Suid herpesvirus 1 (SuHV-1) is the causative agent of pseudorabies (PR), a disease of great importance due to the huge losses it causes in the swine industry. The aim of this study was to determine a method for genotyping SuHV-1 based on partial sequences of the gene coding for glycoprotein C (gC) and to elucidate the possible reasons for the variability of this region. A total of 109 gCsequences collected from GenBank were divided into five major groups after reconstruction of a phylogenetic tree by Bayesian inference. The analysis showed that a portion of gC (approximately 671 bp) is under selective pressure at various points that coincide with regions of protein disorder. It was also possible to divide SuHV-1 into five genotypes that evolved under...

ABSTRACT: Pseudorabies (PR) is a highly contagious viral disease of great animal health and economic importance in swine industry. The aim of this study was to evaluate different genomic regions, real-time PCR chemistries and equipment for the molecular diagnosis of PR. Eight primer pairs targeting four genes (gB, gC, gE, gD), three different qPCR chemistries (SybrGreen, hydrolysis probes and plexor) and two equipment (ABI7500, Rotorgene 3000) were evaluated. Oligonucleotides targeting gB using hydrolysis probes showed the best performance after evaluating efficiency (99%), the detection limit (10-1.5 TCID50 mL-1) and diagnostic sensitivity and; therefore, those primers were selected for performance verification factors such as repeatability,...
