Role of YadA, Ail, and Lipopolysaccharide in Serum Resistance of Yersinia enterocolitica Serotype O:3.
Complement attack is a host strategy leading to elimination of pathogens. Yersinia enterocolitica expresses several potential complement resistance factors: the outer membrane proteins YadA and Ail as well as lipopolysaccharide (LPS). To study the contribution of these factors to the survival of Y. enterocolitica serotype O:3 in nonimmune human serum, we constructed 23 mutant strains of Y. ente...
متن کاملRegulation of htrA expression in Yersinia enterocolitica.
In Escherichia coli, envelope stress is regulated by the alternative sigma factor sigma(E) and the two-component regulatory system CpxRA. Both systems overlap in the transcriptional regulation of the htrA gene encoding a protease that degrades misfolded proteins in the periplasm. In Yersinia enterocolitica, HtrA is important for intracellular survival and full virulence in animal models. Here w...

متن کاملPyomyositis caused by Yersinia enterocolitica.
Yersinia enterocolitica is known to be associated with gastroenteritis in children and Reiter's syndrome in adults, but it has only rarely been the cause of primary soft tissue infections. A patient with diabetes mellitus developed a calf abscess, from which Y. enterocolitica was isolated in pure culture. Incision, drainage, and intravenous gentamicin therapy resulted in cure.
متن کاملReal-time TaqMan PCR for Yersinia enterocolitica detection based on the ail and foxA genes.
Yersinia enterocolitica, a cause of emerging enteric infections, is a foodborne pathogen associated with various enteric and systemic syndromes, e.g., diarrhea, enteritis, and enterocolitis. Therefore, the detection of this pathogen has important significance. Previous real-time PCR for detection of Y. enterocolitica was primarily based on the ail gene; biotype 1A nonpathogenic strains were not...
