Epizootic lymphangitis is a debilitating fungal disease seen mainly in equids. The most common form of this disease is an ulcerative, suppurative, spreading dermatitis and lymphangitis; however, other forms including pneumonia or ulcerative conjunctivitis also occur. Epizootic lymphangitis spreads most readily where large numbers of animals are assembled, and it was a serious problem during the early twentieth century when large numbers of horses were stabled together. This disease continues to be a significant concern in some countries such as Ethiopia, where the prevalence in carthorses is nearly 19%, and economic losses from this disease are high.
