摘要:
The present disclosure provides compositions and methods for detecting the presence of neutralizing antibodies in a sample. Unlike conventional assays, the methods provided herein do not require the use of live virus or virus pseudoparticles to identify neutralizing antibodies.
摘要:
The present invention concerns wild-strains of Chikungunya virus isolated from patients exhibiting severe forms of infection and stemming from a human arbovirosis epidemy. The present invention also concerns polypeptide sequences and fragment thereof derived from their genome, the polynucleotide encoding same and their use as diagnostic products, as vaccine and/or as immunogenic compositions.
摘要:
The present invention provides pseudoinfectious alphavirus particles and methods of making them and using them to produce an immune response to an alphavirus in a subject.
摘要:
There is described a novel virus which is the causative agent of fish pancreatic disease, which is a serious disease affecting Atlantic salmon. A method of isolating the virus through co-cultivation of infected tissues following by passage is described and an isolated strain of the virus has been deposited. The use of the virus, or proteins or polypeptide derived therefrom as a vaccine or in diagnosis is described, together with genetically engineered constructs.

摘要:
A DNA comprises a cDNA clone coding for an infectious Venezuelan Equine Encephalitis Virus RNA transcript and a heterologous promoter sequence positioned upstream from the cDNA clone and operatively associated therewith. A method of making a live attenuated Togavirus useful as a vaccine, and cDNA clones which code for attenuated Togaviruses, is also disclosed.
摘要:
A vaccine composition for prophylaxis and treatment of Chikungunya virus infections is disclosed which is capable of conferring immunity against any genotypic variants of the Chikungunya virus. More particularly the invention discloses particular nucleotide sequences and their translated proteins thereof, which may be expressed as Virus Like Particles which for use as a vaccine antigens against Chikungunya virus infections. The compositions disclosed in this invention are also protective against any genotypic variants of the Chikungunya virus which may be propagated by any suitable vector of the disease including Aedis albopictus and Aedis aegypti.
摘要:
Embodiments are directed compositions related to Eilat virus and uses thereof. Certain aspects are directed to the detection of non-Eilat entities using a chimeric Eilat alphavirus as a capture agent.
摘要:
The present invention relates to enveloped RNA viruses. The invention in particular relates to the generation of superior antigens for mounting an immune response by first identifying then mutating the immunosuppressive domains in fusion proteins of enveloped RNA viruses resulting in decreased immunosuppressive properties of viral envelope proteins from the viruses.
