Rothia dentocariosa is a commensal organism of the human oropharynx. Clinical infection due to this organism is rare. A case of recurrent peritoneal dialysis-related peritonitis caused by R dentocariosa and a review of the literature is reported. Isolation of R dentocariosa from dialysate fluid should not be dismissed as a contaminant. Although there are no interpretive criteria for antimicrobial susceptibility testing, R dentocariosa appears to be susceptible to a variety of antibiotics including beta-lactams, vancomycin and aminoglycosides. Optimal therapy of peritoneal dialysis peritonitis caused by this organism may also require removal of the catheter.
齿垢密螺旋体是人类口咽部的共生菌。由该菌引起的临床感染较为罕见。本文报道了一例由齿垢密螺旋体引起的复发性腹膜透析相关性腹膜炎,并进行了文献复习。从透析液中分离出牙垢密螺旋体不应被视为污染物而忽视。虽然目前尚无抗生素药敏试验的解释标准,但齿垢密螺旋体似乎对包括β-内酰胺类、万古霉素和氨基糖苷类在内的多种抗生素敏感。治疗该菌引起的腹膜透析相关性腹膜炎的最佳方法可能还需要拔管。
