Stepwise sequential evolution of multidrug resistance in Campylobacter jejuni ST5136, Scotland. Red dots indicates resistance to antimicrobial drug as a result of genetic change or acquisition of resistance gene; white dot with red outline indicates acquisition of oxacillinase. Resistances are indicated as follows: aac3, aminoglycoside; C257T gyrA, fluoroquinolone; blaOXA-61–like, β-lactam (variant in ST5136 is OXA-193); tet(O/32/O), tetracycline. CC, clonal complex; OXA, oxacillin; R, resistant; ST, sequence type.
