''Leishmania spp.'' are intracellular parasites of [[Macrophage|macrophages]] from the same family as ''[[Trypanosoma]] spp.''. These organisms parasitise human, dogs and wild animals throughout southern Europe, Africa, Asia and South America. The infection is transmitted by [[Psychodidae|sandflies]]. Infection can cause both cutaneous and visceral disease. Clinical disease cause by ''Leishmania'' is termed Leishmaniasis. Three types of ''Leishmania spp.'' are described;

# '''Hypopylaria''' - found in lizards that ingest the sandfly intermediate host. Development occurs in the hindgut of the fly.

Chemotherapy can be used to treat dogs with leishmaniasis; however this will not eliminate the infection completely. It may appear to resolve the infection, but it is not uncommon for clinical sign to return later in the dog's life. It is important to factor in the risks involved with chemotherapy, such as suppression of the immune system, and the expense of prolonged treatment.
