Ticked Off: Inside The Ehrlichiosis Epidemic With Dr. Peter Irwin - Part 2
📄 Episode Show Notes
In Part 1 of this series, Dr Liisa Ahlstrom helped us understand what ehrlichiosis is, where it’s spreading across Australia, and why prevention is so different from paralysis tick disease.
In this episode, we take the next step with Professor Peter Irwin, internal medicine specialist and one of Australia’s leading experts on vector-borne disease in dogs. Peter was directly involved in the very first confirmed cases of ehrlichiosis in the Northern Territory back in 2020, and he brings decades of experience in research, teaching, and clinical medicine.
We dive into:
from prevention and epidemiology to the clinic floor and patient care.
