The Francisella pathogenicity islandFrancis E Nano
Department of Biochemistry and Microbiology, PO Box 3055 STN CSC, University of Victoria, Victoria B C V8W 3P6 Canada

The Francisella pathogenicity island protein PdpD is required for full virulence and associates with homologues of the type VI secretion systemJagjit S Ludu
Department of Biochemistry and Microbiology, University of Victoria, Victoria, BC V8W 3P6, Canada
J Bacteriol 190:4584-95. 2008..Finally, deletions of FPI genes encoding proteins that are homologues of known components of type VI secretion systems abolished the altered distribution of IglC and the outer membrane localization of PdpD...
A Francisella novicida pdpA mutant exhibits limited intracellular replication and remains associated with the lysosomal marker LAMP-1Crystal L Schmerk
Department of Biochemistry and Microbiology, University of Victoria, Victoria, BC, Canada
Microbiology 155:1498-504. 2009..novicida. The transcriptional response of the host macrophage indicates that PdpA functions directly or indirectly to suppress macrophage ability to signal via growth factors, cytokines and adhesion ligands...
Characterization of the pathogenicity island protein PdpA and its role in the virulence of Francisella novicidaCrystal L Schmerk
Department of Biochemistry and Microbiology, University of Victoria, Victoria, BC, Canada
Microbiology 155:1489-97. 2009..Deletion of pdpA resulted in a strain that was highly attenuated for virulence in chicken embryos and mice...
Essential genes from Arctic bacteria used to construct stable, temperature-sensitive bacterial vaccinesBarry N Duplantis
Department of Biochemistry and Microbiology, University of Victoria, Victoria, BC, V8W 3P6, Canada
Proc Natl Acad Sci U S A 107:13456-60. 2010..These results show that psychrophilic essential genes can be used to create a unique class of bacterial temperature-sensitive vaccines for important human pathogens, such as S. enterica and Mycobacterium tuberculosis...

Department of Biochemistry and Microbiology, PO Box 3055 STN CSC, University of Victoria, Victoria, British Columbia, V8W 3P6, Canada
Infect Immun 74:4809-16. 2006..tularensis appeared to be growing intracellularly. These results demonstrate that infection of 7-day-old chicken embryos can be used to evaluate the virulence of attenuated F. tularensis strains...

Proc Natl Acad Sci U S A 101:4246-9. 2004..Thus, MglA regulates the transcription of virulence factors of F. tularensis that contribute to intramacrophage and intraamoebae survival...
Francisella novicida LPS has greater immunobiological activity in mice than F. tularensis LPS, and contributes to F. novicida murine pathogenesisTara L Kieffer
Laboratory of Mycobacterial Diseases and Cellular Immunity, Division of Bacterial and Parasitic Products, CBER/FDA, 1401 Rockville Pike, HFM 431, Bethesda, Rockville, MD 20852, USA
Microbes Infect 5:397-403. 2003..novicida LPS to stimulate the production of proinflammatory cytokines including TNF-alpha likely contributes to the increased virulence for mice of F. novicida compared to F. tularensis LVS...
