Real-time PCR to differentiate among Leishmania (Viannia) subgenus, Leishmania (Leishmania) infantum and Leishmania (Leishmania) amazonensis: Application on Brazilian clinical samples

Acta Tropica, 2020
Leishmaniasis is a complex disease caused by Leishmania species belonging to subgenera Leishmania and Viannia. In South America, L. (L.) infantum is considered the most important causative agent of visceral leishmaniasis, while L. (L.) amazonensis and Viannia subgenus species are responsible for the different cutaneous or mucocutaneous forms.

Loop-mediated isothermal amplification (LAMP): An advanced molecular point-of-care technique for the detection of Leishmania infection

PLoS Neglected Tropical Diseases, 2019
Leishmaniasis, caused by protozoan parasites of the Leishmania genus, represents an important health problem in many regions of the world. Lack of effective point-of-care (POC) diagnostic tests applicable in resources-limited endemic areas is a critical ...

Unveiling the Leishmanicidal Mechanism of 4-Nerolidylcatechol Isolated From Piper peltatum Against Leishmania infantum. [PDF]

Chem Biodivers
ABSTRACT The present study assessed the leishmanicidal activity of 4‐nerolidylcatechol (4‐NC) (1) isolated from Piper peltatum leaves against promastigotes and amastigotes of Leishmania amazonensis, L. braziliensis, and L. infantum. The plant was fractionated, leading to the isolation and chemical identification of 4‐NC (1). Biochemical techniques were

Sphingolipid Degradation in Leishmania (Leishmania) amazonensis

PLoS Neglected Tropical Diseases, 2012
Human leishmaniasis is caused by more than 20 Leishmania species and has a wide range of symptoms. Our recent studies have demonstrated the essential role of sphingolipid degradation in the virulence of Leishmania (Leishmania) major, a species responsible for localized cutaneous leishmaniasis in the Old World.
