Intravenous Infection of Dromedary Camels with Anaplasma marginale

Three dromedary camels were infected with the Rickettsia, Anaplasma marginale. One American Type Culture Collection strain was intravenously injected into the jugular veins of two adult dromedary camels. Additionally, EDTA blood from a bovine bull naturally infected with Anaplasma marginale was also intravenously injected into the jugular vein of a third camel. All three camels were tested for A. marginale using PCR, Giemsa staining and serology. All tests were negative and the dromedary camels remained healthy throughout the study.
