*) The higher number of CDS for the O:3/4 pYV plasmid compared to O:8/1B is evoked by more transposase-like CDS (including also remnant or fragmented transposases) and more than 20 hypothetical CDS with no strong similarity on protein level to serobiotype O:8/1B. In addition, we found an arsABRH gene cluster present in the pYV plasmid of serobiotypes O:3/4 and O:9/2, but not in O:8/1B.
