Diagnosis, distribution and prevalence of Stilesia globipunctata (Rivolta 1874) in sheep in the Overberg region of the southern western Cape Province.

Stilesia globipunctata infections were found in sheep from the area east and south of Bredasdorp in the Overberg region of the southern Cape Province. The prevalence of infection on these farms ranged from 5.1 to 65%. In an abattoir survey 4 of the 6 lots of 4 to 5 year old sheep and only 1 of the 9 lots of sheep under the age of 1 year were infected with S. globipunctata. None of the sheep examined in the Overberg region were infected with Stilesia hepatica. A modified sedimentation technique proved to be the most reliable for the coprological diagnosis of S. globipunctata in sheep.
