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

Bluetongue will be defined as an acute insect borne sickness of ruminants, manifested clinically in sheep through a catarrhal irritation of the mucous mem­ branes of the digestive and respiration platforms and linked to degenerative alterations within the skeletal musculature. The profound emaciation and weak spot which stick with the intense sickness are answerable for a prolonged convalescence and for critical financial losses as a result of decreased productiveness. II. old throughout the early colonisation of Africa, vulnerable Merino and different eu breeds of sheep have been brought into the Cape, at the start 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) files the looks of a significant febrile affliction among those imported sheep within which either morbidity and mortality used to be excessive (cited by way of HENNING, 1949). HuTCHEON (1881) gave this sickness the identify of "Fever" or "Epizootic Catarrh", so that it will distinguish it from different medical stipulations of an identical nature encountered among sheep. within the first com­ prehensive description of this medical syndrome and its epizootiology HuTCHEON (1902) observed it as "Malarial Catarrhal Fever of Sheep", a designation which was once evidently encouraged by means of the fallacious trust that an intracorpuscular parasite was once the first explanation for the disorder. extra systematic experiences have been carried out by way of SPREULL (1902; 1905), who endeavoured to immunize sheep through the simultaneous inoculation of immune serum and infective blood.
