Antigens of Anaplasma centrale, Onderstepoort isolate, and A. marginale, Wacol isolate, were analysed by a Western blotting technique. Sera from A. centrale-infected calves reacted to 41- and 38-kDa antigens in A. centrale and a 41-kDa antigen in A. marginale. Serum collected during the primary reaction from an A. marginale-infected calf reacted only to the 41-kDa antigen of A. marginale; heterologous antibody response to the 41-kDa antigen of A. centrale did occur later during the infection, but remained markedly weaker than the homologous response. The serologic cross-reactivity to this 41-kDa Anaplasma antigen confirms that it is common to the genus and also that it is a heterogeneous complex.

D003429	Cross Reactions	Serological reactions in which an antiserum against one antigen reacts with a non-identical but closely related antigen.	Cross Reaction,Reaction, Cross,Reactions, Cross
D000709	Anaplasma	A genus of gram-negative bacteria whose organisms are obligate parasites of vertebrates. Species are transmitted by arthropod vectors with the host range limited to ruminants. Anaplasma marginale is the most pathogenic species and is the causative agent of severe bovine anaplasmosis.
D000712	Anaplasmosis	A disease usually in cattle caused by parasitization of the red blood cells by bacteria of the genus ANAPLASMA.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
