“…Since then, only 3 other cases of R. dentocariosa endocarditis have been reported. [7][8][9] In these 23 patients, underlying heart conditions predominated as the predisposing risk factor: only 2 of the 23 had no known prior heart conditions. Seven had no concomitant risk factors-usually identified as dental in origin (for example, dental caries or recent oral procedures).…”

Rothia dentocariosa is a rare gram-positive bacterial organism, one of the group of microbes that normally resides in the mouth and respiratory tract. R. dentocariosa rarely causes disease. Documented cases occur chiefly in patients with valvular or dental disease, or both. We report the case of a previously healthy 58-year-old man who presented with evidence of bacterial endocarditis caused by this organism—which originated from an elusive source. His endocarditis was successfully treated with mitral valve replacement and the administration of antibiotic agents.

Peritonitis is well recognized as the Achilles tendon of peritoneal dialysis (PD). Reoccurrence of peritonitis due to the same organism, defined as either repeat or relapsing peritonitis under the 2005 guidelines by the International Society for Peritoneal Dialysis, often results in PD technique failure. Rothia dentocariosa, a low-virulent human oropharynx commensal, is a rarely reported pathogen in human infection, particularly infective endocarditis. R. dentocariosa PD-related peritonitis is exceedingly uncommon yet potentially results in repeat or relapsing peritonitis which requires catheter removal. We report a case of R. dentocariosa repeat and relapsing peritonitis in a PD patient who was treated successfully with antimicrobial therapy.

“…Boudewijns et al [8] reviewed all cases reported in the literature up to 2002. Since then, only two other cases of endocarditis [9,10], five cases of bacteremia without endocarditis [11][12][13] and two cases of sepsis [5,14] have been reported. In the 20 cases reviewed by Boudewijns et al [8], underlying heart conditions predominated as the predisposing risk factor.…”

Rothia dentocariosa endocarditis with mitral valve prolapse: case report and brief review

et al. 2011

We present a case of endocarditis with a rare pathogen, Rothia dentocariosa, in a patient with mitral valve prolapse. The symptoms began 1 month after the patient underwent cholecystectomy. Endocarditis was successfully treated with outpatient parenteral therapy with ceftriaxone, and follow-up blood cultures remained negative.Case report A 37-year-old man presented to our centre with a complaint of fever of 38.8°C for 1 month, occurring twice a day without antipyretics and associated with chills and drenching sweats. There was no associated cough, nausea, pain or rash. He had been prescribed oral amoxicillin-clavulanate 625 mg three times a day by his general practitioner which had relieved his symptoms, but the fever returned when the antibiotic was discontinued. Physical examination was unremarkable, except for an apical pansystolic murmur. His past medical history was insignificant except a laparoscopic cholecystectomy after an episode of acute cholecystitis 2 months prior to presentation. Preoperative work-up had revealed a pansystolic murmur with cardiomegaly (cardiothoracic ratio of 14.5: 24.5), and transoesophageal echocardiogram had shown moderate mitral regurgitation with ruptured posteriomedial chordae and flail middle scallop of posterior mitral leaflet consistent with mitral valve prolapse.The patient was a mechanical engineer by profession and a resident of Lahore, Pakistan. He travelled extensively to Dubai, Italy and the UK on business. He was a smoker (8 pack-years) and a social drinker. He had been married for 11 years with two children; however, he currently had multiple heterosexual partners.The patient was admitted to our centre for investigation of fever of unknown origin. The results of the routine outpatient workup for fever, including tests for malaria, dengue and urinalysis, were negative, and the results of baseline laboratory tests carried out at our hospital (including blood counts and renal and liver function tests) were all normal. Brucella antibody and the autoimmune (antidouble-stranded DNA, antinuclear antibodies) workup were also normal. Three blood samples, each taken 2 h apart, were sent for culture on the first day of admission, and the first culture turned positive after 72 h for branching Grampositive bacilli. These were initially thought to be contaminants; however, within the next 12 h the other two culture sets also turned positive for the same organism.The patient was initially started on only intravenous vancomycin 1 g twice daily. However, based on our experience of infections with 'branching' Gram-positive bacilli, we supplemented the vancomycin with intravenous penicillin-G at a dosage of 2 million Units four times daily. The Gram-positive bacilli were identified as R. dentocariosa by the API Coryne system (bioMérieux, Marcy l'Etoile, France; code no. 7050125; excellent identification; % id 99.9%; T = 1.00). The same organism also grew from the patient's bone marrow culture. The patient was diagnosed as having R. dentocariosa endocarditis, as he fulfilled one major c...
