Freshwater Turtle Disease Notification

   A virus, previously identified as the cause of death of a large proportion of critically endangered Bellinger River Snapping Turtle (Wollumbinia georgesi; 2015 BRST event) population in 2015, has been detected in a collection of captive Australian freshwater turtles in Queensland. 

The affected captive freshwater turtles showed signs of disease and death similar to those seen in the 2015 BRST event. A disease investigation was suggested by the owner and undertaken in collaboration with a local Private Veterinary Practitioner (PVP) and reptile disease specialists. The investigation identified the Bellinger River Virus and another novel nidovirus in sick captive freshwater turtles. The viruses were also detected in a number of apparently healthy animals. The owner and investigators are working in collaboration with government authorities in response to this concerning detection, including investigation into the possible source of the virus. The multi-agency response team is continuing to investigate this event and includes biosecurity and environment government agencies in New South Wales and Queensland.

Flying-fox event in northern NSW & South East Qld

   Dec 2020/Jan 2021: Sick flying-foxes have been reported since mid-December in a range of locations in northern NSW and South East Qld. Clinical signs include paralysis and paresis (limb weakness), protruding tongues, inability to swallow, and difficulty breathing. A small number of cases with similar signs were reported earlier in 2020 but no cause was identified. Carers, veterinarians and government agencies are working to investigate the cause of this event.
 
Wildlife Health Australia is collecting information to better understand the geographic range, species and age of animals affected, and range of clinical signs. If you have information on this event, please fill out the Flying-fox Event Report Form and return it to WHA. If you are working with others, it would be helpful if you could fill out the form together to avoid duplication of information.
 
Please note that WHA is NOT able to receive samples. If you are interested in submitting samples for diagnostic investigation, please contact a veterinarian or the WHA Coordinator in your state or territory.
 
Members of the public should not handle flying-foxes due to the risk of exposure to diseases such as Australian bat lyssavirus. If you find a sick, injured or abandoned flying-fox:
 
  • In NSW: call a licensed wildlife rehabilitation group or local veterinarian. See the NSW DPIE website for further advice and to find your local rehabilitation group.
  • In Queensland: call the RSPCA on 1300 ANIMAL (1300 264 625). See the Qld DES website for further advice.

Canine ehrlichiosis in Australia

   Australia was previously believed to be free of Ehrlichia canis. During 2020, the organism was detected in Australian dogs for the first time in northern Western Australia and the Northern Territory. The disease (also known as canine monocytic ehrlichiosis) can cause serious illness and death in dogs, dingoes and other canids (e.g. foxes). It is transmitted through tick bites, especially the brown dog tick (Rhipicephalus sanguineus) which are generally associated with tropical and subtropical environments. 

For further information, please see:
 

Infection with E. canis (ehrlichiosis) is a notifiable disease in Australia. If you suspect ehrlichiosis in dogs in Australia, please contact your local vet or the national Emergency Animal Disease Watch hotline on 1800 675 888.

Lorikeet paralysis syndrome NSW & Qld

  
Lorikeet paralysis syndrome is a seasonal syndrome which has been occurring in eastern Australia for a number of years. This summer there has been a particularly high number of cases in northern NSW and southern Queensland.
 
The syndrome primarily affects rainbow lorikeets (Trichoglossus haematodus) but has also been reported in scaly-breasted lorikeets (Trichoglossus chlorolepidotus). Affected birds are unable to fly, with varying degrees of paralysis of the hindlimbs. In more severe cases the paralysis may affect the whole body and the bird may be unable to blink or swallow, and have a significant change to the voice. Less severely affected birds may recover with supportive treatment.
 
Wildlife disease experts have been investigating this syndrome and a wide range of tests have been done. The current investigation has found no evidence of an infectious disease as the cause of this syndrome. The possibility of an environmental or plant toxin is being investigated.
 
Members of the public who see a sick lorikeet should:
  • In NSW: call a licensed wildlife rehabilitation group or local veterinarian. See the NSW DPIE website for further advice.
  • In Queensland: call the RSPCA on 1300 ANIMAL (1300 264 625). See the Qld DES website for further advice.

African Swine fever and Feral Pigs

  
Members of the wildlife community should be alert to signs of disease in Australian feral pigs. 

African swine fever (ASF) is a highly contagious viral disease of feral (wild) and domestic pigs. It has established itself in Asia and parts of Europe and continues to spread. ASF has no vaccine and kills about 80 per cent of the pigs it infects. Due to its high economic impact and lack of a commercially available vaccine, ASF is considered one of the most important diseases of pigs worldwide and is listed as a disease of international significance by the OIE World Organisation for Animal Health.

