pubmed:abstractText |
The invasin protein of Yersinia pseudotuberculosis binds to integrin receptors on mammalian cells and promotes cellular penetration. We demonstrate here that the cell attachment activity of invasin can be detected in bacterial colonies that have been immobilized on filter membranes. Invasin expressed in either Escherichia coli K-12 or Y. pseudotuberculosis mediated binding to membranes, and as few as 10(5) Y. pseudotuberculosis resulted in detectable attachment of cultured epithelial cells. A similar binding activity was detected in clinical isolates of the related pathogen Y. enterocolitica but not in environmental isolates. Although there exist multiple mechanisms for the binding of wild-type organisms to host cells, efficient mammalian cell binding to immobilized Y. pseudotuberculosis required expression of a functional invasin protein. Several pathogens that are known to bind or penetrate mammalian cells were also tested, and only one of these bound cultured mammalian cells efficiently.
