VP1 sequence identities and seroresponse correlations between tested polyomaviruses.

<p>The lower-left triangle shows homology (percentage sequence identity; 1 corresponds to 100% identity) between VP1 protein sequences of the six polyomaviruses tested generated by ClustalW alignment using Geneious Pro 5.6.3 software with default settings. For this alignment the following RefSeq/GenBank accession numbers were used: MCPyV, NC_010227; HPyV6, NC_014406; HPyV7, NC_014407; TSPyV, NC_014361; HPyV9, NC_015150; BKPyV, NC_001538. The upper-right triangle shows cross-reactivity between seroresponses measured against VP1 of the six polyomaviruses tested. For this analysis the serologic data from the complete study population were used (n = 799). Pearson correlation coefficients (r²) were determined by SPSS 20 software (IBM).
