  1. 1 CLSI class: means resistance to one third-generation cephalosporin or one quinolone
  2. 2 CLSI classes: means resistance to two third-generation cephalosporin or two quinolones, or one third-generation cephalosporin and one quinolone
  3. 3 CLSI classes: means resistance to one third-generation cephalosporin and two quinolones, or one third-generation cephalosporin and two quinolones
  4. 4 CLSI classes: means resistance to two third-generation cephalosporins and two quinolones
