a selective medium for Rothia mucilaginosa and its distribution in oral cavities
Journal of Microbiological Methods, 2012Co-Authors: Taira Kobayashi, Osamu Tsuzukibashi, Satoshi Uchibori, Haruhiko Goto, Masahiro AidaAbstract:Abstract A selective medium for Rothia mucilaginosa (RMSM) was developed to examine the population of R. mucilaginosa in oral cavities. The growth recovery of R. mucilaginosa on RMSM was 85.1% relative to HI medium. R. mucilaginosa was detected at 3.4% of total bacteria from stimulated saliva of 8 subjects.

a novel selective medium for the isolation and distribution of Rothia dentocariosa in oral cavities
Journal of Microbiological Methods, 2012Co-Authors: Satoshi Uchibori, Taira Kobayashi, Osamu Tsudukibashi, Haruhiko Goto, Masahiro AidaAbstract:Abstract Rothia dentocariosa is an indigenous microbial flora of dental plaque. To examine the bacterium population in oral cavities, a novel selective medium, designated RDSM, was developed for the isolation of R. dentocariosa. RDSM was prepared by adding 0.5 μg/ml of lincomycin, 10 μg/ml of colistin, and 40% sucrose to Heart Infusion (HI). Average growth recovery of R. dentocariosa on RDSM was 93.8% that of HI medium. Growth of other bacteria including Rothia mucilaginosa , Neisseria , Actinomyces , or streptococci was remarkably inhibited on the selective medium. Clinical efficacy was evaluated by the recovery of R. dentocariosa on RDSM from the stimulated saliva samples of 8 volunteers. R. dentocariosa was detected at 2.6 (range: 1.0–4.6) % to total bacteria of 8.0 × 10 7 CFU/ml on BHI in their oral cavities. The new selective medium, RDSM, was highly selective for R. dentocariosa and was useful for the isolation of R. dentocariosa from clinical samples.

Rothia mucilaginosa bacteremia a 10 year experience of a pediatric tertiary care cancer center
Pediatric Blood & Cancer, 2019Co-Authors: Fiona Poyer, Waltraud Friesenbichler, Caroline Hutter, Herbert Pichler, Michael Dworzak, Christina Peters, Georg Mann, Alexander IndraAbstract:: Rothia mucilaginosa is part of the oral and upper respiratory tract flora. Usually, this gram-positive coccus is not pathogenic; however, in the setting of immunosuppressed hosts, it can cause life-threatening infections as an opportunistic pathogen. Among a cohort of 1511 hematologic-oncologic patients at a pediatric tertiary care cancer center, we identified five cancer patients (0.35%) within a period of 10 years having a proven Rothia mucilaginosa bacteremia (1 culture positive: n = 3/5; > 1 culture positive: n = 2/5). With prompt and adequate antibiotic treatment, infection resolved rapidly before recovery of neutrophils and without any sequelae, suggesting that Rothia mucilaginosa bacteremia without organ involvement is not exceptionally problematic in pediatric cancer patients.

Rothia prosthetic knee joint infection report and mini review
new microbes and new infections, 2013Co-Authors: N Mahobia, P Chaudhary, Y KamatAbstract:Rothia spp. are gram-positive pleomorphic bacteria that are part of the normal oral microflora. They are associated with dental and periodontal disease, although systemic infections have also been reported. We describe the case of a 75-year-old lady with rheumatoid arthritis who presented with prosthetic knee joint infection due to Rothia aeria. We discuss its identification and the evidence regarding association of dental disease with Rothia spp. joint infections based on available literature.
