More than 100 serotypes of HRV are known, which have been classified into two species, HRV-A and HRV-B, according to comparative alignment of nucleotide fragments of VP1 [11, 12] , VP4/VP2 [13] and 59UTR [14, 15] , and more recently, on complete genome nucleotide sequences [16] . Moreover, some genomic sequences have been found not to cluster with HRV-A and HRV-B species, which suggests the existence of other species (HRV-C and HRV-D) [16] . A new species of HRV-C was recently identified worldwide by comparative analysis of VP4 or VP4/VP2 genes [7, 17, 18, 19, 20, 21] and 59UTR [14, 15] .
