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.

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.

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.

Peptides as a Therapeutic Alternative Against Leishmaniasis: A Scoping Review. [PDF]

Chem Biol Drug Des
This scoping review of 79 studies identified 231 antimicrobial peptides with anti‐Leishmania activity, including natural‐derived and synthetic peptides (inspired by natural sources or developed through rational design). Most were evaluated in vitro against promastigote and/or amastigote forms, with synthetic peptides showing a more promising effect ...

Thymus and Leishmania at the Crossroads: Autoimmunity and Cancer. [PDF]

Immunology
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 ...

Leishmania (infantum) chagasi in canine urinary sediment [PDF]

Revista Brasileira de Parasitologia Veterinária, 2015
Canine visceral leishmaniasis (CVL) is difficult to diagnosis, mainly due to the presence of asymptomatic animals, the diversity of clinical symptoms and the difficulty in obtaining diagnostic evidence of high sensitivity and specificity. The purpose of this study was to diagnose CVL in urinary sediment of 70 dogs of different breeds, sexes and ages ...
