Influence of blood meal on the responsiveness of olfactory receptor neurons in antennal sensilla trichodea of the yellow fever mosquito, Aedes aegypti [PDF]

, 2010
In female Aedes aegypti L. mosquitoes, a blood meal induces physiological and behavioral changes. Previous studies have shown that olfactory receptor neurons (ORNs) housed in grooved peg sensilla on the antennae of Ae.

RNAi Regulator C3PO Promotes Arbovirus Infection in Insect Vectors

Advanced Science, EarlyView.
RNA interference (RNAi) is vital for eukaryotes to defend against virus infection. The C3PO complex takes part in RNAi but its role in regulating viral infection remains unclear. This work finds that insect C3PO facilitates arbovirus replication by degrading precursors of miRNAs, especially miR‐971‐3p.

Emerging and reemerging arboviruses: a new threat in Eastern Peru [PDF]

, 2017
Background: Arboviral diseases are one of the most common causes of acute febrile illness (AFI) and a significant health problem in South America. In Peru, laboratory etiologic identification of these infections occurs in less than 50% of cases, leading ...

Machine Learning‐Assisted Infectious Disease Detection in Low‐Income Areas: Toward Rapid Triage of Dengue and Zika Virus Using Open‐Source Hardware

Advanced Intelligent Discovery, EarlyView.
This study introduces an affordable machine learning platform for simultaneous dengue and zika detection using fluorine‐doped tin oxide thin films modified with gold nanoparticles and DNA aptamers. Designed for low‐cost, hardware‐limited devices (< $25), the model achieves 95.3% accuracy and uses only 9.4 kB of RAM, demonstrating viability for resource‐

Surveillance of Rift Valley Fever in Iran between 2001 and 2011

All Results Journals: Biol, 2013
Rift Valley fever virus (RVFV) is an acute zoonotic viral disease that mostly affects ruminants with an occasional spillover as human infection. Following the outbreak of RVF in Saudi Arabia in 2000, surveillance of both animal and human population in ...

Ten years since the last Chikungunya virus outbreak in Italy. History repeats itself [PDF]

, 2017
The prevalence of Arbovirus (arthropod-borne virus) infections is increasing worldwide. Recently, new clusters of autochthonous cases have been reported in countries with temperate climates where the competent vector is present.

Crimean-Congo haemorrhagic fever among healthcare workers in Iran 2000–2023, a report of National Reference Laboratory

BMC Infectious Diseases
Background Crimean-Congo haemorrhagic fever (CCHF) is a lethal acute viral zoonosis with a case fatality rate of 5–50%. Due to the potential of human-to human transmission of the disease, healthcare workers (HCWs) are at risk of occupational exposure to ...

Endogenous non-retroviral elements in genomes of Aedes mosquitoes and vector competence

Emerging Microbes and Infections, 2019
Recent extensive (re)emergences of arthropod-borne viruses (arboviruses) such as chikungunya (CHIKV), zika (ZIKV) and dengue (DENV) viruses highlight the role of the epidemic vectors, Aedes aegypti and Aedes albopictus, in their spreading. Differences of

A clustered regularly interspaced palindromic repeat‐Cas12a‐based assay for rapid dengue virus monitoring in mosquito and clinical samples facilitating global collaborative surveillance and risk assessment to block dengue spreading

Interdisciplinary Medicine, EarlyView.
The RAA‐Cas12a assay outperforms real‐time PCR in sensitivity (92.3%) while matching its specificity (100%) for dengue virus detection in clinical samples. It effectively identifies DENV in mosquitoes, with field data correlating to local outbreaks. This rapid, simple, and precise method serves as an early warning tool for dengue management.
