Multidrug-resistant strains of Shigella dysenteriae type 1 were implicated in three outbreaks and sporadic cases of dysentery in eastern India in 2002 and 2003. After a hiatus of 14 years, this pathogen reemerged with an altered antibiotic resistance pattern. In addition to ampicillin, co-trimoxazole, tetracycline, chloramphenicol, and nalidixic acid, all the recent strains were resistant to norfloxacin, lomefloxacin, pefloxacin, and ofloxacin and showed reduced susceptibility to ciprofloxacin. Pulsed-field gel electrophoresis identified a new clone of S. dysenteriae type 1 that was associated with the recent outbreaks and sporadic cases. Based on the spatial and temporal spread of multidrug-resistant S. dysenteriae type 1, we predict that this clonal type may spread further in this region.
2002年和2003年,多重耐药的1型志贺氏痢疾杆菌株与印度东部的三起痢疾暴发及散发病例有关。在中断了14年后,这种病原体以改变的抗生素耐药模式再次出现。除了氨苄青霉素、复方新诺明、四环素、氯霉素和萘啶酸外,所有近期菌株对诺氟沙星、洛美沙星、培氟沙星和氧氟沙星均耐药,且对环丙沙星的敏感性降低。脉冲场凝胶电泳鉴定出一种与近期暴发和散发病例相关的1型志贺氏痢疾杆菌新克隆。基于多重耐药1型志贺氏痢疾杆菌的时空传播情况,我们预测这种克隆类型可能会在该地区进一步传播。
