Clade 2.3.2.1 H5N1 avian influenza viruses circulate at the interface of migratory and domestic birds around Qinghai Lake in China

During 2012-2015, six H5N1 avian influenza viruses were isolated from domestic birds and the environment around Qinghai Lake. Phylogenetic analysis of HA genes revealed that A/chicken/Gansu/XG2/2012 (CK/GS/XG2/12) belonged to clade 2.3.2.1a, while A/environment/Qinghai/1…

Evidence of reduced viremia, pathogenicity and vector competence in a re-emerging European strain of bluetongue virus serotype 8 in sheep

The outbreak of bluetongue virus (BTV) serotype 8 (BTV-8) during 2006-2009 in Europe was the most costly epidemic of the virus in recorded history. In 2015, a BTV-8 strain re-emerged in France which has continued to circulate since then. To examine anecdotal reports of…

Insights from the crystal structure of the chicken CREB3 bZIP suggest members of the CREB3 subfamily transcription factors may be activated in response to oxidative stress

cAMP response element binding protein 3 (CREB3) is an endoplasmic reticulum (ER) membrane-bound transcription factor, which belongs to the basic leucine zipper (bZIP) superfamily of eukaryotic transcription factors. CREB3 plays a role in the ER-stress induced unfolded…

Pirbright scientists identify how a single bird flu protein can increase period of infection

New research led by scientists at The Pirbright Institute has shown how an influenza virus protein, called PB1-F2, is able to shut down two pathways of the chicken immune response to increase the length of time the virus can be transmitted. The PB1-F2 protein of influenza…

Spindle-E acts antivirally against alphaviruses in mosquito cells

Mosquitoes transmit several human- and animal-pathogenic alphaviruses (Togaviridae family). In alphavirus-infected mosquito cells two different types of virus-specific small RNAs are produced as part of the RNA interference response: short-interfering (si)RNAs and PIWI…

RNA interference restricts Rift Valley fever virus in multiple insect systems

The emerging bunyavirus Rift Valley fever virus (RVFV) is transmitted to humans and livestock by a large number of mosquito species. RNA interference (RNAi) has been characterized as an important innate immune defense mechanism used by mosquitoes to limit replication of…
