The retained capacity of Lutzomya longipalpis (Lutz & Neiva) to transmit Leishmania chagasi (Cunha & Chagas) after eight years (64 generations in a closed laboratory colony

open access: yesMemorias do Instituto Oswaldo Cruz, 1985
A closed Lutzomyia longipalpis colony, from Ceará has been used to transmit Leishmania chagasi isolated from a fox in Pará state. The last time this colony was successfully used in similar transmission experiments was eight years (64 generations) ago ...

Lutzomyia longipalpisPeritrophic Matrix: Formation, Structure, and Chemical Composition [PDF]

open access: yesJournal of Medical Entomology, 2005
Sandflies are vectors of several pathogens, constituting serious health problems. Lutzomyia longipalpis (Lutz & Neiva, 1912) is the main vector of Leishmania chagasi, agent of visceral leishmaniasis. They synthesize a thick bag-like structure that surrounds the bloodmeal, named peritrophic matrix (PM).

Neuroimmune Pain and Its Manipulation by Pathogens

open access: yesEvolutionary Applications, Volume 18, Issue 4, April 2025.
ABSTRACT Recent studies highlight extensive crosstalk that exists between sensory neurons responsible for pain and the immune system. Cutaneous pain neurons detect harmful microbes, recruit immune cells, and produce anticipatory immunity in nearby tissues. These complementary systems generally protect hosts from infections.

How Effective Are the Canine Visceral Leishmaniasis Vaccines Currently Being Tested in Dogs? A Systematic Review and Meta‐Analysis

open access: yesParasite Immunology, Volume 47, Issue 3, March 2025.
ABSTRACT Canine visceral leishmaniasis (CVL) is a zoonotic disease of great worldwide importance and can be prevented by vaccinating seronegative dogs. The objective of the present systematic review and meta‐analysis is to verify the efficacy rate of vaccines tested in dogs against CVL or L. infantum infection. We used PRISMA guidelines for this review
