Data include 15 new STs (ST3058, ST3894, ST3896, ST3897, ST3899, ST3900, ST3901, ST4419, ST3936, ST3937, ST3938, ST3939, ST3940, ST3941, and ST3942) assigned for the first time in this study.
ST17 (n = 1), ST20 (n = 1), ST58 (n = 3), ST155 (n = 3), ST162 (n = 9), ST224 (n = 3), ST297 (n = 9), ST602 (n = 2), ST1081 (n = 1), ST1196 (n = 2), ST3714 (n = 3), ST3939 (n = 1).
ST10 (n = 5), ST48 (n = 2), ST93 (n = 1), ST165 (n = 1), ST189 (n = 1), ST209 (n = 1), ST215 (n = 1), ST226 (n = 2), ST746 (n = 2), ST1638 (n = 2), ST1684 (n = 2), ST2913 (n = 1), ST3489 (n = 1), ST3896 (n = 1), ST3897 (n = 1), ST3899 (n = 1), ST3936 (n = 1), ST3937 (n = 1), ST3941 (n = 1), ST3942 (n = 2).
