St George Disease

Pimelea Trichostachya Poisoning

St George disease is another name for pimelea trichostachya poisoning, which is caused by the consumption of Pimelea trichostachya plants. Two separate cases of poisoning were reported in horses and cattle living in Australia. Both incidents involved pastures overrun with Pimelea species of plants.

The first case of St george disease that was reported in horses occurred in South Australia in 2002, followed by an outbreak in a herd of 10 horses in southern inland Queensland in October-November 2005.
