Yersinia enterocolitica antibodies in thyroid disorders

Yersinia enterocolitica agglutinating antibodies were present in 42% of 36 patients with thyroid disease and in none of 77 control subjects. Since the frequency of Yersinia infections in Israel is low, the association of thyroid diseases with Yersinia antibodies is of particular interest. The significance of this finding is discussed in view of some recent observations.
