The Alternative Sigma Factor, ςE, Is Critically Important for the Virulence of Salmonella typhimurium

Humphreys, Sue, Stevenson, Andrew, Bacon, Andrew, Weinhardt, A. Barbara, Roberts, Mark

In Escherichia coli, extracytoplasmic stress is partially controlled by the alternative sigma factor, RpoE (ςE). In response to environmental stress or alteration in the protein content of the cell...

Prior Immunity to Homologous and Heterologous Salmonella Serotypes Suppresses Local and Systemic Anti-Fragment C Antibody Responses and Protection from Tetanus Toxin in Mice Immunized with Salmonella Strains Expressing Fragment C

Roberts, Mark, Bacon, Andrew, Li, Jingli, Chatfield, Steven

We have investigated the effect of preexisting immunity to homologous (Salmonella typhimurium) or heterologous (S. dublin) serotypes of Salmonella on the ability of an attenuated S. typhimurium aroA...

Comparison of Abilities of Salmonella enterica Serovar Typhimurium aroA aroD and aroA htrA Mutants To Act as Live Vectors

Roberts, Mark, Chatfield, Steven, Pickard, Derek, Li, Jingli, Bacon, Andrew

We compared the ability of Salmonella enterica serovar Typhimurium SL1344 aroA aroD (BRD509) and aroA htrA (BRD807) mutants to act as live vectors for delivery of fragment C of tetanus toxin (FrgC)....

Oral Vaccination against Tetanus: Comparison of the Immunogenicities of Salmonella Strains Expressing Fragment C from the nirB and htrA Promoters

Roberts, Mark, Li, Jingli, Bacon, Andrew, Chatfield, Steven

We have found the in vivo-regulated nirB promoter (PnirB) to be effective for directing expression of a number of antigens in salmonella in vivo. We wished to determine if other in vivo-regulated...
