Fifteen years of mosquito data implicate species most likely to transmit West Nile virus in Iowa

(Iowa State University) A study published this week that analyzed 15 years of mosquito surveillance data shows Iowa's western counties experience a higher abundance of the species thought to most commonly carry West Nile virus. Culex tarsalis, the mosquito species most often implicated in West Nile transmission, usually becomes most active in early September. The data support similar findings in Nebraska and South Dakota.

We analyzed m6A modification across the transcriptome following infection by dengue virus (DENV), Zika virus (ZIKV), West Nile virus (WNV), and hepatitis C virus (HCV). We found that infection by these viruses in the Flaviviridae family alters m6A modification of specific cellular...

BOSTON (CBS) – The third human case of West Nile Virus has been announced by the Massachusetts Department of Public Health. A man in his 60s from Middlesex County was exposed to the virus last month. “We continue to emphasize the need for people to protect themselves from mosquito bites,” said Public Health Commissioner Monica Bharel, MD, MPH. “Although mosquito populations are declining, some risk will continue until the first hard frost.” CHECK: Map Of Communities At Risk For EEE, WNV The other two human cases of WNV this year were another man in his 60s from Middlesex County and a man in ...

This report describes and characterizes three novel RNA viruses isolated from dead birds collected during West Nile virus surveillance in Harris County, TX, USA (the Houston metropolitan area). The novel viruses are identified as members of the families Nyamaviridae, Orthomyxoviridae, and Peribunyaviridae and have been designated as San Jacinto virus, Mason Creek virus, and Buffalo Bayou virus, respectively. Their potential public health and/or veterinary importance are still unknown.

Publication date: December 2019Source: Molecular Phylogenetics and Evolution, Volume 141Author(s): Serafeim C. Chaintoutis, Anna Papa, Danai Pervanidou, Chrysostomos I. DovasAbstractWest Nile virus (WNV) is an arbovirus causing neuroinvasive disease to humans and equines. Since 2004, lineage 2 WNV strains have been identified in Europe and have been implicated in severe outbreaks, with that of 2018 exceeding the total number from the previous seven years. The aim of this study was to explore the evolutionary process that shapes the genetic diversity of lineage 2 WNV strains (belonging to the Central European/Hungarian subc...

Authors: Das BK, Agasti N, Singh YKS, Midya A Abstract Systemic capillary leak syndrome (SCLS) is a very rare disorder characterized by hypotension with heamoconcentration, hypoalbuminemia without albuminuria and generalized edema, the etiology of which are snake bites, viral heamorrhagic fever, drugs, sepsis, upper respiratory tract infection, Hanta virus and West Nile virus infection and serum paraproteinemia. Typically, the syndrome manifests in two phases: initial capillary leak phase characterized by edema, serous effusion, hypotension which is followed by phase of volume overload or recruitment phase. Treatme...

Pierre Boulanger Saw-See Hong The cellular response to the recombinant NS1 protein of West Nile virus (NS1WNV) was studied using three different cell types: Vero E6 simian epithelial cells, SH-SY5Y human neuroblastoma cells, and U-87MG human astrocytoma cells. Cells were exposed to two different forms of NS1WNV: (i) the exogenous secreted form, sNS1WNV, added to the extracellular milieu; and (ii) the endogenous NS1WNV, the intracellular form expressed in plasmid-transfected cells. The cell attachment and uptake of sNS1WNV varied with the cell type and were only detectable in Vero E6 and SH-SY5Y cells. Addition of ...

The incidence of neuroinvasive disease linked to West Nile virus (WNV) infections was 25% higher in 2018 (0.51 per 100  000) than the median incidence between 2008 and 2017 (0.41 per 100 000), according to a CDC report.

Specific structures in mRNA can stimulate programmed ribosomal frameshifting (PRF). PRF efficiency can vary enormously between different stimulatory structures, but the features that lead to efficient PRF stimulation remain uncertain. To address this question, we studied the structural dynamics of the frameshift signal from West Nile virus (WNV), which stimulates...

BOSTON (CBS) — A man in his 70s has become the second person to die and the 10th person to be diagnosed with the Eastern Equine Encephalitis (EEE) virus in Massachusetts, the Department of Public Health said Friday. The man was a Freetown resident, according to the town. There are 35 communities at critical risk, 40 at high risk, and 128 at moderate risk for EEE. Check: Map Of Communities At Risk Additionally, a second person, a man in his 50s from Plymouth County, was diagnosed with West Nile Virus. Health officials urged the public to use bug spray, reduce exposed skin and stay indoors from dusk to dawn when m...
