Heterogeneities in leishmania infantum infection : using skin parasite burdens to identify highly infectious dogs [PDF]

, 2013
Background: The relationships between heterogeneities in host infection and infectiousness (transmission to arthropod vectors) can provide important insights for disease management.

FIRST REPORT OF CUTANEOUS LEISHMANIASIS CAUSED BY Leishmania (Leishmania) infantum chagasi IN AN URBAN AREA OF RIO DE JANEIRO, BRAZIL

Revista do Instituto de Medicina Tropical de São Paulo, 2015
SUMMARY American tegumentary leishmaniasis (ATL) is an infectious disease caused by protozoa of the genus Leishmania, and transmitted by sandflies. In the state of Rio de Janeiro, almost all of the cases of American tegumentary leishmaniasis (ATL) are ...

Leishmania donovani is the only cause of visceral leishmaniasis in East Africa; previous descriptions of L. infantum and "L. archibaldi" from this region are a consequence of convergent evolution in the isoenzyme data [PDF]

, 2004
Isoenzyme-based studies have identified 3 taxa/species/'phylogenetic complexes' as agents of visceral leishmaniasis in Sudan: L. donovani, L. infantum and "L. archibaldi". However, these observations remain controversial.

Inducible Resistance to Oxidant Stress in the Protozoan Leishmania chagasi [PDF]

Journal of Biological Chemistry, 2000
Leishmania sp. protozoa are introduced into a mammalian skin by a sandfly vector, whereupon they encounter increased temperature and toxic oxidants generated during phagocytosis. We studied the effects of 37 degrees C "heat shock" or sublethal menadione, which generates superoxide and hydrogen peroxide, on Leishmania chagasi virulence.

Biology of visceral leishmaniasis vectors in San Andres de Sotavento focus (Cordoba Colombia). [PDF]

Throughout its range of South and Central America, visceral leishmaniasis due to Leishmania chagasi is transmitted by Lutzomyia longipalpis. Recently, a new vector, Lutzomyia evansi, has been discovered transmitting the parasite in ...

Thymus and Leishmania at the Crossroads: Autoimmunity and Cancer

Immunology, Volume 178, Issue 3, Page 377-386, July 2026.
Conceptual ‘Crossroads Model’ linking Leishmania, thymic infection and immune dysregulation: an integrative model is proposed in which Leishmania infection disrupts thymic architecture and stromal–thymocyte interactions. These alterations converge to promote defective tolerance, increased autoimmune risk and a microenvironment permissive to malignant ...

Anti-leishmania antibodies in cerebrospinal fluid from dogs with visceral leishmaniasis

Brazilian Journal of Medical and Biological Research, 2003
Visceral leishmaniasis in Brazil is caused by Leishmania (Leishmania) chagasi and the dog is its most important reservoir. The clinical features in dogs include loss of weight, lymphadenopathy, renal failure, skin lesions, fever, hypergammaglobulinemia ...

Is it time to revise the nomenclature of Leishmania?

, 2010
Leishmania is notable for a large number of described species. Molecular phylogenies of Leishmania have increasingly suggested that the number of species could be too large.

Evolutionary and geographical history of the Leishmania donovani complex with a revision of current taxonomy. [PDF]

, 2007
Leishmaniasis is a geographically widespread severe disease, with an increasing incidence of two million cases per year and 350 million people from 88 countries at risk. The causative agents are species of Leishmania, a protozoan flagellate.
