West Nile virus (WNV) is endemic in southeastern Romania and, after the unprecedented urban epidemic in Bucharest in 1996 caused by lineage 1 WNV, cases of West Nile fever have been recorded every year. Furthermore, a new outbreak occurred in 2010, this time produced by a lineage 2 WNV belonging to the Eastern European clade (Volgograd 2007-like strain), which was detected in humans and mosquitoes in the following years.
Human infections caused by West Nile Virus (WNV) mostly remain subclinical and self limited. However, nearly 20% infected people suffer from febrile illness and very few of them (
Changes in climatic conditions are hypothesized to play a role in the increasing number of West Nile Virus (WNV) outbreaks observed in Europe in recent years.
West Nile Virus (WNV) is mosquito-borne virus that is endemic in Israel. In 2015, national disease surveillance demonstrated a sharp increase in disease cases, with 149 cases diagnosed.
In 2017, we isolated and identified West Nile virus (WNV) lineage 2 from two dead captive goshawks (Accipiter gentilis), for the first time in the Czech Republic. Goshawk might serve as an early indicator species for the ongoing WNV emergence in several European countries.
In Nigeria not much is known about West Nile virus (WNV) in pigeons. This study determined the involvement of household-reared pigeons in the circulation of WNV in Nigeria.
To determine the seroprevalence of antibodies against Dengue virus (DENV) and West Nile Virus (WNV) in the human population of the Bolivian Chaco, we tested 256 inhabitants of 2 rural communities. The seroprevalence, confirmed by Plaque Reduction Neutralization Test, was 7.8%, and 2.7% for DENV and WNV, respectively. This article is protected by copyright. All rights reserved.
Elsberg syndrome (ES) is a rarely recognized cause of cauda equina syndrome and lower thoracic myelitis, mainly linked to reactivation, or occasionally primary, infection with herpes simplex virus type 2. West Nile virus neuroinvasive disease is rarely considered in the differential diagnosis of patients with ES.
Flavivirus diseases such as dengue fever (DENV), West Nile virus (WNV), Zika and yellow fever represent a substantial global public health concern. Preexisting chronic conditions such as cardiovascular diseases, diabetes, obesity, and asthma were thought to predict risk of progression to severe infections.
West Nile virus (WNV) and Flanders virus (FLAV) co-occur in regions of North America. Because both viruses are maintained in a transmission cycle involving Culex mosquitoes and birds, screening mosquitoes for FLAV has been suggested as an enhancement to WNV surveillance and epidemic prediction. Using samples collected in 2010 and 2012 in Chicago, IL, USA, we demonstrate the presence of FLAV in four out of 287 (1.4%) Culex pools. We estimated minimum infection rates for WNV and FLAV to be 5.66 and 1.22 in 20...
Emerging and re-emerging arthropod-borne viruses (arboviruses) cause human and animal disease globally. Field and laboratory investigation of mosquito-borne arboviruses requires analysis of mosquito samples, either individually, in pools, or a body component, or secretion such as saliva. We assessed the applicability of mosquito excreta as a sample type that could be utilized during studies of Ross River and West Nile viruses, which could be applied to the study of other arboviruses.
A discrete-time model describing the west nile virus transmission among the mosquito, wild bird, and domestic bird populations is constructed. The expressions for the basic reproduction number R and the disease-free fixed point of the model are computed. The local stability of the disease-free fixed point is established based on R. Optimal control theory is used to devise the most effective administration profile of mosquito larvicide, mosquito adulticide and domestic bird-protection in controlling the viru...
West Nile virus (WNV) is a positive-sense single-stranded RNA flavivirus belonging to the Japanese encephalitis virus (JEV) serocomplex of the Flaviviridae family and causes mosquito-borne infections. Although most human infection cases are asymptomatic, approximately one in 150 infected individuals develops meningoencephalitis, with a mortality rate of 4-14%. While the development of human neutralizing antibody therapeutics against WNV is strongly anticipated, WNV is difficult to study in conventional labo...
West Nile virus (WNV) is an emerging mosquito-borne virus which is responsible for severe and fatal encephalitis in humans and for which there is no licensed vaccine or therapeutic available to prevent infection. The envelope domain III protein (EDIII) of WNV was over-expressed in Escherichia coli and purified using a two-step chromatography process which included immobilized metal affinity chromatography and ion exchange chromatography. E. coli cells were grown in a bioreactor to high density using batch a...
