regulation of icsp, the outer membrane protease of the shigella actin tail assembly protein icsa, by virulence plasmid regulators virf and virb.	the shigella outer membrane protease icsp removes the actin assembly protein icsa from the bacterial surface, and consequently modulates shigella actin-based motility and cell-to-cell spread. here, we demonstrate that icsp expression is undetectable in mutants lacking either of two transcriptional activators, virf and virb. in wild-type shigella spp., virb expression is entirely dependent on virf; therefore, to circumvent this regulatory cascade, we independently expressed virf or virb in shigel ...	2004	14729695
virulence protein export systems in salmonella and shigella: a new family or lost relatives?	a number of gram-negative bacterial pathogens secrete 'virulence determinants' directly into the extracellular medium, where they interact with host cells to promote disease. the study of the secretion machinery used by these organisms to transport specific virulence determinants out to the cell surface and beyond is of growing importance in the field of bacterial pathogenesis. elements of the secretion machinery are shared by several pathogens. these homologous elements may lead to a better und ...	1994	14731663
analysis of the lambdoid prophage element e14 in the e. coli k-12 genome.	many sequenced bacterial genomes harbor phage-like elements or cryptic prophages. these elements have been implicated in pathogenesis, serotype conversion and phage immunity. the e14 element is a defective lambdoid prophage element present at 25 min in the e. coli k-12 genome. this prophage encodes important functional genes such as lit (t4 exclusion), mcra (modified cytosine restriction activity) and pin (recombinase).	2004	14733619
picu, a second serine protease autotransporter of uropathogenic escherichia coli.	escherichia coli is the major aetiological agent of urinary tract infections (uti). like diarrhoeagenic strains of e. coli, uropathogenic isolates possess virulence determinants that distinguish them from commensal strains and allow them to produce the clinical manifestations associated with uti. several autotransporter proteins have been associated with the ability of e. coli, and other gram-negative bacteria, to cause disease. recently, we described the existence within uropathogenic e. coli ( ...	2004	14734168
