- a ssrS is annotated as an rRNA in Crooks but in K-12 and W it is annotated as an ncRNA. It is included in this table as an ncRNA
- The total number of genes, tRNA, other ncRNAs and IS elements in each strain includes pseudogenes/pseudo-tRNAs etc.; the number of pseudo-elements in each case is in noted in brackets. A '+' means the element is present; a '-' means the element is absent. ND = not determined in annotation. Safe laboratory strains: W (ATCC 9637) and its plasmids pRK1 and pRK2; K-12 (MG1655); B (REL606); and Crooks (ATCC 8739). W is in phylogroup B1; K-12, B and Crooks are in phylogroup A.
