Binding of Leishmania infantum Lipophosphoglycan to the Midgut Is Not Sufficient To Define Vector Competence in Lutzomyia longipalpis Sand Flies

mSphere, 2020
The major surface lipophosphoglycan (LPG) of Leishmania parasites is critical to vector competence in restrictive sand fly vectors in mediating Leishmania attachment to the midgut epithelium, considered essential to parasite survival and development ...

Fungal Biodiversity From the Atlantic Forest With Bioactive Metabolites Against Cutaneous Leishmaniasis

Chemistry &Biodiversity, EarlyView.
ABSTRACT Biodiversity offers a rich source of bioactive compounds for drug discovery. We isolated Aspergillus fumigatus from compost in the Atlantic Forest and found its extract active against Leishmania (Leishmania) amazonensis. Two crude extracts, I06 and I75, were selected for further study.

Study of in vitro biological activity of thiazoles on Leishmania (Leishmania) infantum

Journal of Global Antimicrobial Resistance, 2020
In the prospection of possible agents against neglected diseases, thiazole compounds are presented as promising candidates and are known to have activity against trypanosomatid parasites. Thus, this work aimed to evaluate the effects of thiazole compounds on Leishmania infantum, the aetiological agent of visceral leishmaniasis.Thiazole compounds (five ...

Serological and molecular survey of Leishmania parasites in apparently healthy dogs in the West Bank, Palestine

Parasites & Vectors, 2012
Background Canine visceral leishmaniasis (CVL) is caused by Leishmania infantum in all Mediterranean countries. The Leishmania parasite is transmitted by the bite of a corresponding sand fly vector and primarily maintained in nature by wild and domestic ...
