Glanders (from Middle English glaundres or Old French glandres, both meaning glands; Latin:malleus, German:Rotz; also known as "equinia", "farcy", and "malleus") is an infectious disease that occurs primarily in horses, mules, and donkeys. It can be contracted by other animals, such as dogs, cats, goats and humans. It is caused by infection with the bacterium Burkholderia mallei, usually by ingestion of contaminated feed or water. Signs of glanders include the formation of nodular lesions in the lungs and ulceration of the mucous membranes in the upper respiratory tract. The acute form results in coughing, fever, and the release of an infectious nasal discharge, followed by septicaemia and death within days. In the chronic form, nasal and subcutaneous nodules develop, eventually ulcerating. Death can occur within months, while survivors act as carriers.
