Susceptibility to penicillin and rifampin by year-Brazil.

*Brazil tests a random selection of isolates (67% in this study). Calculations take into account the percentage of penicillin intermediate-resistance as on the previous year.

* 巴西对随机选取的分离菌株（isolates）开展检测，本研究中此类样本占比达67%。计算过程将上一年度的青霉素中介耐药性（penicillin intermediate-resistance）占比纳入考量范围。
