Temocillin is used for several years in some European countries but, only since 2015 in France. We assessed the susceptibility of Enterobacterales strains isolated from blood culture 1 year before (2014) and 2 years after (2017) its use in France. 1,387 strains were included by 17 clinical laboratories located throughout France: 363 in 2014 and 1,024 in 2017. The rate of resistance to temocillin was 4.6% and 26.7% in 3rd generation cephalosporin (3GC) susceptible and resistant strains respectively. Cephalosporinase-overproducer (COPE) strains were significantly more resistant to temocillin (37.7%) than ESBL-producer (ESBL-PE) (23.5%) (P < 0.01). The rate of temocillin resistance was correlated to the number of inactive beta-lactams. The rate of resistance to temocillin trend to increase from 13.9% in 2014 to 23.9% in 2017 (P < 0.01). Temocillin remains highly active against Enterobacterales but the trend in resistance should be assessed over time.
替莫西林在一些欧洲国家已经使用了多年，但直到 2015 年才在法国使用。我们评估了替莫西林在法国使用前一年（2014 年）和使用后两年（2017 年）从血培养中分离的肠杆菌科菌株的敏感性。17 家临床实验室在法国各地共纳入了 1387 株菌株：2014 年 363 株，2017 年 1024 株。在第三代头孢菌素（3GC）敏感和耐药菌株中，替莫西林的耐药率分别为 4.6%和 26.7%。产头孢菌素酶（COPE）菌株对替莫西林的耐药率（37.7%）明显高于产超广谱β-内酰胺酶（ESBL-PE）菌株（23.5%）（P < 0.01）。替莫西林的耐药率与失活β-内酰胺的数量相关。2014 年至 2017 年，替莫西林耐药率从 13.9%上升至 23.9%（P < 0.01）。替莫西林对肠杆菌科仍具有高度活性，但耐药趋势应随时间进行评估。
