By William R. Hess, Peter G. Howell, Daniel W. Verwoerd

Bluetongue could be defined as an acute insect borne illness of ruminants, manifested clinically in sheep by means of a catarrhal irritation of the mucous mem­ branes of the digestive and respiration structures and linked to degenerative adjustments within the skeletal musculature. The profound emaciation and weak point which stick to the extreme illness are accountable for a chronic convalescence and for severe financial losses because of decreased productiveness. II. historic in the course of the early colonisation of Africa, vulnerable Merino and different eu breeds of sheep have been brought into the Cape, at the beginning via the Dutch East India corporation among 1652 and 1785 and back later in 1870. A record of the livestock and Sheep illnesses fee (1876) documents the looks of a major febrile sickness among those imported sheep during which either morbidity and mortality was once excessive (cited via HENNING, 1949). HuTCHEON (1881) gave this affliction the identify of "Fever" or "Epizootic Catarrh", on the way to distinguish it from different medical stipulations of an analogous nature encountered among sheep. within the first com­ prehensive description of this medical syndrome and its epizootiology HuTCHEON (1902) mentioned it as "Malarial Catarrhal Fever of Sheep", a designation which used to be evidently motivated by way of the incorrect trust that an intracorpuscular parasite used to be the first reason for the disorder. extra systematic experiences have been performed via SPREULL (1902; 1905), who endeavoured to immunize sheep by way of the simultaneous inoculation of immune serum and infective blood.
