Could toxoplasmosis have a role in mammal declines?
Toxoplasmosis was introduced to Australia by cats, who continue to spread the disease. It is known that the disease affects Australian mammals, and that many Australian mammals are suffering dramatic declines. It was completely unknown, however, whether these declines are linked with toxoplasmosis. Dr Nelika Hughes from The University of Melbourne investigated Toxoplasma gondii prevalence across Australia and whether it has played a role in mammal declines.
