Fig. 2From: Genomic analysis of nontypeable pneumococci causing invasive pneumococcal disease in South Africa, 2003–2013Maximum likelihood phylogenetic tree based on core genome SNPs of invasive nontypeable Streptococcus pneumoniae (n = 39), shown in red and yellow from South Africa (2003–2013). Encapsulated S. pneumoniae (representative of predicted ancestral serotypes) from South Africa (n = 42, shown in blue) and publically available nonencapsulated S. pneumoniae genomes ([20, 21] (n = 6, indicated green) were included for comparisonBack to article page