This paper is concerned with a strongly-coupled elliptic system, which describes a West Nile virus (WNv) model with cross-diffusion in a heterogeneous environment. The basic reproduction number is introduced through the next generation infection operator and some related eigenvalue problems. The existence of coexistence states is presented by using a method of upper and lower solutions. The true positive solutions are obtained by monotone iterative schemes. Our results show that a cross-diffusive WNv model ...
West Nile virus (WNV) is a single-stranded RNA flavivirus and is a major cause of viral encephalitis worldwide. Experimental models of WNV infection in mice are commonly used to define acute neuroinflammatory responses in the brain. Alpha-synuclein (Asyn) is a protein of primarily neuronal origin and is a major cause of Parkinson's disease (PD), a disorder characterized by loss of dopaminergic neurons. Both WNV and PD pathologies are largely mediated by inflammation of the central nervous system (neuroinfla...
The second largest outbreak of West Nile encephalitis and West Nile fever ever recorded occurred in the United States (U.S) in the summer of 2012. The outbreak was related to the widespread circulation of closely related clades, or groups, of West Nile virus (WNV) into multiple states where they were not previously found. Whether the invading 2012 strains were able to circulate and overwinter in states with their own endemic population of WNV is unknown and the effect of viral genetics on adaptation and per...
West Nile virus (WNV) infection has been reported to promote myasthenia gravis (MG) and various other diseases that have a presumed autoimmune pathogenesis. Molecular mimicry between WNV proteins and host proteins has been postulated as the major mechanism for WNV-triggered breaking of immunological self-tolerance. We present a patient with stable ocular MG and positive anti-acetylcholine receptor antibodies who progressed to myasthenic crisis after WNV neuroinvasive disease. In this case of stable autoimmu...
Eastern Europe (EE) has been severely affected by mosquito-borne viruses (moboviruses). In this review, we summarize the epidemiology of moboviruses, with particular attention to West Nile virus (WNV). The study of WNV human cases in EE between 2010 and 2016, revealed that the epidemiology of WNV in EE is complex with the combination of introduction of different WNV strains from lineages 1 and 2, and the establishment of endemic cycles. We found a positive correlation between the risk of WNV re-emergence in...
The West Nile virus (WNV) has spread throughout the world causing neuroinvasive diseases with no treatments available. The viral NS2B-NS3 protease is essential for WNV survival and replication in host cells and is a promising drug target. Through an enzymatic screen of the National Institute of Health clinical compound library, we report the discovery of zafirlukast, an FDA approved treatment for asthma, as an inhibitor for the WNV NS2B-NS3 protease. Zafirlukast was determined to inhibit the protease throug...
In recent years, we have observed the emergence and reemergence of a number of arthropod-borne viruses (arboviruses). Zika virus is the most recent addition to this group, first causing sporadic cases of uncomplicated febrile illness followed by sizeable outbreaks in the Pacific. However, the epidemiology and clinical features of Zika virus infection have changed rapidly and dramatically; it is now recognized as causing Guillain-Barré syndrome (GBS) in children and adults and congenital abnormalities in in...
Positive-sense RNA virus intracellular replication is intimately associated with membrane platforms that are derived from host organelles and comprised of distinct lipid composition. For flaviviruses, such as West Nile virus strain Kunjin virus (WNVKUN) we have observed that these membrane platforms are derived from the endoplasmic reticulum and are rich in (at least) cholesterol. To extend these studies and identify the cellular lipids critical for WNVKUN replication we utilized a whole cell lipidomics app...
We tested sera of 24 free-ranging European brown bears ( Ursus arctos) from six regions of Slovakia for antibodies to 10 viral agents. We tested sera by an indirect fluorescence antibody test for antibodies to canine distemper virus (CDV), canine coronavirus (CCV), canine parvovirus type 2 (CPV-2), canine adenovirus, canine parainfluenza virus type 2 (CPIV-2), and canine herpesvirus type 1 (CHV-1). We used an enzyme-linked immunosorbent assay for detection of antibodies to hepatitis E virus, bluetongue viru...
This study detected West Nile virus (WNV) infection in serum samples of patients clinically diagnosed with viral encephalitis in the Japanese encephalitis virus (JEV) endemic area (seven provinces) and JEV nonendemic area (Xinjiang province) in China from 2011 to 2012. In JEV endemic areas, there were 22 positive cases of WNV immunoglobulin M (IgM) antibody in serum specimens of 65 JEV patients (JEV IgM antibody positive) in the acute phase, whereas WNV IgM antibodies were not detected in serum specimens of...
