Modulation of arbovirus infection by mosquito saliva

Access Microbiology, 2019
Arboviruses constitute a major public health problem, in particular mosquito-borne arboviruses that continue to emerge and re-emerge. Arbovirus infection of mammals is enhanced by the presence of a mosquito bite at the inoculation site, in comparison to virus experimentally administered by needle inoculation in the absence of a bite.

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 ...

An All‐in‐One Metabarcoding Approach to Mosquito and Arbovirus Xenosurveillance

Molecular Ecology Resources, EarlyView.
ABSTRACT Next‐generation sequencing (NGS) has the potential to transform mosquito‐borne disease surveillance but remains under‐utilised. This study introduces a comprehensive multi‐loci metabarcoding‐based MX (molecular xenomonitoring) approach to mosquito and arbovirus surveillance, enabling parallel identification of mosquito vectors, circulating ...

Detection and phylogenetic characterization of arbovirus dual-infections among persons during a chikungunya fever outbreak, Haiti 2014

PLoS Neglected Tropical Diseases, 2018
In the context of recent arbovirus epidemics, questions about the frequency of simultaneous infection of patients with different arbovirus species have been raised.

Virtual dissection of Aedes aegypti mosquito using phase‐contrast synchrotron microtomography

Journal of Microscopy, EarlyView.
Abstract In this paper, in‐line phase‐contrast synchrotron microtomography was used to study the morphology of adult Aedes aegypti. These specimens are vectors of several arboviruses, causing dengue, chikungunya, Zika and yellow fever. The morphological details of this insect species are still incomplete and insufficient.

Field studies of Culex mosquitoes in Tanzania and Kenya: A systematic review motivated by changing Rift Valley fever virus transmission patterns

Medical and Veterinary Entomology, EarlyView.
There were 275 studies reporting Culex abundance, 17 of which explicitly stated the motivation for the study was RVFV. Despite most studies being motivated by other topics, there was good coverage of studies reporting mosquito sampling in areas associated with the risk of RVFV outbreaks. Studies were c.

Schmallenberg virus: emergence of an Orthobunyavirus among ruminants in Western Europe [PDF]

, 2012
Recently, a novel virus has been identified among ruminants in Western Europe. This virus, the so-called Schmallenberg virus, belongs to the family Bunyaviridae, genus Orthobunyavirus, serogroup Simbu and is closely related to Akabane, Aino and Shamonda ...

Predicting the Spatial Dynamics of Wolbachia Infections in Aedes Aegypti Arbovirus Vector Populations in Heterogeneous Landscapes

bioRxiv, 2018
A promising strategy for reducing the transmission of dengue and other arboviral human diseases by Aedes aegypti mosquito vector populations involves field introductions of the endosymbiotic bacteria Wolbachia.

Reproducibility and relevance in insect-arbovirus infection studies

Current Opinion in Insect Science, 2018
Experimental infections of insects with arboviruses are performed to achieve a variety of objectives but principally to draw inferences about the potential role of field populations in transmission or to explore the molecular basis of vector-pathogen interactions.
