Comparison of the clonal complex distribution of the study isolates and all English, Welsh and Northern Irish serogroup B invasive meningococcal disease isolates for the epidemiological year 2007/8.

<p>Isolates used in the study were selected to represent the diversity and distribution (in terms of clonal complex) of all English, Welsh and Northern Irish invasive MenB isolates from 2007/8. Note that a proportion of the predominant CCs (cc269 and cc41/44) were forfeited to include lesser CCs. Other variations were due to the limited availability of multilocus sequence typed isolates with accessible clinical specimens. UA = unassigned STs. n/a = not applicable.
