Immunoblot can be used as an adjunct tool in the diagnosis of Yersinia enterocolitica infection. The presence of IgA and IgG antibodies to Y. enterocolitica Yop proteins can also aid in the diagnosis of post-infectious autoimmune disorders associated with Y. enterocolitica (eg, reactive arthritis, erythema nodosum, Graves Disease, and Hashimoto thyroiditis).
