Figure 2From: Widespread acquisition of antimicrobial resistance among Campylobacter isolates from UK retail poultry and evidence for clonal expansion of resistant lineagesClonalFrame genealogies of Campylobacter isolates from UK retail poultry surveys in 2001 and 2004 – 5. Grey-scale shading indicates the percentage of isolates in each ST with antimicrobial resistance to (A) tetracycline, (B) quinolones - naladixic acid & ciprofloxacin combined, (C) erythromycin, (D) chloramphenicol, (E) aminoglycosides. The scale bar indicates the genetic distance in coalescent units.Back to article page
