We report extensively drug-resistant (XDR) Shigella sonnei infection in an immunocompromised patient in Texas, USA. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry failed to identify XDR Shigella, but whole-genome sequencing accurately characterized the strain. First-line antimicrobials are not effective against emerging XDR Shigella. Fosfomycin, carbapenems, and tigecycline are potential alternatives.
我们报道了美国德克萨斯州 1 例免疫功能低下患者的广泛耐药(XDR)宋内志贺菌感染。基质辅助激光解吸/电离飞行时间质谱未能鉴定出 XDR 宋内志贺菌,但全基因组测序准确地对该菌株进行了特征描述。针对新兴的 XDR 宋内志贺菌,一线抗菌药物无效。磷霉素、碳青霉烯类和替加环素是潜在的替代品。
