Factors Associated With the Emergence and Spread of Visceral Leishmaniasis in the State of São Paulo, Brazil

Zoonoses and Public Health, Volume 73, Issue 4, Page 348-357, June 2026.
ABSTRACT Introduction Visceral leishmaniasis (VL), once considered a rural disease in Brazil, has progressively urbanised, particularly in the state of São Paulo (SSP), where the first urban cases emerged after the detection of the vector Lutzomyia longipalpis in 1997.

Identification and mapping of potential and highly likely vectors for selected vector‐borne diseases in the EU and neighbouring countries

EFSA Journal, Volume 24, Issue 5, May 2026.
Abstract This report addresses Term of Reference 1.2 by providing a comprehensive knowledge‐mapping of arthropod vector species competent to transmit selected vector‐borne diseases (VBDs) including VBDs listed under Regulation (EU) 2016/429 and Regulation (EU) 2020/687, as well as additional non‐listed pathogens with potential epidemiological relevance.

Carbohydrate digestion in Lutzomyia longipalpis’ larvae (Diptera – Psychodidae)

Journal of Insect Physiology, 2012
Lutzomyia longipalpis is the principal species of phlebotomine incriminated as vector of Leishmania infantum, the etiological agent of visceral leishmaniasis in the Americas. Despite its importance as vector, almost nothing related to the larval biology, especially about its digestive system has been published. The objective of the present study was to

The Regulatory Effect of Histone Deacetylase (HDAC) 1 and 2 on iNOS, IL‐6, TNF‐α and IL‐10 Expression in Canine Macrophages Infected With Leishmania infantum

Parasite Immunology, Volume 48, Issue 4, April 2026.
ABSTRACT Zoonotic visceral leishmaniasis is caused by Leishmania (Leishmania) infantum. Dogs are considered the most critical urban reservoirs of L. (L.) infantum due to their high infection rate and direct transmission to humans. The parasite has developed mechanisms to evade the host's defence system by inhibiting macrophage activation, thereby ...

The Sensory Ecology of Tsetse Flies: Neuroscience Perspectives on a Disease Vector

European Journal of Neuroscience, Volume 63, Issue 2, January 2026.
Tsetse flies (Glossina sp.) are important disease vectors that feed on vertebrate blood. Host‐seeking depends on a combination of sensory systems, from long‐range senses like olfaction and vision, to shorter‐range senses such as audition, mechanosensation, thermosensation and taste.
