| pubmed-article:1258136 | pubmed:abstractText | 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. | lld:pubmed |
