FIG 4.
Nucleotide conservation status of two PRRSV coinfecting strains found in sample 2153073. Nucleotide identity between the two strains was found in sample 2153073. A full blue line indicates that both strains are identical in that given nucleotide position, and gray/white indicates that they differ at that position. The nucleotide identity between both PRRSV strains is 81.83%. The numbers on top of the blue bar indicate the nucleotide positions.
