Performance of Extracellular Vesicles From Leishmania (Leishmania) infantum for Serological Diagnosis of Human and Canine Visceral Leishmaniasis

open access: yesJournal of Parasitology Research, Volume 2025, Issue 1, 2025.
Visceral leishmaniasis (VL) is a zoonotic disease in which dogs are the main reservoirs. Until now, the serological tests do not present satisfactory sensitivity for diagnosis of these hosts. One of the functions of extracellular vesicles (EVs) is related to immunological host response.

The RNA interference response to alphanodavirus replication in Phlebotomus papatasi sand fly cells

open access: yesInsect Molecular Biology, Volume 33, Issue 6, Page 687-696, December 2024.
Both the siRNA and piRNA pathways are transcriptionally active in Phlebotomus papatasi PP9ad cells. Assembly of small RNA sequencing identifies an adventitious nodavirus (American nodavirus [ANV]) in PP9ad cells. ANV is actively replicating in PP9ad cells and is targeted by the exo‐siRNA pathway but not the piRNA pathway.

The Transcriptome of Lutzomyia longipalpis (Diptera: Psychodidae) Male Reproductive Organs

open access: yesPLoS ONE, 2012
It has been suggested that genes involved in the reproductive biology of insect disease vectors are potential targets for future alternative methods of control. Little is known about the molecular biology of reproduction in phlebotomine sand flies and there is no information available concerning genes that are expressed in male reproductive organs of ...

Ecological determinants of leishmaniasis vector, Lutzomyia spp.: A scoping review

open access: yesMedical and Veterinary Entomology, Volume 38, Issue 4, Page 393-406, December 2024.
Lutzomyia spp. survival is impacted by climatic, habitat and geodemographic factors. Lutzomyia spp. have demonstrated a wide range of temperature tolerance, ranging from 11 to 30°C. There is limited research on this topic, posing a significant challenge for future studies. Abstract Leishmania spp. are zoonotic parasites transmitted by phlebotomine sand
