Figure: Penicillin (A) and tetracycline (B) MICs in isolates with susceptibility-associated genotypes, global and validation datasets.
Dashed lines indicate Clinical & Laboratory Standards Institute breakpoints for susceptibility and resistance. (A) Penicillin MICs of isolates with penA_101 and without blaTEM (susceptible genotype) compared with isolates with one or more of these determinants (non-susceptible genotypes). (B) Tetracycline MICs of isolates with wildtype rpsJ (57V) and without tetM (susceptible genotype) compared with isolates with one or more of these determinants (non-susceptible genotypes). MIC=minimum inhibitory concentration.
