Advancing Insights Into Visceral Leishmaniasis: Challenges, Innovations, and Future Directions in Global Disease Management

Journal of Parasitology Research, Volume 2025, Issue 1, 2025.
Background Visceral leishmaniasis (VL), also known as kala‐azar, is a life‐threatening neglected tropical disease primarily caused by Leishmania donovani and transmitted by infected sandflies. Despite notable advancements in public health, VL continues to pose significant challenges, especially in South Asia, East Africa, and South America.

Antibody response to sand fly saliva is a marker of transmission intensity but not disease progression in dogs naturally infected with Leishmania infantum [PDF]

, 2018
BACKGROUND: Antibody responses to sand fly saliva have been suggested to be a useful marker of exposure to sand fly bites and Leishmania infection and a potential tool to monitor the effectiveness of entomological interventions.

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

Journal 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.

Leishmaniasis: new approaches to disease control. [PDF]

, 2003
The leishmaniases afflict the world's poorest populations. Among the two million new cases each year in the 88 countries where the disease is endemic (fig 1), it is estimated that 80% earn less than $2 a day.

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

Insect 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.
