The Regional Resistance Surveillance program monitored susceptibility rates and developing resistance by geographic region, including 12 Asia-Pacific (APAC) countries. Reference broth microdilution methods for susceptibility/interpretations were applied, processing 5,053 strains. Among Staphylococcus aureus isolates (37% methicillin-resistant S. aureus [MRSA], highest in South Korea [73%]), linezolid (LZD), tigecycline (TIG), and vancomycin were 100% active, but 33 and 34% of strains were levofloxacin (LEV) or macrolide resistant, respectively. Streptococcus pneumoniae was most resistant to β-lactams and macrolides (45%) but was LZD, LEV, and TIG susceptible (>98%). Extended-spectrum β-lactamase (ESBL) phenotype rates in Escherichia coli and Klebsiella spp. were 48 and 47%, respectively, and were highest in Taiwan, at 75 to 91%. The best anti-ESBL-phenotype agents were amikacin (81 to 96% susceptible), colistin (COL; >98%), TIG (>98%), and carbapenems (81 to 97%). Pseudomonas aeruginosa showed ≥20% resistance to all drugs except COL (99% susceptible). In conclusion, endemic evolving antimicrobial resistances in APAC nations show compromised roles for many commonly used antimicrobials.
区域性耐药监测计划监测了地理区域的耐药率和耐药发展情况,包括亚太地区 12 个国家。应用了参考肉汤微量稀释法进行药敏/解释,共处理了 5053 株菌株。在金黄色葡萄球菌分离株中(37%耐甲氧西林金黄色葡萄球菌[MRSA],韩国最高[73%]),利奈唑胺(LZD)、替加环素(TIG)和万古霉素的活性均为 100%,但分别有 33%和 34%的菌株对左氧氟沙星(LEV)或大环内酯类耐药。肺炎链球菌对β-内酰胺类和大环内酯类(45%)最耐药,但对 LZD、LEV 和 TIG 敏感(>98%)。大肠埃希菌和克雷伯菌属的产超广谱β-内酰胺酶(ESBL)表型率分别为 48%和 47%,在台湾最高,为 75%至 91%。针对 ESBL 表型的最佳抗生素为阿米卡星(81%至 96%敏感)、黏菌素(COL;>98%)、TIG(>98%)和碳青霉烯类(81%至 97%)。除 COL(99%敏感)外,铜绿假单胞菌对所有药物的耐药率均≥20%。总之,亚太国家的流行的抗菌药物耐药性正在不断演变,许多常用抗菌药物的作用受到影响。
