Fig. 1.

Comparison of rhinovirus clinical isolates phylogeny using Neighbor-joining method. A total of 117 reference sequences obtained from Genbank were used for alignment and 43 of them are shown in the figure. Genbank accession numbers are indicated. Isolates were assigned to genogroup to which they clustered in the phylogenetic tree with a significant bootstrap value >50% [21]. HRV genogroups are indicated in the right side of each branch. HRV-Ca belongs to genogroup C but genetic similarity in the 5′NCR region forces clustering with HRV-A [17], [21], [41], [42], [43].
