Yersinia enterocoliticahas two type III secretion systems (TTSS): The well characterized Ysc-Yop system and the relatively uncharacterized Ysa-Ysp system. Detection of Ysps in culture supernatants has only been observedin vitrowhen cultures are grown at low temperature (26°C) and in high salt (290mM NaCl). Previous reports demonstrated that expression from theysaEpromoter was activated by high salt. In this study, we report a new environmental stimulus forysagene expression; in the presence of high salt, growth on solid surface stimulates expression 7-fold compared to growth in high salt broth. These new data indicate that, in the presence of salt, solid surface is an extremely robust signal for the Ysa system.
