ASSAY FOR ANTIBODIES TO MYCOBACTERIUM PARATUBERCULOSIS

摘要

A method of detecting an immune response to a paratuberculosis- specific antigen, comprising incubating a sample from a subject with the paratuberculosis-specific antigen and detecting the presence of an antibody in the sample as an indication of an immune response to the paratuberculosis- specific antigen. The antigen may be obtained from a novel M. parat?berc?losis strain JTC303. The antigen may be obtained from the JTC303 culture filtrate. Also provided are antibodies to the paratuberculosis- specific antigen, and a diagnostic kit for the detection of an immune response to a paratuberculosis-specific antigen in a mammal.
