Figure 2. Allele-based clusters of penicillin-nonsusceptible meningococcal isolates identified by using Neisseria meningitidis core-genome multilocus sequence typing (MLST) v1.0 scheme, Shanghai, China, 1965–2020. Arrows indicated the 3 singleton isolates identified by 7-locus–based MLST but assigned to CC4821 cluster by core-genome MLST analysis. Scale bar indicates numbers of loci. CC, clonal complex; IMD, invasive meningococcal disease; NG, nongroupable; NmB, serogroup B; NmC, serogroup C; NmW, serogroup W; NmY, serogroup Y; ST, sequence type.
