Dourine in Southern Africa 1981-1984: serological findings from the Veterinary Research Institute, Onderstepoort.
The distribution of positive dourine cases found on the complement fixation test at the Veterinary Research Institute, Onderstepoort from 1981 to 1984, is recorded. Within the Republic of South Africa, foci of infection occurred in the Johannesburg, Pretoria, Potchefstroom, Rustenburg, Upington, Lichtenburg, Kroonstad, Louis Trichardt, Middelburg (Cape) and Mossel Bay state veterinary districts. In Bophuthatswana, Transkei, Lesotho, South West Africa and Swaziland, positive cases were also recorded. Anti-complementary activity of horse sera does not present a problem. In donkey and mule sera, however, sera show anticomplementary activity in approximately 50% of cases. This can be reduced by diluting the sera 1/2 before inactivating at 63 degrees C for 1 h.
