New and emerging canine tick-borne diseases in Australia: Ehrlichiosis and an update on hepatozoonosis

The discovery in 2020 of the notifiable disease canine monocytic ehrlichiosis (CME), caused by Ehrlichia canis, in tropical regions of Western Australia and the Northern Territory, has serious implications for the health of Australian dogs. This rickettsial organism is transmitted shortly after attachment by the brown dog tick (Rhipicephalus sanguineus) and causes fever, anorexia, lethargy, severe bleeding (especially epistaxis), lymphadenomegaly and splenomegaly. Pancytopenia is a fatal consequence of chronic infections. This presentation will provide an overview and advice about the diagnosis and treatment of CME, together with important information about tick prevention. A second newly discovered tick-borne parasite, Hepatozoon canis, will also be discussed. 

This webinar counts for one (1) CE point.

Prof Peter Irwin

I was appointed Principal of the College of Veterinary Medicine in August 2014. Originally I was a graduate of the Royal Veterinary College, London University (1982) and completed my PhD at James Cook University. I joined Murdoch University in 1998 as a Senior Lecturer in Small Animal Medicine, after an academic position at the Vet School at Universiti Putra Malaysia (in Kuala Lumpur) and completing a residency and registrar appointment at the Veterinary Clinical Centre, University of Melbourne.  I’m a combination of veterinary clinician (and registered as a specialist in canine medicine) and veterinary parasitologist – most of my teaching and clinical service has been in companion animal science and all of my research in to do with vector-borne diseases.

In my role as Principal I am responsible for the professional, ethical, and academic affairs of the College of Veterinary Medicine.  Additionally I am currently Program Chair of the postgraduate coursework program in Small Animal Practice (Masters) and I co-supervise clinical residencies and research degrees.  My clinical interests include infectious and parasitic diseases of dogs and cats and my research is predominantly concerned with vector-borne diseases of animals and people.
