Rothia mucilaginosa, rarely isolated pathogen as an etiological factor of infection of soft tissues in young, healthy woman.

This paper presents a rare case of facial soft tissue infection caused by the bacterial strain of Rothia mucilaginosa. Odontogenic background of infection and initial clinical presentation suggested the presence of typical bacterial flora and uncomplicated course of treatment. However, despite surgical intervention and broad-spectrum antibiotic therapy, the expected improvement of a clinical status was not achieved. Only detailed bacteriological examination allowed to establish a bacterial pathogen and start a targeted antibiotic therapy. The unusual clinical course was monitored by imaging CT examination and further surgical interventions. A significant improvement was obtained in the third week of hospitalization and further antibiotic therapy was continued by means of outpatient treatment. Rothia mucilaginosa infection together with dental intervention is a rare case, since most of the reports in the literature concern the patients with decreased immunity. In such patients, the most common areas of infection were: the peritoneum, lung tissue and meningeal spaces of the brain and the presence of a foreign body.
