RESUMO

rpoS, a gene that encodes an alternative sigma factor (also known as katF), is critical for the ability of Yersinia enterocolitica grown at 37 degrees C, but not at 26 degrees C, to survive diverse environmental insults such as high temperature, hydrogen peroxide, osmolarity, and low pH. However, a Y. enterocolitica rpoS mutant was not affected in expression of inv or ail, invasion of tissue culture cells, or virulence in mice.
