    摘要: The invention provides the discovery and characterization of a novel arterivirus protein (nsp2TF), whose expression is dependent on -2 ribosomal frameshifting at a site located in the nsp2 coding region. The coding region for the unique TF domain of nsp2TF overlaps the part of ORF1a that encodes the transmembrane region of nsp2 in arteriviruses, including PRRSV, LDV and SHFV. Mutations affecting the expression of nsp2TF impair PRRSV replication and result in a smaller plaque phenotype. Provided herein are arteriviruses that display reduced translation of nsp2TF and/or altered translation of one or more downstream products, arteriviruses in which nsp2TF function is reduced and/or absent, and vaccines comprising said arteriviruses. Also provided herein are diagnostic methods, methods for identifying compounds that inhibit -2 frameshifting, and gene expression tools for eukaryotic systems utilizing -2 frameshifting.

    摘要: This invention provides kits, devices, and methods for the detection of antibodies that recognize one or more proteins and/or antigens from porcine reproductive and respiratory syndrome virus (PRRSV). The antibodies may be in a biological fluid of a PRRSV infected or at risk subject. The invention may be advantageously applied to both the diagnosis and prevention of PRRSV infection.

    摘要: This document provides methods and materials related to assessing organisms for the presence or absence of anti-virus antibodies. For example, this document provides methods and materials that can be used to determine whether or not an organism (e.g., a member of a swine species such as a pig) contains anti-PRRS virus antibodies. In other embodiments, this document provides methods and materials that can be used to determine if a particular organism received a vaccine version of a virus, was infected with a naturally-occurring version of the virus, or is naïve with respect to the virus.
