Virulence of Yersinia ruckeri serotype I strains is associated with a heat sensitive factor (HSF) in cell extracts.

Abstract

Cell extracts of Yersinia ruckeri (serotype I) were examined by SDS-PAGE and Western blotting. An unusual band, termed heat-sensitive factor (HSF) was observed in extracts of virulent strains only. It is thought to be lipid in nature; no differences could be detected in the region of the band in protein profiles of virulent and avirulent strains. When trout were infected either by intraperitoneal injection or bath immersion, mortalities occurred only with HSF+ strains. The HSF appears to be an important virulence determinant of Y. ruckeri.
