| leishmaniasis tegumentaria diffusa | Leishmaniasis caused by several New and Old World species and strains of Leishmania (L. Mexicana amazonensis, L. M. Pifanoi, possibly L. M. Garnhami and L. M. Venezuelensis; in Ethiopia, L. Aethiopica, and unidentified leishmanial agents in Namibia and Tanzania). The condition is associated with a suppressed cell-mediated immune response, so that the non-ulcerating, non-necrotizing cutaneous lesions can spread widely over the body; great numbers of parasite-filled macrophages are found in the dermal lesions. Healing does not appear to occur unless an acquired cellular hypersensitivity can develop. Synonym: anergic leishmaniasis, diffuse leishmaniasis, disseminated cutaneous leishmaniasis, leishmaniasis tegumentaria diffusa, pseudolepromatous leishmaniasis. (05 Mar 2000) |

| leishmaniasis, cutaneous | An endemic disease that is characterised by the development of single or multiple localised lesions on exposed areas of skin that typically ulcerate. The disease has been divided into old and new world forms. Old world leishmaniasis is separated into three distinct types according to epidemiology and clinical manifestations and is caused by species of the l. Tropica and l. Aethiopica complexes as well as by species of the l. Major genus. New world leishmaniasis, also called american leishmaniasis, occurs in south and central america and is caused by species of the l. Mexicana or l. Braziliensis complexes. (12 Dec 1998) |
| leishmaniasis, diffuse cutaneous | A form of leishmaniasis, cutaneous caused by leishmania aethiopica in ethiopia and kenya, l. Pifanoi in venezuela, l. Braziliensis in south america, and l. Mexicana in central america. This disease is characterised by massive dissemination of skin lesions without visceral involvement. (12 Dec 1998) |
| leishmaniasis, mucocutaneous | A disease characterised by the chronic, progressive spread of lesions from new world cutaneous leishmaniasis caused by species of the l. Braziliensis complex to the nasal, pharyngeal, and buccal mucosa some time after the appearance of the initial cutaneous lesion. Nasal obstruction and epistaxis are frequent presenting symptoms. (12 Dec 1998) |
| leishmaniasis, visceral | A chronic disease caused by leishmania donovani and transmitted by the bite of several sandflies of the genera phlebotomus and lutzomyia. It is commonly characterised by fever, chills, vomiting, anaemia, hepatosplenomegaly, leukopenia, hypergammaglobulinaemia, emaciation, and an earth-gray colour of the skin. The disease is classified into three main types according to geographic distribution: indian, mediterranean (or infantile), and african. (12 Dec 1998) |
| leishmaniavirus | A genus of RNA protozoan viruses of the family totiviridae. Several different strains of leishmania are infected by a variety of viral species. The type species is leishmania RNA virus 1-1. (12 Dec 1998) |
