ABSTRACT
Rothia mucilaginosa, previously known as Stomatococcus mucilaginosus, is a Gram-positive coccus that is part of the oropharyngeal microbiota and upper respiratory tract. It is mainly related to infections in immunosuppressed patients. Given its complex microbiological identification, its prevalence may be underestimated. We describe in this article a case of bacteraemia by Rothia in an immunocompetent paediatric patient without epidemiological or medical relevant history. In the available literature no cases of bacteraemia by Rothia mucilaginosa in immunocompetent paediatric patients have been reported. Given the characteristics of our patient, the publication of this case is of interest. Once the diagnosis of Rothia mucilaginosa has been made, the correct functioning of the immune system of the patient should be checked.
