Role of Rhinovirus C in Apparently Life-Threatening Events in Infants, Spain
Figure. Phylogenetic analysis of 5′ noncoding region and viral protein (VP) 4/2 coding region of 9 human rhinoviruses (HRVs) identified in infants with apparently life-threatening events in Spain, November 2004–December 2008. Phylogeny of nucleotide sequences (≈492 bp) was reconstructed with neighbor-joining analysis by applying a Jukes-Cantor model; scale bar indicates nucleotide substitutions per site. Included for reference are sequences belonging to the novel genotype reported previously (QPM and 024, 025, 026 ) and all HRV-A and -B serotypes available in GenBank. Significant bootstrapping is indicated.
