Clinical high-level beta-lactam-resistant isolates from Spain bore a novel plasmid, pB1000, expressing a functionally active ROB-1 beta-lactamase. Pulsed-field gel electrophoresis was applied for the first time to H. parasuis and showed that beta-lactam resistance is due to clonal spread of a resistant strain, BB1018, bearing pB1000. %~
