Introduction. Streptococcus constellatus are opportunistic microorganisms. When immunocompromised patients with concomitant systemic diseases are infected with S.constellatus, the bacteria may cause sepsis. Case study. A patient was admitted to hospital due to septic shock and multi-organ dysfunction in the course of neck phlegmon. The microbiological system identified S. constellatus in the patient who worked as a dog groomer. These facts confirmed that this aetiological factor may have caused such a serious infection because S. constellatus is a bacterial species found in dogs. It is most likely that the bacteria colonised the patient. Zoonotic transmission of microorganisms is particularly important for the development of infections in dogs and humans. Knowledge about how to treat deep cervical infections is necessary in the daily practice of a maxillofacial surgeon. The right antibiotic can applied only when the strain causing the infection has been identified.
