title: Studies on Theileriidae (Sporozoa) in Tanzania. II. Serological characterization of Haematoxenus veliferus.
abstract: Piroplasm antigen of Haematoxenus veliferus, prepared from cattle with a high parasitaemia, showed the presence of antibodies to this parasite in infected animals, using the indirect fluorescent antibody test. A positive titre may persist for at least 4 months, and marginal titres for at least 8 months. There was no cross-reaction in the IFA test with either T. parva or T. mutans.
