Leishmaniasis is a longterm, severe, protozoal disease of humans, dogs, and certain rodents. It is characterized by skin sores, disease of the lymph nodes, weight loss, anemia, lameness, kidney failure, and occasionally nosebleed or eye inflammation. Infection in dogs occurs in Central and South America, the Middle East, Asia, and in the Mediterranean region. Cats and other domestic animals are rarely infected and usually only develop skin ulcers, without showing other signs of disease (see Disorders Affecting Multiple Body Systems of Dogs: Leishmaniasis (Visceral Leishmaniasis) in Dogs).
