− | Infection with ''Leishmania'' can produce either cutaneous or viscreal disease as the infected macrophages proliferate in foci. There is a very long incubation period from infection to pathology, which can take years and therefore many infected dogs either never become symptomatic or remain so for a long period of time. Even once an animal has been treated for leishmaniasis it is not uncommon for clinical symptoms to recur after a lengthy period of remission. Information on the clinical signs and treatment for disease caused by leishmania can be found on the [[Leishmaniosis]] page. | + | Infection with ''Leishmania'' can produce either cutaneous or viscreal disease as the infected macrophages proliferate in foci.
