Phylogenetic tree of Streptococcus iniae (SK − KM209199) and S. agalactiae (K10 − KM209200; P20− KM209201) from the present study (*) and other Streptococcus spp. based on 16S rRNA gene sequences. Neighbor-joining tree was constructed using MEGA 6 maximum composite likelihood method and 1000 bootstrap number with complete deletion. Percentages ≥50% are shown at the internal nodes. Bacillus subtilis was used as an outgroup.
