Abstract
A purified antigenic surface protein of Anaplasma marginale has been identified, and is capable of inducing immune responses in ruminants which neutralizes virulent Anaplasma marginale. The antigenic surface protein has a molecular weight of about 105,000 daltons, and can be purified by an immunoaffinity chromatography process. The antigen has further utility in diagnostic tests for anaplasmosis. It can be synthesized by polypeptide procedures or by genetic engineering. DNA and amino acid sequences have been developed for the antigen according to this invention. The antigen is useful as a vaccine component for protecting mammals against infection by Anaplasma marginale and may be useful for rickettsial organisms other than Anaplasma marginale.
