (1.5-2 yr of age) and 10 adults, were included in this study.

Intraocular pressure and Schirmer tear test results in clinically normal Long-Eared Hedgehogs (Hemiechinus auritus): reference values.

Objective: The present study was undertaken to establish reference values for Schirmer tear test (STT) and intraocular pressure (IOP) in the long-eared hedgehog (Hemiechinus auritus).

Animals: Fourteen healthy long-eared hedgehogs (H. auritus) of either sex were studied.
