Origin of samples are shown, with the code on the left (for positions of these codes relating to United Kingdom geography, see Fig. 1 and 2) and percent prevalence (no. sampled/no. testing positive). Sequence types found more than once are indicated across the top (and correspond to those on the tree in Fig. 1 and 2). Sequence types found only once are also shown, as are the total number of sequences from an area and the proportion of these which are 2a. The numbers and origins of samples of non-PDSA origin are indicated, as are the total numbers of sequences per sequence type. The number of hospitals where a sequence type was isolated is also shown. Sequence types which showed significant evidence of clustering in certain areas are indicated with an *, though numbers were small (see text). Origin of non-PDSA samples: HP, Hartlepool; CW, Crewe; LV, Liverpool; StH, St. Helens; BL, Blyth; WO, Worcester; CA, Cambridge; BA, Barrow; BP, Blackpool; SH, Shrewsbury.
