title: Lymphoid thyroiditis following immunization with group A streptococcal vaccine.
abstract: Severe lymphoid thyroiditis and associated hypothyroidism occurred in all of 7 male and 4 female F(7) derivatives (seventh generation) of rats immunized in each generation against Group A streptococci. This evidence of thyroiditis produced by immunization against a nonthyroidal antigen suggests that some cases of Hashimoto's thyroiditis in humans may result from nonspecific immune responses.
