Analytical and clinical evaluation of a duplex RT-qPCR assay for the detection and identification of o’nyong-nyong and chikungunya virus

Emerging Microbes and Infections
The mosquito-borne alphavirus o’nyong-nyong virus (ONNV) has proven its potential to cause major human outbreaks. On the African continent, ONNV causes unspecific febrile illness and co-circulates with the close relative chikungunya virus (CHIKV).

Mutation of CD2AP and SH3KBP1 binding motif in alphavirus nsP3 hypervariable domain results in attenuated virus [PDF]

, 2018
Infection by Chikungunya virus (CHIKV) of the Old World alphaviruses (family Togaviridae) in humans can cause arthritis and arthralgia. The virus encodes four non-structural proteins (nsP) (nsP1, nsp2, nsP3 and nsP4) that act as subunits of the virus ...

Destabilization of α-helical structure in solution improves bactericidal activity of antimicrobial peptides: Opposing effects on bacterial and viral targets [PDF]

, 2016
We have previously examined the mechanism of antimicrobial peptides on the outer membrane of vaccinia virus. Here we show that the formulation of peptides LL37 and magainin-2B amide in polysorbate 20 (Tween-20™) results in greater reductions in virus ...

Shrubs and trees as natural insect protection for grazing animals in Switzerland and the alpine region: A systematic review of in vitro, in vivo and clinical trials Sträucher und Bäume als natürlicher Insektenschutz für Weidetiere in der Schweiz und im Alpenraum: Eine systematische Literaturübersicht über in vitro‐, in vivo‐ und klinische Studien

Medical and Veterinary Entomology, EarlyView.
Biting or irritating insects are a threat to the health and welfare of grazing animals. This systematic review reveals that several shrubs and bushes growing in the alpine area have insecticidal, insect‐repellent and/or attractant properties. The alder Alnus glutinosa, juniper Juniperus communis, spruce Picea abies and walnut Juglans regia are ...

Sindbis virus interferes with dengue 4 virus replication and its potential transmission by Aedes albopictus

Parasites & Vectors, 2015
Background Mosquitoes transmit a number of arboviruses associated with disease outbreaks in humans and other animals. The majority of medically important arboviruses belong to three families: Togaviridae, Flaviviridae and Bunyaviridae. Several members of

Group size and nest spacing affect Buggy Creek virus (Togaviridae: Alphavirus) infection in nestling house sparrows. [PDF]

PLoS ONE, 2011
The transmission of parasites and pathogens among vertebrates often depends on host population size, host species diversity, and the extent of crowding among potential hosts, but little is known about how these variables apply to most vector-borne ...

Sequelae and Animal Modeling of Encephalitic Alphavirus Infections

Viruses, 2023
Eastern (EEEV), Venezuelan (VEEV), and western equine encephalitis viruses (WEEV) are members of the genus Alphavirus, family Togaviridae. Typically spread by mosquitoes, EEEV, VEEV, and WEEV induce febrile illness that may develop into more severe ...
