IL-1beta, IL-6, and RANTES as biomarkers of Chikungunya severity.

PLoS ONE, 2009
BackgroundLittle is known about the immunopathogenesis of Chikungunya virus. Circulating levels of immune mediators and growth factors were analyzed from patients infected during the first Singaporean Chikungunya fever outbreak in early 2008 to establish

Maltase 1 regulates DENV2 infection and life history in Aedes aegypti

Insect Science, EarlyView.
Our study employed CRISPR/Cas9 to generate a MAL1 knockout strain of Aedes aegypti, demonstrating that the absence of MAL1 significantly suppresses DENV2 replication in the midgut and impairs viral transmission. The mutation also altered life‐history (hatching/pupation/emerging rates and sex‐specific survival), identifying MAL1 as a novel target for ...

Preimaginal development of Aedes aegypti L. (Diptera: Culicidae) in brackish water gives rise to adult mosquitoes with thicker cuticles and greater insecticide resistance

Medical and Veterinary Entomology, EarlyView.
The principal arboviral vector Aedes aegypti can develop in coastal brackish water field habitats (0.5–15 g/L salt) with larvae possessing thicker cuticles and greater resistance to the larvicide Temephos. Females emerging from brackish water‐developing preimaginal stages are now shown to have thicker and remodelled leg and abdominal cuticles and ...

A blood safety perspective on emerging arboviral infections in the United Kingdom

Transfusion Medicine, EarlyView.
Abstract A core focus of the blood services is to maintain the blood supply whilst simultaneously being vigilant for potential threats to blood safety. At present, West Nile virus (WNV), Usutu virus (USUV), Dengue virus (DENV) and Tick‐borne encephalitis virus (TBEV) are considered primary arboviral threats to blood safety in the UK and Northern Europe.

Blood donor West Nile virus screening identifies three autochthonous Usutu virus infections in Spain

Transfusion, EarlyView.
Abstract Background Considering the increase of West Nile virus (WNV) circulation in Europe, blood banks perform WNV Nucleic Acid Test testing to ensure transfusion safety during the WNV transmission season. Usutu virus (USUV), an arbovirus related to WNV, has relevant molecular and serological cross‐reactivity with WNV. Study Design and Methods During

Comparative Study of Chikungunya Only and Chikungunya-Scrub Typhus Coinfection in Children: Findings from a Hospital-Based Observational Study from Central Nepal

International Journal of Pediatrics, 2021
Objectives. Chikungunya and scrub typhus infection are important causes of undifferentiated fever in tropical zones. The clinical manifestations in both conditions are nonspecific and often overlap. This study compares the clinical manifestations and the

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
