Pan-genome size of NC S. pneumoniae isolates: (A) Proportions of gene coding sequences in the pan-genome divided into 4 categories: the hard-core and the soft-core genome, representing respectively 99% and 95% to 99% of genes shared between isolates. The shell genes are present in 15% to 95% of isolates, whereas the cloud genes are distributed in less than 15% of isolates.29,30,49 (B) Cumulative number of genes in the pan-genome. Box plots indicate first and third quartiles with medians shown as horizontal lines.
