Median-joining network inferred from stamp gene sequences of CPs strains detected in this study and of strains previously identified and published (Aryan et al. 2014; Atanasova et al. 2015; Cvrković et al. 2014; Fabre et al. 2011; Johannesen et al. 2012; Kosovac et al. 2016) (Table 2 and Additional file 2: Table S2). Genotypes are represented by circles and each SNP mutation is represented by a hatch mark. Circle sizes are proportional to strain frequency found in this study and host association(s) of genotypes is represented by different colour(s) of circles as shown in the figure legend. Grey circles represent reference strains not detected in this study while black dots represent median vectors. Network of a total of 22 stamp genotypes is presented. Genotypes were designated following established nomenclature (SEE-ERANET nomenclature), including designation of and newly identified genotype detected in this study (ST59)
