This toxin is characterized by strong toxic action and it can bring on diarrhea in human and animals. The chromosome gene of thermostable enterotoxin ystB was detected by PCR in 87.1% out of 116 studied strains of different origin and territorial isolation. To determine toxin production in vitro the studied strains cultivated in various conditions: in 26°C and 37°С in usual culture medium and in 37°С in the medium corresponded to the content of intestine. In part of the studied strains the toxin production was revealed on the model of newborn mice in both temperature regimes of cultivation 26°С and 37°С. The study of toxin production in representatives of Y. enterocolitica biotype 1А showed their possible role as etiological agents of diarrhea.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Резюме.</bold> Представители Y. enterocolitica биотипа 1А, считающиеся непатогенными микроорганизмами, были изучены на наличие продукции термостабильного энтеротоксина YST B (Yersinia Stable Toxin), который обладает сильным токсичным эффектом и способен вызывать в организме человека и животных диарею.
