[A treacherous pet].

A 63-year-old woman presented with a 5-day history of high-grade fever, petechiae on the lower legs and severe thrombocytopenia. Clinical findings included left inguinal lymphadenopathy and an encrusted wound on the left tibia, which the patient had sustained from a rotten piece of wood. Her pet dog had sporadically licked the wound. After more than 2 days of blood culture incubation, Capnocytophaga canimorsus was finally detected. Antibiotic treatment with amoxicillin/clavulanic acid led to a complete recovery.
