Phylogenetic analysis of partial sequences of the hexon gene (560 nucleotides) of adenovirus type 3 and type 7 collected in Cameroon from 2011 to 2014. The nucleotide sequences were aligned using the Clustal W method. The tree topology was built according to the maximum-likelihood method under the Tamura-Nei substitution model with the site heterogeneity gamma and invariant sites using the MEGA software 6. The scale bars represent the frequency of nucleotide substitutions. The accuracy of the tree was assessed by 1000 bootstrap replicates. Only Bootstrap values> 70% are presented. Cameroonian sequences are indicated by black triangles (▲) and the other sequences are the prototypes of 54 HAdV formally recognized by the ICTV. Cameroonian samples are identified in the following format: CMR (Cameroon), the year of detection and the laboratory number. The number of identical Cameroonian sequences is indicated in parenthesis following the name of the strain. Genbank accession numbers of all sequences used are shown in the tree. The scale bar represents the number of nucleotide substitutions per site between close relatives
