Several imipenem-susceptible and -resistant Aeromonas veronii biovar sobria isolates with different morphologies and antimicrobial susceptibilities recovered from bile samples of a patient with cholangitis were analysed. These isolates belonged to the same clone and the imipenem-resistant strains showed overexpression of the imiS gene, encoding a chromosomal carbapenemase. These results should make clinicians aware of the possible emergence of multidrug-resistant A. veronii biovar sobria, perhaps as a consequence of previous treatment of a urinary tract infection with amoxicillin plus clavulanic acid.
对从一名胆管炎患者胆汁样本中分离出的几株形态和药敏性不同的对亚胺培南敏感和耐药的维罗纳气单胞菌温和生物变种菌株进行了分析。这些分离株属于同一克隆，耐亚胺培南菌株显示编码染色体碳青霉烯酶的imiS基因过表达。这些结果应使临床医生意识到多重耐药维罗纳气单胞菌温和生物变种可能出现，这可能是先前用阿莫西林加克拉维酸治疗尿路感染的结果。
