This study was to describe the composition of sand fly fauna, detect potential vectors of Leishmania spp. in the Tinguá district, an ATL endemic, Rio de Janeiro, Brazil. Seven species of vectorial importance in the epidemiological cycle of leishmaniasis was observed: Nyssomyia intermedia, Migonemyia migonei, Pintomyia fischeri, Psychodopygus hirsutus ...

ABSTRACT Introduction Canine Leishmaniasis is a vector‐borne zoonotic disease caused by several species of protozoa of the genus Leishmania. In the state of Rio de Janeiro (RJ), Leishmania braziliensis is the most prevalent species causing tegumentary leishmaniasis (TL) and Leishmania infantum is the main causative agent of visceral leishmaniasis (VL).

Characterization of an extracellular serine protease ofLeishmania (Leishmania) amazonensis
A serine protease was purified 942-fold from culture supernatant ofL. amazonensispromastigotes using (NH4)2SO4precipitation followed by affinity chromatography on aprotinin-agarose and continuous elution electrophoresis by Prep Cell, yielding a total recovery of 61%.

Structural basis of secreted acid phosphatase polymerization in the Leishmania parasite
Abstract Enzymes that assemble into filaments typically transition between protomeric and polymeric states in response to cellular conditions. In contrast, the secreted acid phosphatase (SAP) of Leishmania, one of the most abundant extracellular glycoproteins produced by the parasite and regarded as a major virulence factor in the neglected tropical ...

In vitro evaluation of the anti-leishmanial activity and toxicity of PK11195
BACKGROUND Leishmaniasis, one of the most neglected diseases, is a serious public health problem in many countries, including Brazil. Currently available treatments require long-term use and have serious side effects, necessitating the development of new

Nano‐encapsulated Cinnamomum cassia essential oil (nano‐CC‐EO) showed in vitro antifungal activity against fluconazole‐resistant Nakaseomyces glabratus and Pichia kudriavzevii clinical isolates. Checkerboard assays revealed synergistic or additive interactions between nano‐CC‐EO and fluconazole in several isolates, without evidence of antagonism. These

Miltefosine induces programmed cell death in Leishmania amazonensis promastigotes
In the current study, we evaluated the mechanism of action of miltefosine, which is the first effective and safe oral treatment for visceral leishmaniasis, in Leishmania amazonensis promastigotes.

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

Active sesquiterpene lactones against Leishmania amazonensis and Leishmania braziliensis [PDF]
Seventeen sesquiterpene lactones (SLs) isolated from five species of the tribe Vernonieae were evaluated for their in vitro activity against promastigotes of Leishmania amazonensis and Leishmania braziliensis. Additionally, a quantitative structure activity relationship has been made, since all these natural compounds were found to have potent to mild ...
