Term Description

Percent genomic homology between a new isolated PRRS virus strain and a PPRS vaccine strain (e.g. Lelystad, Fostera, IngelvacMLV, IngelvacATP, PrimePac and Prevacent) is based on the number of matching amino acids per total amino acids sequenced in the open reading frame 5 (ORF5) gene. The more homologous the ORF5 gene sequences, the more closely the variants are related. It is thought that sequence homology between isolates and vaccines will predict vaccine efficacy, however this is currently debated since little is known about the immune response to PRRS virus.

Part Description

LP150045-5   Sequencing
Sequencing is a method used to determine the sequence of individual genes, larger genetic regions (i.e. clusters of genes or operons), full chromosomes or entire genomes. Historically, most sequencing has been performed using the chain termination method developed by Frederick Sanger in 1977. PMID: 271968 Sequencing technologies have improved dramatically, making them cheaper, faster, and more accurate. Next-generation sequencing (NGS), also known as high-throughput sequencing, deep sequencing, and second-generation sequencing, is a type of technology that uses parallel sequencing of multiple small fragments of DNA to determine sequence. This "high-throughput" technology has increased the speed and amount of DNA sequenced at a significantly reduced cost. PMID: 18576944 Several NGS platforms (ie, sequencing instruments and associated reagents) have been developed. Third-generation sequencing is another methodology currently under development that uses parallel sequencing similar to NGS. In contrast to NGS, third-generation sequencing uses single DNA molecules rather than amplified DNA as a template. PMID: 20858600 Source: Regenstrief LOINC
