Phylogenetic analysis based on concatenated sequences of seven housekeeping genes (gki, gtr, murI, mutS, recP, xpt, and atoB) showing the position of the 15 bovine SDSD isolates and sequences of strains available in the National Center for Biotechnology Information (NCBI) database, including SDSD strains (n = 12), SDSE strains (n = 15), Streptococcus pyogenes strains (n = 11), Streptococcus canis strains (n = 3). VSD, Vet S. dysgalactiae subsp. dysgalactiae. Bovine SDSD isolates: ATCC 27957; NCTC13731; NCTC4669; NCTC4670 and VSDs. Human SDSD strains: DB31752-13; DB49998-05; DB60705-15, and DB53993-17. Fish SDSD strain: SDSD Kdys0611. SDSE, S. dysgalactiae subsp. equisimilis. The phylogenetic relationships were inferred using the minimum evolution method, and phylogenetic distances were estimated using the maximum composite likelihood method using the MEGA (Kumar et al., 2018). The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree.
