Comparison of microarray-predicted closest genomes to sequencing for poliovirus vaccine strain similarity and influenza A phylogeny.

We evaluate sequence data from the PathChip high-density hybridization array for epidemiological interpretation of detected pathogens. For influenza A, we derive similar relative outbreak clustering in phylogenetic trees from PathChip-derived compared to classical Sanger-derived sequences. For a positive polio detection, recent infection could be excluded based on vaccine strain similarity.
