Abstract: | A total of 3204 cattle sera, collected between 1966 and 1974, from all seven provinces and 34 of the 42 districts of Kenya were screened in a neutralisation test for antibody to infectious bovine rhinotracheitis virus (IBRV). Antibody to IBRV was found in some sera from all the districts, with cattle over two years old showing the highest incidence. A small number of goat sera also showed some antibody. From the results obtained it is concluded that IBRV infection is widespread in Kenyan cattle. |
