Figure 7.

Alignment of interrogated gyrA sequences with published reference sequences from all non-pestis Yersinia spp. strains tested (see Table 11). The Y. pestis reference sequence is shown at the top with primer sequences underlined. Mutations at the positions shown in red have been demonstrated to cause quinolone resistance [37,38]. Sequence substitutions predicted to cause a decrease in T_m are highlighted in yellow. Y. entero = Y. enterocolitica; Y. krist = Y. kristensenii; Y. pseudo = Y. pseudotuberculosis.
