UverskyAbstractThe Nipah Virus (NiV) was first isolated during a 1998–9 outbreak in Malaysia. The outbreak initially infected farm pigs and then moved to humans from pigs with a case-fatality rate (CFR) of about 40%. After 2001, regular outbreaks occurred with higher CFRs (∼71%, 2001–5, ∼93%, 2008–12). The spread arose from drinking virus-laden palm date sap and human-to-human transmission. Intrinsic disorder analysis revealed strong correla...

In this study, NiV-G protein served as the target immunogen to activate NiV-specific cellular immune responses. Modified Vaccinia virus Ankara (MVA), a safety-tested strain of vaccinia virus for preclinical and clinical vaccine research, was used for the generation of MVA–NiV-G candidate vaccines expressing different versions of recombinant NiV-G. Overlapping peptides covering the entire NiV-G protein were used to identify major histocompatibility complex class I/II-restricted T cell responses in type I interferon receptor-deficient (IFNAR−/−) mice after vaccination with the MVA–NiV-...

In this study, we generated two recombinant RABVs, rERAG333E/NiVG and rERAG333E/NiVF, expressing the NiV Malaysian strain attachment glycoprotein (NiV-G) or fusion glycoprotein (NiV-F) gene based on the rERAG333E vector platform. Both rERAG333E/NiVG and rERAG333E/NiVF displayed growth properties similar to those of rERAG333E and caused marked syncytia formation after co-infection in BSR cell culture. Adult and suckling mice intracerebrally inoculated with the recombinant RABVs showed NiV-G and NiV-F expression did not increase the virulence of rERAG333E. Oral vaccination with rERAG333E/NiVG either singularly or combined wi...

, Norheim G Abstract Today's world is characterized by increasing population density, human mobility, urbanization, and climate and ecological change. This global dynamic has various effects, including the increased appearance of emerging infectious diseases (EIDs), which pose a growing threat to global health security.Outbreaks of EIDs, like the 2013-2016 Ebola outbreak in West Africa or the current Ebola outbreak in Democratic Republic of the Congo (DRC), have not only put populations in low- and middle-income countries (LMIC) at risk in terms of morbidity and mortality, but they also have had a significant impa...

Nipah virus is an emerging pathogenic paramyxovirus responsible for sporadic and isolated outbreaks of severe respiratory and neurologic disease in Southern Asia. As a zoonotic virus, disease can manifest in both animals and human with indigenous fruit bats acting as natural reservoirs of the virus. The effects of viral infection vary from acute respiratory distress to fatal encephalitis. There are currently no approved therapeutics or vaccines against the virus, and growing concerns that this highly pathogenic infection has the potential to cause larger epidemics capable of inflicting significant mortality burden.Like the...

Authors: Ochani RK, Batra S, Shaikh A, Asad A Abstract The Nipah virus was discovered twenty years ago, and there is considerable information available regarding the specificities surrounding this virus such as transmission, pathogenesis and genome. Belonging to the Henipavirus genus, this virus can cause fever, encephalitis and respiratory disorders. The first cases were reported in Malaysia and Singapore in 1998, when affected individuals presented with severe febrile encephalitis. Since then, much has been identified about this virus. These single-stranded RNA viruses gain entry into target cells via a process k...
