Comparison of enzyme linked immunosorbent assay systems

Nov 22, 2018 · Rift Valley Fever (RVF) is a mosquito borne viral zoonosis. To detect RVF virus (RVFV) infection, indirect immunoglobulin G (IgG) and immunoglobulin M (IgM) enzyme linked immunosorbent assays (ELISAs) which utilize recombinant RVFV nucleocapsid (RVFV N) protein as assay antigen, have reportedly been used, however, there is still a need to develop more sensitive and specific methods of Sero prevalence and spatial distribution of Rift Valley Jun 14, 2018 · Rift Valley Fever (RVF) is a viral zoonotic fever caused by RVF virus (RVFV), a member of the genus Phlebovirus in the family Bunyaviridae [1,2,3].It is an illness characterized by deaths and abortion storms primarily in goats, sheep, and cattle [].The disease also affects humans, dogs, camels and wildlife [].Wild animals such as African buffalo (Syncerus caffer), black rhino (Diceros bicornis Validation of an IgM antibody capture ELISA based on a 1. Introduction. Rift Valley fever virus (RVFV) belongs to the Phlebovirus genus, family Bunyaviridae and was first identified in 1930 during an outbreak of sudden deaths and abortions among sheep in the greater Rift Valley of Kenya (Daubney et al., 1931, Daubney and Hudson, 1932).The virus is primarily transmitted by mosquitoes and causes a potentially severe disease in humans and livestock

After the devastating West African Ebola epidemic in 201316, which alone claimed the lives of more than 11,000 people and had a comprehensive economic and social burden estimated at over US$53 billion (or more than $1.8 million per case), the global need for an organization that could finance and coordinate the development of vaccines against EIDs was

Two monoclonal antibodies against glycoprotein Gn

Most recently, rabbit and human derived monoclonal antibodies against glycoprotein Gn were shown to be protective in mice against Rift Valley fever infections [15, 16]. Gn is a type I transmembrane protein which forms together with glycoprotein Gc non covalently linked heterodimers on the lipid bilayer envelope of the virion and allows virus Evaluation of an Indirect Enzyme Linked Immunosorbent The increasing risk of Rift Valley fever virus (RVFV) infection as a global veterinary and public health threat demands the development of safe and accurate diagnostic tests. The aim of this study was to assess the suitability of a baculovirus eion system to produce recombinant RVFV nucleoprotein (N) for use as serodiagnostic antigen in an indirect enzyme linked immunosorbent assay (ELISA).Rift Valley Fever, Sudan, 2007 and 2010 Volume 19 To elucidate whether Rift Valley fever virus (RVFV) diversity in Sudan resulted from multiple introductions or from acquired changes over time from 1 introduction event, we generated complete genome sequences from RVFV strains detected during the 2007 and 2010 outbreaks. Phylogenetic analyses of small, medium, and large RNA segment sequences indicated several genetic RVFV

A survey of rift valley fever and associated risk factors

Jun 10, 2016 · Rift valley fever (RVF) is a mosquito borne viral disease of domestic livestock and wild ruminants. In camels RVF may cause abortion among pregnant camels, but is most often asymptomatic among other camels. In this study, a seroepidemiological survey was conducted to determine the prevalence of RVFV antibodies and to identify the potential risk factors associated with RVFV Rift Valley fever virusDiagnosis and vaccinesJun 24, 2011 · 1.

Further studies are warranted to investigate the possible mechanisms. Our findings have implications for implementation of preventive measures, and evidence based information to the public in endemic countries should be strongly recommended during Rift Valley fever Severe Human Illness Caused by Rift Valley Fever Virus in Rift Valley fever (RVF) is a vector borne viral disease caused by RVF virus (RVFV), a member of the Bunyaviridae family and Phlebovirus genus that primarily affects domestic ruminants, causing large epizootics with high mortality rates in young animals and abortions in affected female animals [].The virus was discovered in 1930 during an outbreak that affected livestock in East Africa [], and

Rift Valley fever (RVF) is an emerging zoonosis in Africa which has spread to Egypt, the Arabian Peninsula, Madagascar, and Comoros. RVF virus (RVFV) ( Bunyaviridae family, Phlebovirus genus) causes a wide range of symptoms in humans, from benign fever to fatal hemorrhagic fever.
