Editor: Rothia dentocariosa is an aerobic or facultatively anaerobic, non spore forming, nonmotile, pleomorphic gram-positive rod. Although it is an inhabitant of the human oropharynx, R. dentocariosa has been mostly isolated from patients with endocarditis, arteriovenous fistulas, and pneumonia as an opportunistic pathogen (1). In this report we described the second known case of R. dentocariosa peritonitis in a continuous ambulatory peritoneal dialysis (CAPD) patient, the first being reported by Bibashi et al. in 1999 (2). A 50-year-old man with end-stage renal disease came to the emergency room with abdominal pain and mild fever. He began hemodialysis in 1993 and has now been on CAPD since 1998. Dialysate effluent was cloudy and WBC count was 2000/mm3. Predominance of neutrophils was observed on Gram stain but there were no micro-organisms identified. Two peritoneal dialysate samples (10 mL) were injected into Bactec 9210 (Becton Dickinson, MD, U.S.A.) blood culture bottles. Bacterial growth was determined on the second day via detection of CO2 production. Rough colonies were observed in subculture. On Gram stain, branched diphtheroid-like gram-positive cocco-bacilli were observed. These bacteria were tested by API Coryne strips (bioMerieux, Marcy l’Etoile, France). The result code (7050125) was not included in the routine API database. Differentiation of R. dentocariosa from CDC group 3, group A-3, group 5, and Actinomyces viscosus was performed by lysine and ornithine de...
