Assessment of Leishmania exposure in blood donors from a non‐endemic urban area: A study in São Paulo

Vox Sanguinis, EarlyView.
Abstract Background and Objectives According to the World Health Organization, more than 1 billion people are at risk of leishmaniasis in over 89 countries. Environmental changes such as deforestation, urban expansion and climate change facilitate the spread of sand fly vectors and reservoirs, increasing disease transmission.

Phlebotomine sandfly (Diptera: Psychodidae) diversity and their Leishmania DNA in a hot spot of American Cutaneous Leishmaniasis human cases along the Brazilian border with Peru and Bolivia

Memórias do Instituto Oswaldo Cruz, 2016
In this study, we identified the phlebotomine sandfly vectors involved in the transmission of American Cutaneous Leishmaniasis (ACL) in Assis Brasil, Acre, Brazil, which is located on the Brazil-Peru-Bolivia frontier.

Toward Dual‐Function Nanoparticle Platforms for Arboviral Diagnostics and Vaccines: Advances, Challenges, and Future Prospects

Nano Select, Volume 7, Issue 2, February 2026.
This review explores nanoparticle (NP)‐based biosensors and nanovaccine platforms for arboviral infections, highlighting their design, performance, and translational potential. By comparing case studies across viruses, it identifies gold‐standard nanomaterials such as gold NPs (AuNPs), zinc oxide NPs (ZnONPs), molybdenum disulfide (MoS2) nanocomposites,

Properties and Limitations of eDNA Substrates for Terrestrial Animal Monitoring

Molecular Ecology Resources, Volume 26, Issue 2, February 2026.
ABSTRACT Environmental DNA (eDNA) constitutes a valuable tool for monitoring terrestrial animal diversity, but outcomes are affected by multiple factors. Among these factors, the choice of sampling substrate and method is especially important and must be aligned with research objectives.

Preliminary laboratory and field trials of a heated pheromone trap for the sandfly lutzomyia logipalpis (Diptera: Psychodidae)

Memorias do Instituto Oswaldo Cruz, 1990
A heated pheromone trap for the sandfly Lutzomyia longipalpis was tested in the laboratory using filter paper or plastic vial dispensers. Male pheromone extracted from 8 male tergal glands and absorbed on to filter paper dispensers attracted 82/120 (68.3%

The sandfly Lutzomyia longipalpis LL5 embryonic cell line has active Toll and Imd pathways and shows immune responses to bacteria, yeast and Leishmania

Parasites & Vectors, 2016
BackgroundLutzomyia longipalpis is the main vector of visceral leishmaniasis in Latin America. Sandfly immune responses are poorly understood. In previous work we showed that these vector insects respond to bacterial infections by modulating a defensin ...

Molecular Screening of Black Flies (Diptera: Simuliidae) for Vector‐Borne Zoonotic Pathogens, South Moravia, Czech Republic

Zoonoses and Public Health, Volume 73, Issue 1, Page 95-106, February 2026.
ABSTRACT Introduction Black flies (Simuliidae) are globally distributed blood‐feeding arthropods and vectors of viral, bacterial, and parasitic pathogens to many animal species, including humans. We investigated the occurrence of selected vector‐borne pathogens in black flies in South Moravia, Czech Republic, and evaluated their possible role in the ...

How to increase the population of a Phlebotomus perniciosus (Diptera: Psychodidae) colony: a new method

Memorias do Instituto Oswaldo Cruz, 2011
The sandfly Phlebotomus perniciosus is the most widespread vector of Leishmania infantum in Spain. Laboratory colonisation represents the most feasible source of information on the biology of these insects, but in conducting any study, the density of ...

Sandfly fauna (Diptera: Psychodidae) in an urban area, Central-West of Brazil

Revista do Instituto de Medicina Tropical de São Paulo, 2017
Biological and ecological relations among vectors and their pathogens are important to understand the epidemiology of vector-borne diseases. Camapuã is an endemic area for visceral and tegumentary leishmaniasis.
