Prophages identified among streptococcal genomes. a Average prophage content within each streptococcal species. SD, standard deviation. b Graphical representation of all prophages by average genome size and number of genes. Each prophage is coloured to represent its average guanine (G) and cytosine (C) content. c Satellite prophage SpnSP24 was represented among pneumococci isolated between 1939 and 2006 and all of these satellite prophage sequences were nearly identical at the nucleotide level. d An unrooted phylogenetic tree of all streptococcal prophage genomes identified in the data set. Blue branches mark full-length prophages and red branches mark satellite prophages. e Venn diagram depicting the number of genes found exclusively in full-length prophages or in satellite prophages (at a threshold of >70% amino-acid sequence similarity) and those genes that are shared.