ASF has never occurred in Australia. However, it has been reported in other areas of the world and most recently in Timor Leste. Its changing distribution means that it is a significant biosecurity threat to Australia. An outbreak would have significant impacts on pig production and health. It would also damage Australia’s trade and the economy.

Signs that are seen in infected pigs can be variable but include red, blotchy or black skin lesions; nose and eye discharge; coughing or difficulty breathing; incoordination; convulsions; abortions. Sudden death can also occur with no prior signs of disease.

We are requesting that all members of the wildlife community be alert (not alarmed) and if you see signs of disease in feral pigs (or domestic pigs) phone the Emergency Animal Disease Watch Hotline on 1800 675 888 immediately. This will put you in touch with your state or territory animal health authority. Suspect cases of ASF must be reported to animal health authorities.

Signs that are seen in infected pigs can be variable but include red, blotchy or black skin lesions; nose and eye discharge; coughing or difficulty breathing; incoordination; convulsions; abortions. Sudden death can also occur with no prior signs of disease.

ASF spreads easily by direct contact between pigs or indirectly by contaminated items including feed, feed ingredients, equipment, vehicles, clothing and footwear. It can also be spread through meat from infected animals, and vectors (such as some ticks). If you locate a sick, dead or suspect animal call the Emergency Animal Disease Watch Hotline immediately and they will advise on appropriate hygiene protocols.

Neurological syndrome in brushtail possums, Tasmania

   Brushtail possums presenting with neurological signs are being investigated in Tasmania. Signs in affected possums include docility, out during daylight, difficulty climbing, gait abnormalities, tremors, head tilt, circling, uncoordinated movement, and signs of visual impairment or blindness. These signs are consistent with “wobbly possum disease”, which was first discovered in brushtail possums in New Zealand, where a nidovirus has been identified as the causative agent. Recent testing of the Tasmanian cases has identified a nidovirus that is very similar to the NZ virus. Investigations into this event are continuing.

For more information (including biosecurity advice for Tasmanian rehabilitators) see the DPIPWE website, and the WHA Fact Sheet.

Skin disease in free-living Eastern water dragons in Southeast Queensland

  
An outbreak of severe, proliferative skin disease has been detected in free-living Eastern water dragons (Intellagama lesueurii) in Southeast Queensland, Australia. The disease has been confirmed in Eastern water dragon populations at multiple locations across Brisbane City. In each case so far, the diagnosis has been based on skin changes and confirmed by PCR and culture. The causative organism identified in each case belongs to the genus Nannizziopsis. Until recently, reports of infection with Nannizziopsis have been restricted to captive animals.

Nannizziopsis is known to cause fatal disease in a wide range of reptiles. The infection is contagious through physical contact and through the environment, therefore best practice biosecurity measures are recommended.

The following notification outlines what to be on the look for, what information to collect and who to contact if you come across a suspect case. Further information is also available via the WHA fact sheet: Yellow Fungus and Related Diseases in Australian Reptiles. Note: This notification has been developed by the researchers investigating outbreak, in consultation with relevant government agencies, and has been circulated directly to veterinary hospitals, wildlife care groups and local councils in SE Qld and nationally to WHA surveillance partners.

How you can help: If you come across any suspect cases, we encourage you to contact the researchers investigating this event and cc’ your State/Territory WHA Coordinator and Environment Representative, especially if the case(s) is outside SE Queensland.

Tularaemia

 

    

Tularaemia is an infection caused by the bacteria Francisella tularensis. It is commonly found in a range of wildlife species across the northern hemisphere but, until recently, was believed to be absent from Australian wildlife.

Different subspecies of tularaemia vary in their virulence. A single case of Francisella tularensis novicida was reported in a human in the Northern Territory in 2003. In 2011, two separate cases of F. t. holarctica biovar japonica were diagnosed in two women who had a history which included being scratched and/ or bitten by common ringtail possums in western Tasmania. Testing of a small number of possums from western Tasmania and other areas did not reveal evidence of tularaemia.

In September 2016, tularaemia was detected for the first time in Australian animals, following Next Generation molecular analysis of archived samples, collected from two separate clusters of common ringtail possum deaths that had occurred in NSW in 2002 and 2003. Findings of F. t. holarctica were confirmed by PCR and were found to be genomically very similar to that found in the 2011 Australian human cases.
