The species Corynebacterium pyruviciproducens was described in 2010 based on the features of a single strain. In this report, we describe the chemotaxonomic and phenotypic characteristics of 11 C. pyruviciproducens clinical strains isolated in Switzerland and Canada in comparison to the strain 06-17730(T). Heterogeneities within the type strain were found in the 16S rRNA gene and in biochemical markers. Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) identification of this species could not be achieved since currently this bacterial species is not included in the corresponding database. Reliable identification is obtained only with sequence-based identification tools. Results of antimicrobial susceptibility testing of this species with an extended panel of antimicrobials are presented here for the first time.
丙酮酸棒状杆菌是2010年根据单一菌株的特征描述的。在本报告中,我们描述了与06-17730(T)菌株相比,在瑞士和加拿大分离出的11株丙酮酸棒状杆菌临床菌株的化学分类和表型特征。在16S rRNA基因和生化标记中发现了模式菌株内的异质性。由于目前该细菌物种未包含在相应数据库中,因此无法通过基质辅助激光解吸电离飞行时间质谱(MALDI-TOF MS)鉴定该物种。只有使用基于序列的鉴定工具才能获得可靠的鉴定结果。本文首次展示了该物种对多种抗菌药物的药敏试验结果。
