ESR undertakes a variety of research activities into the epidemiology of infectious disease and specialist aspects of disease-causing organisms.

Recent and ongoing research activities include:

  • determination of the diversity in vaccine target sites on meningococci causing epidemic disease;
  • comparison of New Zealand and overseas isolates of Salmonella Typhimurium DT160 using suppression subtractive hybridisation;
  • analysis of Campylobacter and Burkholderia populations using multilocus sequence typing;
  • use of reverse genetics for the production of vaccine seed strains;
  • occurrence, circulation and evolution of oral poliovirus vaccine strains in New Zealand;
  • prevalence, persistence and localisation of norovirus in shellfish;
  • survival and persistence of norovirus, adenovirus and hepatitis A on fresh produce;
  • detection of noroviruses and animal calciviruses in faecal specimens and environmental waters;
  • risk-targeted study of influenza zoonosis;
  • examination of microdiversities in the 'epidemic meningococcal disease strain' that are associated with geographic source, time, place, disease clustering or immunisation status;
  • determination of diversity in pertussis toxin and pertactin genes in Bordetella pertussis;
  • genetic diversity in group A streptococci causing invasive disease relative to M (emm) types.
