The development of Salmonella vaccine vectors has been hindered by both the requirement for multiple doses to induce immune responses and a lack of plasmid stability. Direct comparisons of different promoter systems with the same antigen are necessary to address these important issues. We have previously described an AroA- AroD- deletion mutant of Salmonella typhimurium (GID101) which expresses...
Pseudomonas aeruginosa bacteremia in cancer patients develops from initial gastrointestinal (GI) colonization with translocation into the bloodstream in the setting of chemotherapy-induced neutropenia and GI mucosal damage. We established a reproducible mouse model of P. aeruginosa GI colonization and systemic spread during neutropenia. Mice received 2 mg of streptomycin/ml of drinking water an...
Allelic forms (Tams1-1 and Tams1-2) of the major merozoite surface antigen gene of Theileria annulata have recently been expressed in Escherichia coli and in Salmonella typhimurium aroA vaccine strain SL3261. To test the potential of subunit vaccines against T. annulata infection, we immunized four groups of three calves with either recombinant (re-) (Tams1-1 and Tams1-2) proteins or naked DNA ...
