Research interests

  • Assessing the distribution and persistence of bacterial pathogens, in particular Mycobacterium avium subsp. paratuberculosis in the natural environment.
  • Detection of mycobacteria using molecular techniques such as quantitative real-time PCR
  • Assessing the structure and environmental distribution/significance of bacterial mobile genetic elements such as plasmids and transposable genetic elements.
  • Bacterial starvation-survival strategies and the non-culturable-but-viable condition (with specific reference to the fish pathogen Aeromonas salmonicida).
  • Understanding plasmid-encoded antibiotic resistance carried by incompatability group U (IncU) plasmids.
