Rift valley fever: diagnostic challenges and investment needs for vaccine development

BMJ Global Health, 2020
Rift valley fever virus (RVFV) is a causative agent of a viral zoonosis that constitutes a major clinical burden in wild and domestic ruminants. The virus causes major outbreaks in livestock (sheep, goats, cattle and camels) and can be transmitted to ...

Molecular Detection and Genetic Diversity of Bat‐Associated Bartonella spp. in Bat Ectoparasites Collected From Ratchaburi Province, Thailand

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
Bat ectoparasites collected from four insectivorous bat species were identified through mitochondrial gene analysis. This study provides the first evidence of bat‐associated Bartonella species in ectoparasites, including bat flies (Phthiridium sp., Raymondia sp.

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,

Bee products as alternatives in the treatment of viral infections

Journal of the Science of Food and Agriculture, Volume 106, Issue 1, Page 33-54, 15 January 2026.
Abstract Medicines used in the treatment of viral infections usually reduce symptoms. There is a need to develop drugs that inhibit the viruses and do not merely relieve the symptoms. Natural bee products possess many pharmacological properties and are widely used in folk medicine. There are many studies on the antibacterial effects of bee products but

Human immune cell engraftment does not alter development of severe acute Rift Valley fever in mice. [PDF]

PLoS ONE, 2018
Rift Valley fever (RVF) in humans is usually mild, but, in a subset of cases, can progress to severe hepatic and neurological disease. Rodent models of RVF generally develop acute severe clinical disease.

Amphibian Strategies Against Attacks by Flies: Host‐Specificity and Threats

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Species interactions between Diptera flies and amphibians play a significant role in tropical ecosystems, but their ecology and evolution remain understudied. This review explores the costs flies impose on amphibians, such as pathogen transmission and disruption of communication systems, and highlights the evolutionary strategies employed by both ...
