Sequence data indicated that the divergence among isolates ranged from 0 to 5.7\u200a% at the nucleotide level and from 0 to 3.4\u200a% at the amino acid level. Phylogenetic analysis revealed four main clusters. A close correspondence between viral strains and area\/year of isolation could not be demonstrated, whilst co-circulation of different viral strains in the same area and in the same time period was observed for both patients and environmental viral isolates. Alignment of the deduced amino acid sequences and evolutionary analysis indicated that most of the sites along the gene may be invariable because of purifying and\/or neutral selection.<\/jats:p>","DOI":"10.1099\/vir.0.82330-0","type":"journal-article","created":{"date-parts":[[2007,3,20]],"date-time":"2007-03-20T19:23:13Z","timestamp":1174418593000},"page":"1288-1294","source":"Crossref","is-referenced-by-count":17,"title":["Genetic
