Figure 1From: Clinical isolates of Yersinia enterocolitica Biotype 1A represent two phylogenetic lineages with differing pathogenicity-related propertiesMaximum likelihood tree based on the MLST of seven house-keeping genes of Y. enterocolitica strains. Color-coding indicates the BAPS groups. The BT 1A strains were divided into two clusters indicated in blue (Genetic group 1) and yellow (Genetic group 2). Strains of BT’s 2–4 are indicated in red and the BT 1B strain in green.Back to article page
