| anergic leishmaniasis | 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) |

| anthroponotic cutaneous leishmaniasis | A form of Old World cutaneous leishmaniasis, usually with a prolonged incubation period and confined to urban areas. Synonym: chronic cutaneous leishmaniasis, dry cutaneous leishmaniasis, urban cutaneous leishmaniasis. (05 Mar 2000) |
| canine leishmaniasis | A mild infection of dogs, usually confined to the muzzle or ears, produced by human disease-causing species of Leishmania; dogs therefore are important reservoirs of human infection, such as with visceral leishmaniasis in the Mediterranean region. (05 Mar 2000) |
| visceral leishmaniasis | A chronic disease, occurring in India, Assam, China, the area formerly known as the Mediterranean littoral areas, the Middle East, India, Pakistan, China, South and Central America, Asia, Africa caused by Leishmania donovani and transmitted by the bite of an appropriate species of sandfly of the genus Phlebotomus or Lutzomyia; the organisms grow and multiply in macrophages, eventually causing them to burst and liberate amastigote parasites which then invade other macrophages; proliferation of macrophages in the bone marrow causes crowding out of erythroid and myeloid elements, resulting in leukopenia, and anaemia, splenomegaly, and hepatomegaly which are characteristic, along with enlargement of lymph nodes; fever, fatigue, malaise, and secondary infections also occur; different strains of leishmaniasis donovani occur; leishmaniasis infantum in Eurasia, leishmaniasis chagasi in Latin America. Synonym: Assam fever, black sickness, Burdwan fever, cachectic fever, Dumdum fever, kala azar, tropical splenomegaly. (05 Mar 2000) |
| chronic cutaneous leishmaniasis | A form of Old World cutaneous leishmaniasis, usually with a prolonged incubation period and confined to urban areas. Synonym: chronic cutaneous leishmaniasis, dry cutaneous leishmaniasis, urban cutaneous leishmaniasis. (05 Mar 2000) |
| rural cutaneous leishmaniasis | A form of cutaneous leishmaniasis characterised by rural distribution of human cases near infected rodents, particularly communal ground squirrels; characterised by acute rapidly developing dermal lesions that become severely inflamed, with moist necrotizing sores or ulcers that heal in two to eight months after a two to four month incubation period; among nonimmune immigrants, multiple lesions may develop, which heal more slowly and leave disabling or disfiguring scars. A strong delayed hypersensitivity and involvement of immune complexes play a role in necrosis, which is part of the healing process and of the strong specific immunity that follows. Synonym: acute cutaneous leishmaniasis, rural cutaneous leishmaniasis, wet cutaneous leishmaniasis. (05 Mar 2000) |

| mucocutaneous leishmaniasis | A grave disease caused by Leishmania braziliensis braziliensis, endemic in southern Mexico and Central and South America, except for the equatorial region of Chile; the organism does not invade the viscera, and the disease is limited to the skin and mucous membranes, the lesions resembling the sores of cutaneous leishmaniasis caused by L. Mexicana or L. Tropica; the chancrous sores heal after a time, but some months or years later, fungating and eroding forms of ulceration may appear on the tongue and buccal or nasal mucosa; many variants of the disease exist, marked by differences in distribution, vector, epidemiology, and pathology, which suggest that it may in fact be caused by a number of closely related aetiological agents. See: espundia. Synonym: American leishmaniasis, leishmaniasis americana, nasopharyngeal leishmaniasis, New World leishmaniasis. (05 Mar 2000) |
| cutaneous leishmaniasis | Infection with promastigotes (leptomonads) of Leishmania tropica and of leishmaniasis major inoculated into the skin by the bite of an infected sandfly, Phlebotomus (commonly P. Papatasi); it is endemic in parts of Asia Minor, northern Africa, and India, and is known by innumerable names, each indicating its locality (e.g., Aleppo, Baghdad, Delhi, or Jericho boil; Aden ulcer; Biskra button); the ulcer begins as a papule that enlarges to a nodule and then breaks down into an ulcer. Two distinctive clinical and epidemiological diseases are recognised, the more common and widespread zoonotic rural disease with a moist acute form, caused by L. Major, with reservoir rodent hosts; and an urban, anthroponotic, dry, chronic form of leishmaniasis caused by leishmaniasis tropica, without a reservoir host, and now largely controlled. See: zoonotic cutaneous leishmaniasis, anthroponotic cutaneous leishmaniasis. Synonym: juccuya, Old World leishmaniasis, tropical sore. (05 Mar 2000) |
