Canine Leishmaniasis in Rio de Janeiro, Brazil (2000–2015): Taxonomic Characterisation of Etiological Agents and Geospatial Case Analysis

Zoonoses and Public Health, Volume 73, Issue 4, Page 314-325, June 2026.
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).

Comparative two-dimensional gel electrophoresis maps for promastigotes of Leishmania amazonensis and Leishmania major

Brazilian Journal of Infectious Diseases
The outcome of Leishmania infections is determined by both the parasite species and the host genetic makeup. While much has been learned regarding immune responses to this parasite, our knowledge on parasite-derived factors is limited.

Structural basis of secreted acid phosphatase polymerization in the Leishmania parasite

Protein Science, Volume 35, Issue 5, May 2026.
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 ...

Nano‐Encapsulated Cinnamomum cassia Essential Oil in Combination With Fluconazole Exhibits Synergistic Activity Against Fluconazole‐Resistant Nakaseomyces glabratus and Pichia kudriavzevii

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
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

Cell structure and cytokinesis alterations in multidrug-resistant Leishmania (Leishmania) amazonensis [PDF]

Parasitology Research, 2004
Multidrug-resistant Leishmania (Leishmania) amazonensis may be obtained by in vitro selection with vinblastine. In order to determine whether this phenotype is linked to structural alterations, we analyzed the cell architecture by electron microscopy. The vinblastine resistant CL2 clone of L.

Peptides as a Therapeutic Alternative Against Leishmaniasis: A Scoping Review

Chemical Biology &Drug Design, Volume 107, Issue 5, May 2026.
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 ...
