title: Studies on Theileriidae (Sporozoa) in Tanzania. I. Tick transmission of Haematoxenus veliferus.
abstract: Haematoxenus veliferus was experimentally transmitted in cattle on two occasions by the tick Amblyomma variegatum; transmission was transstadial, from nymph to adult. Theileria mutans and Cowdria ruminatium were transmitted at the same time. H. veliferus infected at least 15% of red cells in a splenectomized steer and 10% in a normal steer. One experiment on transstadial transmission from larva to nymph was unsuccessful.
