The complete data set is given as Additional File 1.
+,- indicates each form comprises at least 10% of the group, but occurs only once in each genome.
+/- indicates at least 10% of the genomes in the group contain both forms. This cut-off removes all minor cases of HGT. nd indicates that the r-protein was not detected.
