To study the evolution and virulence of pneumococcal populations, we used multilocus sequence typing to identify the major clones among 212 carriage and invasive isolates expressing capsular serogroup 6 from 39 countries. The global population consisted of 8 major complexes and 6 minor complexes of related clones and 32 clones of diverse origin. Surprisingly, serotype 6A clones evolved by mutation nearly as often as by recombination, whereas serotype 6B clones evolved almost exclusively by recom ...[more]
