Fig. 1.

Graphic representation of minimum spanning tree (MST) resulting from MLST typing of the 34 types registered with the international Mycoplasma agalactiae MLST Database (https://pubmlst.org/bigsdb?db=pubmlst_magalactiae_seqdef) as of January 2019. An identification policy based on recognition of all taxa with zero inter-taxon distance plus the priority rule using the Maximum number of N-locus variants (N=1) were employed in generation of the MST. Here each MLST type is represented only once. MLST types differing by a single MLST locus are shown by thick short lines while longer thin connecting two MLVA types denote types while those with larger differing loci are denoted by thin longer dashed or dotted lines. The MLST type of the three Iranian and PG2 Ma vaccine and laboratory strains are marked.
