Operon Coordination in Different Bacterial Hosts

Bacterial Disease in Diverse Hosts

teria, often in response to contacting host cells or host Department of Biochemistry and Molecular Biology factors (often called “contact-mediated” secretion) (reDepartment of Microbiology and Immunology viewed by Hueck, 1998). Remarkably, type III systems University of British Columbia also transport specific virulence factors directly into Vancouver, British Columbia host cells, acting as a s...

ospC diversity in Borrelia burgdorferi: different hosts are different niches.

The outer surface protein C (ospC) locus of the Lyme disease bacterium, Borrelia burgdorferi, is at least an order of magnitude more variable than other genes in the species. This variation is classified into 22 ospC major groups, 15 of which are found in the northeastern United States. The frequency distributions of ospC within populations suggest that this locus is under balancing selection. ...

Bacterial endophytes and their interactions with hosts.

Recent molecular studies on endophytic bacterial diversity have revealed a large richness of species. Endophytes promote plant growth and yield, suppress pathogens, may help to remove contaminants, solubilize phosphate, or contribute assimilable nitrogen to plants. Some endophytes are seedborne, but others have mechanisms to colonize the plants that are being studied. Bacterial mutants unable t...

Comparative Study of L-asparaginase Activity in Different Bacterial Species

M13 virus based detection of bacterial infections in living hosts.

We report a first method for using M13 bacteriophage as a multifunctional scaffold for optically imaging bacterial infections in vivo. We demonstrate that M13 virus conjugated with hundreds of dye molecules (M13-Dye) can target and distinguish pathogenic infections of F-pili expressing and F-negative strains of E. coli. Further, in order to tune this M13-Dye complex suitable for targeting other...
