The HtrA stress response protein has been shown to play a role in the virulence of a number of pathogens. For some organisms, htrA mutants are attenuated in the animal model and can be used as live vaccines. A Yersinia pestis htrA orthologue was identified, cloned and sequenced, showing 86% and 87% similarity to Escherichia coli and Salmonella typhimurium HtrAs. An isogenic Y. pestis htrA mutant was constructed using a reverse genetics approach. In contrast to the wild-type strain, the mutant failed to grow at an elevated temperature of 39 degrees C, but showed only a small increase in sensitivity to oxidative stress and was only partially attenuated in the animal model. However, the mutant exhibited a different protein expression profile to that of the wild-type strain when grown at 28 degrees C to simulate growth in the flea.
