| isolation of a virulent strain of ehrlichia phagocytophila from the blood of cattle in the isle of man. | a blood sample from a cow in the isle of man caused a severe ehrlichia phagocytophila infection when inoculated into a splenectomised calf. the parasite was passaged successively into a further splenectomised calf and then into two intact animals. one of the splenectomised calves and one of the intact animals died of the infection which was characterised by causing a sustained febrile response apparently correlated with a marked invasion of monocytes by the rickettsiae. | 1978 | 676008 |
