| detection of two porcine circovirus type 2 genotypic groups in united states swine herds. | in late 2005, sporadic cases of an acute onset disease of high mortality were observed in 10- to 16-week-old growing pigs among several swine herds of the united states. tissues from the affected pigs in kansas, iowa, and north carolina were examined, and porcine circovirus type 2 (pcv2) was detected consistently among these tissues. phylogenetically, pcv2 can be divided into two major genotypic groups, pcv2-group 1 and pcv2-group 2. whereas pcv2-group 1 isolates were detected in all the disease ... | 2007 | 17219018 |
| effect of a major quantitative trait locus for porcine reproductive and respiratory syndrome (prrs) resistance on response to coinfection with prrs virus and porcine circovirus type 2b (pcv2b) in commercial pigs, with or without prior vaccination for prrs. | a major qtl for host response to porcine reproductive and respiratory syndrome (prrs) virus (prrsv) infection was identified in a previous study. single nucleotide polymorphism wur10000125 (wur), which is in complete linkage disequilibrium with the putative causative mutation, can be used as a tag snp for the qtl. however, the effect of wur following prrs vaccination and/or coinfection with other pathogens is not known. therefore, objectives of this study were to estimate the effect of wur on ho ... | 2017 | 28380604 |
