“…Core genome and/or traditional MLST-derived phylogeny is highly congruent with WGS and/or SNP-derived phylogenies, and avoids the need to reconstruct computationally heavy phylogenies ( Jolley et al., 2018 ; Patiño et al., 2018 ; Versteeg et al., 2018a ; Jelocnik et al., 2019 ; Floridia-Yapur et al., 2021 ). Chlamydial MLST was effectively used in uncovering the global epidemiology of C. trachomatis strains ( Herrmann et al., 2015 ; Danielewski et al., 2017 ), identifying clonal psittacine, horse and human strains of C. psittaci during an outbreak ( Anstey et al., 2021 ) as well closely related but genetically diverse avian chlamydial strains ( Figure 5A ), distinguishing diverse koala C. pecorum strains to aid in translocation of animals ( Figure 5B ) ( Fernandez et al., 2019 ) and other examples ( Batteiger et al., 2014 ).…”
