Table 2.

MIC distribution of S. suis isolates (n = 388).

^*The white area indicates the dilution range of the antimicrobials which were tested on the isolates. Green and red vertical lines indicate respectively the susceptible and resistant clinical breakpoints recommended by the CLSI(^C), EUCAST(^E), FDA(^F) and reported data(^RD).

^#MIC₅₀: The MIC that inhibits 50% of the tested isolates, MIC₉₀: The MIC that inhibits 90% of the tested isolates.

S: Susceptible percentage, I: Intermediate percentage, R: Resistant percentage.

^aLincospectin combination was tested in a concentration ratio of 1:2. MIC values in the table represent spectinomycin concentrations.

^bTrimethoprim/sulfamethoxazole combination was tested in a concentration ratio of 1:5. MIC values in the table represent sulfamethoxazole concentrations.
