Tammar Wallaby

The Tammar Wallaby (Macropus eugenii), also known as the Dama Wallaby or Darma Wallaby, is a small member of the kangaroo family and is the type species for research on kangaroos and marsupials.
It is found on offshore islands on the South Australian and Western Australian coast. It persists in large numbers on Kangaroo Island, where it seasonally breeds in large numbers and can become a problem to farmers through competition for pasture and grain crops. High densities of these animals also has impact on the density of low vegetation across the Island.
The Tammar Wallaby was seen on West Wallabi Island in the Houtman Abrolhos off Western Australia by survivors of the 1628 Batavia shipwreck, and recorded by Francisco Pelsart in his 1629 Ongeluckige Voyagie. This represents the first recorded sighting of a macropod by Europeans, and probably also the first sighting of an Australian mammal.
Australian scientists, lead by Dr. Ben Cocks, have found a compound in the milk of the Tammar Wallaby called AGG01 which has the potential to be a new and powerful form of antibiotic. AGG01 is a protein and in laboratory testing AGG01 has been 100 times more effective than penicillin, killing over 99% of the pathogenic bacteria (both gram-positive and gram–negative) and fungus that it was incubated with, including Salmonella, Proteus vulgaris and golden staphylococcus.
