Abstract: 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.

Abstract: A nucleotide sequence is provided for the VR-2332 virus, which is capable of causing Porcine Reproductive and Respiratory Syndrome. The nucleotide sequence includes protein coding regions that are inserted into recombinant vectors for the host expression of viral proteins according to a variety of vaccination techniques. Diagnostic assays utilize fragmentary sequences or oligonucleotides to selectively identify the VR-2332 nucleic acids by hybridization or PCR amplification reactions that distinguish VR-2332 nucleotide sequences from other PRRS-causative viruses which are immunologically distinct from VR-2332.

Abstract: A highly-antigenic, recombinant polypeptide of a molecular weight of about 110-kD by SDS-PAGE is disclosed, which is derived by transforming E. coli with a 7.1 kB DNA fragment from EcoR1-digested B. burgdorferi DNA, followed by identification of cloned transformants expressing polypeptides which bind to anti-B. burgdorferi antibodies.
