The anginal form of yersiniosis is described in 16 patients (1.3% of all patients with this kind of infection). Clinico-laboratory investigations revealed signs of a generalized process with bacteremia and toxemia. The syndrome complex of infectious mononucleosis is often observed in this form of yersiniosis. Two patients showed a diphtheria-like form of severe angina. In 31% of patients recurrence developed but usually without angina. The outcomes are favourable.
