Characterizing effect of thermolabile lethal toxin Yersinia Pseudotuberculosis on embryogenesis and biosynthesis of DNA, RNA and protein in embryos of sea urchin Strongylocentrotus Intermedius

Abstract

The paper discusses effect of thermolabile lethal toxin Yersinia pseudotuberculosis on embryogenesis of sea urchins
Strongylocentrotus intermedius and biosynthesis of nucleic acids
and proteins in embryo cells. As shown, the toxin has effect on
metabolic processes in cells by inhibiting synthesis of DNA and
RNA, and almost does not affect protein synthesis. The toxin is of
damaging action on sea urchin embryos in development and causes
morphological changes, thus leading to embryonic death.
