Chicken blood provides a suitable meal for the sand fly Lutzomyia longipalpis and does not inhibit Leishmania development in the gut [PDF]

, 2010
Background The aim of this study was to address the role of chickens as bloodmeal sources for female Lutzomyia longipalpis and to test whether chicken blood is harmful to Leishmania parasite development within the sand flies.

Cutaneous Leishmaniasis Mimicking a Nasal Tumor: A Case Report. [PDF]

Case Rep Infect Dis
Leishmaniasis is a disease caused by Leishmania protozoa that is transmitted to the patient by sand flies. Depending on the Leishmania species, the disease can present with cutaneous, mucosal, or multiorgan involvement. Cutaneous leishmaniasis can present with diverse clinical manifestations mimicking other diseases.

Leishmania chitinase facilitates colonization of sand fly vectors and enhances transmission to mice [PDF]

, 2008
Chitinases of trypanosomatid parasites have been proposed to fulfil various roles in their blood-feeding arthropod vectors but so far none have been directly tested using a molecular approach.

T helper1/T helper2 cells and resistance/susceptibility to Leishmania infection : is this paradigm still relevant? [PDF]

, 2012
Work in large part on Leishmania major in the 1980s identified two distinct apparently counter-regulatory CD4 T cell populations, T helper (h)1 and Th2, that controlled resistance/susceptibility to infection respectively.

MAP kinase phosphatase-2 plays a critical role in response to infection by Leishmania mexicana [PDF]

, 2010
In this study we generated a novel dual specific phosphatase 4 (DUSP4) deletion mouse using a targeted deletion strategy in order to examine the role of MAP kinase phosphatase-2 (MKP-2) in immune responses.

Comparative study of the ability of Leishmania mexicana promastigotes and amastigotes to alter macrophage signalling and functions [PDF]

, 2010
Leishmania alternates between two morphologically different stages: promastigotes and amastigotes. While the majority of reports focused on how the promastigote form can alter macrophage signalling and function, fewer reports investigated signalling ...
