| leishmania tropica | A parasitic haemoflagellate of the subgenus leishmania leishmania that infects man and rodents. This taxonomic complex includes species which cause a disease called oriental sore which is a form of cutaneous leishmaniasis (leishmaniasis, cutaneous) of the old world. (12 Dec 1998) |
|---|---|
| Leishmania tropica major | A parasitic haemoflagellate of the subgenus leishmania leishmania that infects man and animals and causes cutaneous leishmaniasis (leishmaniasis, cutaneous) of the old world. Transmission is by phlebotomus sandflies. (12 Dec 1998) |
| Leishmania tropica mexicana | A parasitic haemoflagellate of the subgenus leishmania leishmania that infects man and animals including rodents. The leishmania mexicana complex causes both cutaneous (leishmaniasis, cutaneous) and diffuse cutaneous leishmaniasis (leishmaniasis, diffuse cutaneous) and includes the subspecies amazonensis, garnhami, mexicana, pifanoi, and venezuelensis. L. M. Mexicana causes chiclero ulcer, a form of cutaneous leishmaniasis (leishmaniasis, cutaneous) in the new world. The sandfly, lutzomyia, appears to be the vector. (12 Dec 1998) |
| leishmaniasis | <infectious disease> Caused by protozoan parasites of the genus Leishmania. The parasite lives intracellularly in macrophages. Various forms of the disease are known, depending upon the species of parasite: in particular visceral leishmaniasis (kala azar) and muco cutaneous leishmaniasis. (18 Nov 1997) |
| leishmaniasis americana | 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) |
| leishmaniasis recidivans | A partially healing leishmanial lesion caused by Leishmania tropica and characterised by an extreme form of cellular immune response, intense granuloma production, fibrinoid necrosis without caseation, and frequent development of satellite lesions that continue the production of granulomatous tissue without healing, sometimes over a period of many years; organisms are difficult to demonstrate but can be cultured. Synonym: lupoid leishmaniasis. (05 Mar 2000) |
| 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) |
| leishmanin test | A delayed hypersensitivity test for cutaneous leishmaniasis; a positive test when granulomatous induration exceeds 5 min after 2-3 days at the intradermal injection site of a suspension of leishmanias in phenol. Synonym: Montenegro test. Origin: Leishmania + suffix -in, component, derivative (05 Mar 2000) |
| leishmaniosis | <infectious disease> Caused by protozoan parasites of the genus Leishmania. The parasite lives intracellularly in macrophages. Various forms of the disease are known, depending upon the species of parasite: in particular visceral leishmaniasis (kala azar) and muco cutaneous leishmaniasis. (18 Nov 1997) |
| leishmanoid | A condition resembling leishmaniasis. (05 Mar 2000) |

| leishmanin t. |
intradermal injection of leishmanin (leishmania promastigote antigens); a positive reaction consists of a palpable nodule developing in 48 to 72 hours and indicates delayed hypersensitivity, but not necessarily immunity, to leishmania organisms. The test is not species-specific. It becomes positive early in the course of cutaneous or mucocutaneous leishmaniasis, particularly the New World forms, except in diffuse cutaneous leishmaniasis; it becomes positive only after recovery from visceral leishmaniasis. Called also Montenegro t.
