Distribution of phylogroups (A, B1, B2, D) and non-typeables (NT).

<p>A: <i>E</i>. <i>coli</i> isolates originating from meat of locally reared chickens (n = 36), meat from imported chickens (n = 73) and cloaca of locally reared live chickens (n = 44). B: Distribution of antimicrobial frequencies in <i>E</i>. <i>coli</i> meat isolates (n = 109) into multiresistant isolates (≥3 antimicrobial drug classes), isolates resistant to 1–2 antimicrobial drug classes and fully susceptible isolates divided into phylogroups (A, B1, D) and non-typeable (NT). The B2 phylogroup was not included, as only one isolate, being multiresistant, belonged to this group.
