Exotic dog disease detection leads to movement restrictions in WA’s north

Beef Central, 09/06/2020

A DISEASE of dogs never before found in Australia has been detected in the Kimberley region of Western Australia, leading to dog movement restrictions being placed on the region.

The Western Australian Department of Primary Industries advises that Ehrlichiosis, a tick-borne disease caused by the bacteria Ehrlichia canis, has been detected in a small number of dogs in the Halls Creek and Kununurra areas of the Kimberley region.

E. canis occurs worldwide, particularly in tropical and subtropical regions, but this is the first time it has been detected in Australia in dogs that are not imported from overseas.

Dog movement conditions

While surveillance is being carried out to determine the distribution of E. canis, conditions for dog movements out of the Kimberley region have been put in place to reduce the spread of the disease. These movement conditions apply to the shires of Broome, Derby-West Kimberley, Halls Creek and Wyndham-East Kimberley.

The Department of Primary Industries says it is liaising with the owners of the dogs and their private veterinarians and will be conducting further surveillance to determine the distribution of the disease. Dogs do not transmit the disease to each other, but transmission is maintained by a cycle of between ticks and dogs.

Ehrlichiosis has three phases: an ‘acute’ phase or early signs of disease, a ‘subclinical phase’ where there are no obvious visible signs of disease, and a ‘chronic’ or long-term stage.

The severity of the disease varies considerably among dogs. The incubation period for the development of acute disease is 1-3 weeks after the tick bite, but the chronic form of ehrlichiosis may not manifest until months or years following infection.

In the acute phase, symptons include fever, lethargy, enlarged lymph nodes, loss of appetite, discharge from the eyes and nose, weight loss and bleeding disorders. In the chronic phase, infected dogs may have increased susceptibility to secondary infections. This form of the disease can be fatal.

Working dogs are considered particularly susceptible, due to the greater likelihood of exposure to tick bite than companion animals.

To help prevent E. canis occurring, WA DPI advises:

  • Maintaining dogs on a tick control program – ask your vet for the most suitable product and application regime.
  • Avoiding taking dogs into tick-infested areas such as the bush where possible.
  • Inspecting dogs for ticks after being in tick-infested areas (especially around the neck, head, ears, armpits and belly) and carefully removing any ticks. Vets can advise on the best methods of tick removal.

    We have lived in broome for years but since I moved to 4 mile area,dogs we have owned have developed diseases that involved skin infections weight loss swelling on neck that had to be drained, odema in belly These dogs were working dogs in breed only. We thought they could be from arachnid family eg mites ticks white tail and other spiders
    They were deticked by washing with medication and by oral medication
    I did ask for leishmaniasis tests as one vet who had worked in Qatar said if it wasnt australia hed say thats what it was but this was refused by the vet in charge even rhough i offered to pay for tesr
    I want more surveillance of
    This disease in kimberley as it exists in Timor and for the right of customers to demand tests for peace of mind as we also developed skin disease that took 2 years to go and only after using doxyxcline
    This was 3 years ago
