Immucillins Impair Leishmania (L.) infantum chagasi and Leishmania (L.) amazonensis Multiplication In Vitro [PDF]

PLoS ONE, 2015
Chemotherapy against visceral leishmaniasis is associated with high toxicity and drug resistance. Leishmania parasites are purine auxotrophs that obtain their purines from exogenous sources.

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,

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 ...

Characterization of Leishmania (L.) infantum chagasi in visceral leishmaniasis associated with hiv co-infection in Northeastern Brazil [PDF]

Revista do Instituto de Medicina Tropical de São Paulo, 2017
Visceral leishmaniasis, associated with HIV/AIDS coinfection, is becoming a more aggressive disease, complicating an accurate prognosis. A 21-year-old HIV-positive female presenting with clinical features of visceral leishmaniasis was enrolled in this ...

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 ...

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.

A comprehensive phenotypic and genotypic taxonomic review of Leishmania (Leishmania) poncei n. sp. (Kinetoplastea: Trypanosomatidae): a novel agent of cutaneous (non-ulcerated) and visceral leishmaniasis in Honduras, Central America [PDF]

Tropical Diseases, Travel Medicine and Vaccines
Non-ulcerated cutaneous leishmaniasis (NUCL) is an atypical clinical form of leishmaniasis first described, in 1988, by Ponce and collaborators, in Honduras, Central America, characterized by isolated or disseminated closed skin lesions appearing as ...
