Bacteria

Bacteria are single celled prokaryotic (no membrane around nucleus) microorganisms that are either free-living in soil or water or diseases of plants or animals. As a disease of plants and animals bacteria are a risk for Western Australian primary producers as they impact upon market access and agricultural production.

WA is free from some of the world's major bacterial diseases. Biosecurity measures on your property are vital in preventing the spread of bacterial diseases.

The Department of Primary Industries and Regional Development provides:

  • biosecurity/quarantine measures at the WA border to prevent the entry of bacterial diseases
  • where relevant post border biosecurity measures
  • advice on widespread bacterial diseases present in the state.

For advice on bacterial diseases search our website, the Western Australian Organism List or contact our Pest and Disease Information Service (PaDIS).

For diagnostic services, please contact our Diagnostic Laboratory Services.
