Guns, germs and dogs: On the origin of Leishmania chagasi

Infection, Genetics and Evolution, 2011
The evolutionary history of Leishmania chagasi, the aetiological agent of visceral leishmaniasis in South America has been widely debated. This study addresses the problem of the origin of L. chagasi, its timing and demography with fast evolving genetic markers, a suite of Bayesian clustering algorithms and coalescent modelling.

Recombinant LPG3 Protein From Leishmania chagasi as an Antigen for the Diagnosis of Canine Visceral Leishmaniasis. [PDF]

Trop Med Int Health
ABSTRACT Visceral leishmaniasis (VL) is a human neglected tropical disease in which dogs participate as reservoirs of the etiological agent Leishmania chagasi. The identification of infected dogs is important to the control of VL, and recombinant proteins are strong antigen candidates for canine visceral leishmaniasis (CVL) serodiagnosis. In this work,

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.

Brain Involvement in Leishmaniasis. [PDF]

Cell Biochem Funct
ABSTRACT Leishmaniasis is a neglected tropical disease caused by infection with the protozoan parasite Leishmania and it is a significant global health problem. The disease has a wide clinical spectrum, from tegumentary leishmaniasis (TL) that encompasses cutaneous (CL), mucosal (ML) and cutaneous‐diffuse (CDL) forms, to the potentially fatal systemic ...

Assessment of Leishmania exposure in blood donors from a non-endemic urban area: A study in São Paulo. [PDF]

Vox Sang
Abstract Background and Objectives According to the World Health Organization, more than 1 billion people are at risk of leishmaniasis in over 89 countries. Environmental changes such as deforestation, urban expansion and climate change facilitate the spread of sand fly vectors and reservoirs, increasing disease transmission.

Investigation of the bacterial communities associated with females of Lutzomyia sand fly species from South America [PDF]

, 2012
Phlebotomine sand flies are vectors of Leishmania that are acquired by the female sand fly during blood feeding on an infected mammal. Leishmania parasites develop exclusively in the gut lumen during their residence in the insect before transmission to a

Inhibition of trypsin expression in Lutzomyia longipalpis using RNAi enhances the survival of Leishmania [PDF]

, 2009
Background Leishmania parasites must overcome several barriers to achieve transmission by their sand fly vectors. One of the earliest threats is exposure to enzymes during blood meal digestion.

Investigating the role of the Leishmania (Leishmania) major HASP and SHERP genes during metacyclogenesis in the sand fly vectors, Phlebotomus (Phlebotomus) papatasi and Ph. (Ph.) duboscqi [PDF]

, 2013
Leishmania parasites are the causative agents of a diverse spectrum of infectious diseases termed the leishmaniases. These digenetic parasites exist as intracellular, aflagellate amastigotes in a mammalian host and as extracellular flagellated ...

Leishmaniasis Transmission Risk at the Forest-Peridomestic Interface in an Area of Southern Sinaloa, Mexico: Entomological, Molecular, and Climatic Evidence. [PDF]

J Parasitol Res
Leishmaniasis, caused by Leishmania spp. and transmitted by phlebotomine sand flies, affects almost 1,000,000 people annually across more than 90 countries. In Mexico, growing evidence of locally acquired transmission in northwestern states makes ecoepidemiological work increasingly urgent.
