^*PBAB numbers according to the Bacteriophage Bank of Korea (www.phagebank.or.kr).

^**The numbers in each box shows the maximum concentration of each antibiotic to which tested bacteria was resistant (mg/L).

Darkly shaded box means “resistant”, lightly shaded box “intermediate”, and white box “susceptible”.
