Distribution over time of pneumococci with reduced susceptibility to penicillin (PRSP), penicillin-resistant pneumococci (PRP), and high-level penicillin resistant pneumococci (HLPRP). (A) Distribution among 355 S. pneumoniae isolates recovered from asymptomatic carriers. (B) Distribution among 428 S. pneumoniae isolates recovered from patients with IPD. Isolates showing penicillin MICs ≥ 0.12 < 2 μg/ml were classified as PRSP, those with MICs ≥ 2 < 4 μg/ml were classified as PRP and those with MIC ≥ 4 μg/ml were classified as HLPRP.
