Figure 1From: Analysis of the genetic diversity and mRNA expression level in porcine reproductive and respiratory syndrome virus vaccinated pigs that developed short or long viremias after challengePhylogenetic trees. (A) NJ tree based on the 3813 bp of the CD163 analysed, corresponding to the exons 7–11 of the gene; (B) NJ tree based on the 641 bp of the SLA-1*04. Only bootstrap values higher than 65 were shown. Sequence labels include the pig identifier, the allele and the days of viremia.Back to article page
