[The mononuclear syndrome in yersiniosis and pseudotuberculosis].

As many as 95 patients with generalized form of yersiniosis and 66 patients with scarlatiniform pseudotuberculosis were examined. Atypical mononuclears were detected in the peripheral blood of 23.2% of patients with yersiniosis and 13.6% of those with pseudotuberculosis. In 83.9% their numbers varied from 2 to 9% and in 16.1% only their count amounted to 10-11%. Clinical symptoms occurring in patients with yersiniosis (fever, changes in the fauces, exanthema, polyadenopathy, affection of the liver) are revealed with varying frequency in infectious mononucleosis. But as far as the condition under consideration is concerned, exanthema occurs in rare cases only; diarrhea, arthralgia, hypertrophy of the lingual papillae are not characteristic of it. Mononuclear reaction of blood of the patients with yersiniosis and pseudotuberculosis was of short duration and was rather weak.
