I macrorestriction patterns in PFGE of 42
ST40 isolates. The phylogenetic analysis was generated with BioNumerics 6.0. The scale bar represents the level of similiarity in % using default settings (tolerance 1.0; optimization 0.5). The dotted vertical line at 82% similarity delineates the breakpoint for defining related fragment patterns/strains according to an international agreement. Certain sub-clusters indicated a comparably high level of clonal relatedness. Sequenced isolates are marked with a black square. Legend: H, human; A, animal; F, food; 1 reference strain; B, blood culture; CSF, cerebrospinal fluid; C, colonizer; E, endocarditis; F, food; M, bovine mastitis; PF, peritoneal fluid; U, urine; W, wound. Origin: D, Germany; DK, Denmark; PL, Poland; IS, Island; GR, Greece; ESP, Spain.
