摘要:
A rapid immunoassay method and apparatus for detecting foot and mouth disease virus are disclosed. The method and test device permit pen-side testing of animals and provide test results within a relatively short time period. In a preferred embodiment, the method and apparatus provide a means for differentiating between FMDV-infected and FMDV-vaccinated animals.
摘要:
The present invention relates to nucleic acids comprising:
(a) sequences of a replication competent transmissible gastroenteritis virus (TGEV), which sequences encode a TGEV replicase under the control of expression regulatory sequences so that expression of the replicase in a cell containing the nucleic acid will initiate replication of the nucleic acid and thus increase the number of nucleic acids in the cell; and (b) sequences encoding one or more proteins of foot and mouth disease virus (FMDV), wherein the one or more proteins are capable of associating into a virus-like particle (VLP) that does not contain any infectious nucleic acid.
The present invention further relates to vectors, virus particles and host cells comprising these nucleic acids as well as their use for the preparation of pharmaceutical compositions, specifically for the preparation of vaccines.
摘要:
A virus in the atmosphere can be precisely detected on a real time basis. At a main pipeline 8, a dust removing unit 1, an atomization unit 4, a fluorescence measuring unit 5 in which a laser beam is irradiated, and a suction pump 7 are arranged in this order, and a suctioned air current is generated in the main pipeline 8 through the suction pump 7. Meanwhile, a diffusion unit 3 includes a liquid flow path 35 and a gas flow path 34 formed in parallel to the liquid flow path, and an atmosphere and an aqueous solution containing a fluorescent antibody F pass through the gas flow path 34 and the liquid flow path 35, respectively. The aqueous solution is flown into the atomization unit 4 through a guide passage 40 branched from a branch part that is formed at an outlet side of the flow paths 34 and 35 and discharges the gas and the aqueous solution after separating the gas and the aqueous solution. A mist group is flown into the fluorescence measuring unit 5. Since a fluorescence intensity of the mist M when the virus V exists is higher than a fluorescence intensity when no virus V exists, the virus V can be detected by monitoring the fluorescence intensity.
摘要:
Provided herein is a nucleic acid comprising consensus amino acid sequence of foot-and-mouth disease FMDV VP1-4 coat proteins of FMDV substypes A, Asia 1, C, O, SAT1, SAT2, and SAT3 as well as plasmids and vaccines expressing the sequences. Also provided herein is methods for generating an immune response against one or more FMDV subtypes using the vaccine as described above as well as methods for deciphering between vaccinated mammals with the vaccine and those that are infected with FMDV.
摘要:
The present invention provides a foot and mouth disease (FMD) vaccine comprising a vaccinating entity comprising or capable of expressing a foot and mouth disease virus (FMDV) VP1 polypeptide having a deletion of at least seven amino acids in the G-H loop such that the VP1 polypeptide lacks an RGD motif. The present invention also provides a method for preventing and/or treating FMD in a subject which comprises the step of administration of such a vaccine.
