Reconstruction of dispersal patterns of hypervirulent meningococcal strains of serogroup C:cc11 by phylogenomic time trees [PDF]

, 2019
Neisseria meningitidis is one of the few commensal bacteria that can even cause large epidemics of invasive meningococcal disease (IMD). N. meningitis serogroup C belonging to the hypervirulent clonal complex 11 (cc11) represents an important public ...
