Potential vectors of Leishmaniases in the Environmental Protection Area and Tinguá Federal Biological Reserve, Municipality of Nova Iguaçu, Rio de Janeiro, Brazil

Medical and Veterinary Entomology, EarlyView.
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 ...

Leptin enhances the efficacy of glucantime to modulate macrophage polarization toward the M1 phenotype in Leishmania tropica-infected macrophages

Parasites & Vectors
Background Macrophages are essential immune cells during Leishmania infection, as their polarization toward M1/M2 phenotypes determines disease outcome.

The use of K39 test in the diagnosis of visceral leishmaniasis [PDF]

, 2007
From time to time patients admitted with fever of unknown origin prove to be a diagnostic dilemma. While textbooks describe typical symptoms and signs, and also diagnostic tests, these are not always helpful.

Immunization with antigenic extracts of Leishmania associated with Montanide ISA 763 adjuvant induces partial protection in BALB/c mice against Leishmania (Leishmania) amazonensis infection [PDF]

, 2014
Background/Purpose: A proper adjuvant has a relevant role in vaccine formulations to generate an effective immune response. In this study, total Leishmania antigen (TLA) formulated with Montanide ISA 763 or R848 as adjuvants were evaluated as a first ...

Unravelling the biochemical aspects of the interaction between ticks and Leishmania using a tick cell line

Medical and Veterinary Entomology, EarlyView.
Leishmania infantum propagated in IDE8 tick cell line in vitro. L. infantum reduces tick cell viability and induces reactive oxygen species production. Lipidic profile of IDE8 tick cell line is altered during Leishmania infection. Abstract Leishmaniasis comprises a group of vector‐borne neglected tropical diseases caused by species of the obligatory ...

Monocyte Chemotactic Protein 1 in Plasma from Soluble Leishmania Antigen-Stimulated Whole Blood as a Potential Biomarker of the Cellular Immune Response to Leishmania infantum

Frontiers in Immunology, 2017
New biomarkers are needed to identify asymptomatic Leishmania infection as well as immunity following vaccination or treatment. With the aim of finding a robust biomarker to assess an effective cellular immune response, monocyte chemotactic protein 1 ...

Developing giant plasma membrane vesicles from Leishmania cells to investigate the role of membrane proteins in photodynamic inactivation

Photochemistry and Photobiology, EarlyView.
In this study, we developed giant plasma membrane vesicles (GPMVs) from Leishmania amazonensis promastigote membranes to investigate the role of protein‐embedded membranes in methylene blue (MB) photooxidation. Upon MB photoactivation in model lipid membranes (giant unilamellar vesicles, GUVs), a distinct photooxidation effect was observed, marked by ...

Incidence of Trypanosoma cruzi infection in two Guatemalan communities.

, 2004
The prevalence of human infection by Trypanosoma cruzi was assessed using an enzyme-linked immunosorbent assay (ELISA) in a serological survey in 1998 of 2 rural communities (SMH and PS) in Guatemala.

An Ocular Manifestation of a Systemic Disease With Encephalitozoon Pogonae in a Juvenile Central Bearded Dragon (Pogona vitticeps)

Veterinary Ophthalmology, EarlyView.
ABSTRACT Objective Encephalitozoon pogonae, a recently identified microsporidian species, has been associated with systemic infections in Central bearded dragons (Pogona vitticeps) manifesting as granulomatous inflammation and vasculitis. Despite the species similarity to Encephalitozoon cuniculi, which causes ocular, neurologic, and renal pathology in
