Analysis of climatic and seasonal effects on the oviposition activity of Aedes spp. females in municipalities of Paraná, Brazil

Austral Entomology, Volume 65, Issue 2, May 2026.
Abstract Climate and environmental changes driven by global economic activities directly affect the physiology of insect vectors, such as Aedes spp., accelerating their development, increasing the number of generations per season and increasing the risk of transmission of aetiological agents. This study aimed to analyse how local climatic variables and

Differential unfolded protein response during Chikungunya and Sindbis virus infection: CHIKV nsP4 suppresses eIF2α phosphorylation [PDF]

Virology Journal, 2013
Abstract Chikungunya (CHIKV) and Sindbis (SINV) are arboviruses belonging to the alphavirus genus within the Togaviridae family. They cause frequent epidemics of febrile illness and long-term arthralgic sequelae that affect millions of people each year.

Synthesis and Anti-Chikungunya Virus (CHIKV) Activity of Novel 1,4-Naphthoquinone Sulfonamide and Sulfonate Ester Derivatives

Journal of the Brazilian Chemical Society, 2022
Chikungunya virus (CHIKV) is a re-emerging disease caused by an alphavirus of the Togaviridae family. Since its first description in 1952, the disease has spread worldwide, affecting populations in both tropical and temperate countries. To date, there is no licensed vaccine or specific pharmacological treatment.

Using blood donor surveillance and clinical case data to shape our understanding of Babesia epidemiology in Manitoba, Canada

Transfusion, Volume 66, Issue 5, Page 916-922, May 2026.
Abstract Background Babesia is a parasite transmitted by the Ixodes tick and has the potential to be transfusion transmitted. Climate change and changing Ixodes tick distributions in Canada raised questions about the impact of Babesia on the blood supply.

Alphaviral Capsid Proteins Inhibit Stress Granule Assembly via Competitive RNA Binding With G3BP1

Advanced Science, Volume 13, Issue 20, 9 April 2026.
Stress granules exert antiviral functions. This study illustrates a conserved function of alphaviral capsid proteins in modulating stress granules. Oligomerization mediated by a helical motif coupled with a positively charged intrinsically disordered region (IDR) directly competes with G3BP1 for RNA binding, thereby disrupting G3BP1‐RNA liquid–liquid ...

Chikungunya virus and Aedes mosquitoes: saliva is infectious as soon as two days after oral infection.: Salivation and CHIKV

, 2009
International audienceBACKGROUND: Aedes aegypti and Aedes albopictus are potential vectors of chikungunya virus (CHIKV). The recent CHIKV outbreaks were caused by a new variant characterized by a mutation in the E1 glycoprotein gene (E1-226V) which has ...

Development of a Reverse Transcription Recombinase Polymerase Amplification CRISPR/Cas12a Assay for Visual and Highly Specific Identification of Zika Virus

Journal of Medical Virology, Volume 98, Issue 4, April 2026.
ABSTRACT Zika virus (ZIKV), a single‐stranded positive‐sense RNA virus of the Flaviviridae family (Flavivirus genus), causes acute febrile illness and severe congenital anomalies. Serological cross‐reactivity with Dengue virus (DENV) and Chikungunya virus (CHIKV) complicates diagnosis, underscoring the urgency of developing specific point‐of‐care tests
