Figure. Neighbor-joining phylogenetic tree of human rhinoviruses (HRV) isolated from 4 respiratory disease outbreaks with associated deaths in long-term care facilities, Ontario, Canada. Tree was constructed by using a 549-bp nt region encoding viral capsid protein (VP) 4/VP2, along with strains representative of HRV species A, B, and C. Echo 11 is the outgroup. Bootstrap analysis used 1,000 pseudoreplicate datasets. Scale bar represents 0.1% of nucleotide changes between close relatives. Boldface indicates sequences deposited in GenBank.
