<p>Percentage of antimicrobial resistance among <i>Escherichia coli</i> isolates.</p

Antibacterial resistance patterns of <i>Escherichia coli</i> isolates.

<p><b>A.</b> Percentages of <i>E</i>. <i>coli</i> isolates from chickens, pigs, cows and ducks were resistant to 0–2, 3–5, 6–8, 9–11 and 12–18 antibacterial drugs, respectively. While 78.7% (48/61) of cow isolates showed resistance to 0–2 drugs, the pig isolates showed similar resistances to 3–5 drug (27.4%, 31/113), 6–8 drugs (23.0%, 26/113), and 9–11 drugs (24.8%, 28/113). In ducks, most isolates were resistant to 6–8 drugs (61.4%, 27/44) and 9–11 drugs (31.8%, 14/44). The worst bacterial resistance was seen in chickens, and 71.6% of the isolates were resistant to more than 6 antibacterial drugs (6–8 drugs: 26.2%, 169/664; 10–12 drugs: 26.2%, 169/644; 12–18 drugs: 15.7%, 101/644.</p
