Veterinary Microbiology and Pathology

Program in Genomics


Kelly A. Brayton and Douglas R. Call


  • Encourage interdisciplinary collaborations and graduate and post-graduate research opportunities.
  • Examine genetic diversity as it relates to differential survivorship and virulence.
  • Identify mechanisms responsible for generating genetic diversity.
  • Develop new tools for diagnostics and strategies for pathogen control and intervention

Program accomplishments

  • Whole genome comparative analysis of Anaplasma marginale strains
  • Genome sequences for attenuated and virulent strains of Babesia bovis
  • Genome sequences for Mannheimia haemolytica
  • Optical mapping of EHEC genotypes
  • Developed mixed-genome and mixed-plasmid microarrays to study molecular epidemiology of food-borne pathogens and antibiotic resistance traits.
  • Developing arrays suitable for simultaneous detection of multiple pathogens.

Example of genomic hybridizations for two strains of L. monocytogenes (serotypes 1/2a, top and 4b, bottom). Only a portion of the full array is shown. Spots clearly visible indicate presence of target. Missing spots are attributable to absent or highly diverged sequence (e.g., column 1, row 4).
