From: Laboratory testing and phylogenetic analysis during a mumps outbreak in Ontario, Canada
Small hydrophobic (SH) gene sequencing phylogenetic tree. The SH phylogenetic tree was constructed based on the 316 nucleotides of the entire SH gene of four genotype G mumps outbreak isolates from Ontario (GenBank accession numbers: KY680537.1, KY680538.1, KY680539.1 and KY680540.1), three sporadic Ontario isolates (GenBank accession numbers: KY006856.1, KY006857.1 and KY006858.1) and representatives of other genotypes available in NCBI’s GenBank sequence database. The phylogenetic tree containing 37 strains was reconstructed using the Neighbor-Joining method and Maximum Composite Likelihood was used to compute the evolutionary distances. The statistical significance of the phylogenies constructed was estimated by bootstrap analysis of 1000 pseudo-replicate data sets (bootstrap values of > 70% are given at each node). The horizontal length of the bar denotes the nucleotide changes per site (MEGA version 6.06 software package). Outbreak and non-outbreaks isolates identified at Public Health Ontario Laboratory in 2010 are labelled with red and blue circles respectively
