| Abstract: | Lambs were inoculated with Ehrlichia phagocytophila infected blood at the age of either two or six weeks. The temperature response and degree of parasitaemia were both most pronounced in the lambs inoculated at six weeks old. The half-life of antibodies to E phagocytophila was estimated to be 17.5 days. Lambs inoculated with tick-borne fever (TBF) had lower liveweights in the autumn than TBF-free controls. |
