Fig. 1From: Imported arboviral infections in Italy, July 2014-October 2015: a National Reference Laboratory reportNeighbour-Joining phlylogenetic analysis of sequences obtained from DENV positive samples using Tamura-Nei model with 1000 bootstrap reiterations. For each sequence, GenBank accession number/viral genotype/country of origin of the infection/year of the infection are reported. Sequences characterized in this study are indicated by a black square. The bars indicate the percentage of diversity. Bootstrap values over 80% obtained from 1000 replicate trees are shown for key nodes. a: DENV-1 genotypes; b: DENV-2 genotypes; c: DENV-3 genotypes; d: DENV-4 genotypesBack to article page
