Bacteroides pyogenes can cause infections in humans. We describe a case of bloodstream infection caused by Bacteroides denticanum that probably originated from a dog bite. MALDI-TOF MS misidentified this new species as B. pyogenes. Subsequent analysis using the 16S rRNA sequencing approach identified the species as B. denticanum.
化脓性拟杆菌可导致人类感染。我们描述了一例可能由犬咬伤引起的齿龈拟杆菌血流感染病例。基质辅助激光解吸电离飞行时间质谱（MALDI-TOF MS）将这个新物种误鉴定为化脓性拟杆菌。随后使用16S rRNA测序方法分析确定该物种为齿龈拟杆菌。
