Extensive variation and strain-specificity in dengue virus susceptibility among African < i > Aedes aegypti < /i > populations
by St éphanie Dabo, Annabelle Henrion-Lacritick, Alicia Lecuyer, Davy Jiolle, Christophe Paupy, Diego Ayala, Silvânia da Veiga Leal, Athanase Badolo, Anubis Vega-Rúa, Massamba Sylla, Jewelna Akorli, Sampson Otoo, Joel Lutomiah, Rosemary Sang, John-Paul Mutebi, Maria-Carla Saleh, Noah H. Rose, Carolyn S . McBride, Louis Lambrechts African populations of the mosquitoAedes aegypti are usually considered less susceptible to infection by human-pathogenic flaviviruses than globally invasive populations found outside Africa. Although this contrast has been well documented for Zika virus (ZIKV), it is unclear to what extent it...

Urinary dengue NS1 detection on Au-decorated ZnO nanowire platform
Biosens Bioelectron. 2024 Mar 13;254:116218. doi: 10.1016/j.bios.2024.116218. Online ahead of print.ABSTRACTBiodetection for non-invasive diagnostics of fluids, especially urine, remains a challenge to scientists due to low target concentrations. And biological complexes of the detection target may contain contaminants that also interfere with any assay. Dengue non-structural 1 protein (Dengue NS1) is an important biomarker for dengue hemorrhagic fever and dengue shock syndrome. Here, we developed an Au-decorated nanowire platform and applied it with a sandwich fluorophore-linked immunosorbent well plate assay (FLISA) to d...

E-Protein Protonation Titration-Induced Single-Particle Chemical Force Spectroscopy for Microscopic Understanding and pI Estimation of Infectious DENV
J Phys Chem B. 2024 Mar 21. doi: 10.1021/acs.jpcb.4c00057. Online ahead of print.ABSTRACTThe ionization state of amino acids on the outer surface of a virus regulates its physicochemical properties toward the sorbent surface. Serologically different strains of the dengue virus (DENV) show different extents of infectivity depending upon their interactions with a receptor on the host cell. To understand the structural dependence of E-protein protonation over its sequence dependence, we have followed E-protein titration kinetics both experimentally and theoretically for two differentially infected dengue serotypes, namely, DE...

Scoring systems for prediction of malaria and dengue fever in non-endemic areas among travellers arriving from tropical and subtropical areas
Conclusion The presented scoring systems provide novel tools for structured assessment of patients with tropical fever in a non-endemic area and highlight clinical signs associated with a potential severe aetiology to direct the need for microbial investigation. (Source: Emergency Medicine Journal)
