ESCALANTE YANGUELA, B. de et al. Bilateral bronchopneumonia due to Rothia mucilaginosa. Anales Sis San Navarra [online]. 2017, vol.40, n.3, pp.479-483. ISSN 1137-6627.  https://dx.doi.org/10.23938/assn.0090.

Rothia mucilaginosa (R. mucilaginosa), formerly named Stomatococcus mucilaginosus, is a facultatively anaerobic, encapsulated gram-positive coccus, which forms part of the normal oropharyngeal and is rarely considered to be a pathogen in immunocompetent patients, although it can produce, on rare occasions, serious infections like bacteremia, endocarditis and respiratory infections; such as pneumonia, pleural empyema or superinfection of bronchiectasis.

We present the case of a 74-year-old male diagnosed with right basal pneumonia of torpid evolution with poor initial response to different antibiotics, with clinical and radiological worsening and the appearance of bilateral bronchopneumonia with pseudonodular images. R. mucilaginosa in pure culture was isolated in three sputum cultures and in bronchial suction. The patient was finally treated with Linezolid with good clinical response and normalisation of the thorax radiography, confirming the disappearance of R. mucilaginosa in subsequent sputum cultures.

As there are few documented cases of pneumonia due to R. mucilaginosa, we believe that presenting this case will be of interest.
