What Is Buruli Ulcer?

What Causes It?

As stated, Buruli ulcer is caused by Mycobacterium ulcerans, which produces a toxin that inhibits the immune system, allowing it to spread and cause mass tissue damage.

The exact mode of transmission of the bacterium is currently unknown. However, there is a possibility the disease may be transmitted to humans by certain insects that live in water. There is currently no known link between human and animal transmission of the disease, but some animals can get Buruli ulcer. In fact, laboratory research in Australia has confirmed Buruli ulcer in animals including horses, canines, alpacas, koalas, and opossums.
