DNA (A) and amino acid (B) sequences of individual spa repeats and their letter codes based on variation from a DNA consensus sequence. Repeats were obtained by a GCG FINDPATTERNS search with the ambiguous search patterns AAAGAAGAXXXXAAXAAX {1,4} CCXXXX and GAGGAAGAXXXXAAXAAX {1,4} CCXXXX. Identical residues are identified by dashes, and gaps are identified by tildes.
