Salmonellae bacteria were detected in 4,881 badgers and 613 other wild animals in Cornwall over 14 years. This study identified 26 salmonellae serotypes in badgers and 4 in other wild species.

Area of Science:

  • Veterinary Microbiology
  • Wildlife Epidemiology
  • Zoonotic Disease Surveillance

Background:

  • Wild animals can act as reservoirs for bacterial pathogens.
  • Salmonellosis poses a risk to wildlife health and can potentially transmit to livestock and humans.
  • Understanding pathogen prevalence in free-living animals is crucial for public health.

Purpose of the Study:

  • To investigate the prevalence and diversity of Salmonella in free-living wild animals in Cornwall.
  • To identify specific Salmonella serotypes circulating in badger populations and other wild species.
  • To assess the potential role of wildlife in Salmonella transmission dynamics.

Main Methods:

  • Longitudinal study conducted over 14 years in Cornwall.
  • Bacteriological examination of 4,881 badgers and 613 other wild mammals and birds (15 mammal and 30 bird species).

  • Isolation and serotyping of Salmonella strains.

    • Main Results:

    • Salmonellae were isolated from badgers and other wild species.
    • Twenty-six distinct Salmonella serotypes and one non-motile strain were identified in badgers.
    • Four Salmonella serotypes were detected in the other wild animal species examined.

    Conclusions:

    • Wild badgers and other free-living animals in Cornwall harbor diverse Salmonella serotypes.
    • These findings highlight the importance of wildlife surveillance for zoonotic pathogens.
    • Further research is warranted to understand the ecological role and transmission pathways of Salmonella in wildlife.
