Francisella tularensis bacteraemia causing multi-organ failure.

Tularemia is a zoonosis caused by the gram-negative coccobacillus . The bacterium can be transmitted in several ways including direct contact with animal reservoirs, ingestion, inhalation and bites, and typical clinical symptoms are headache, fever, diarrhea and dyspnea. has two predominant subspecies (ssp), namely ssp. and ssp. . Ssp. is less virulent and does usually not cause fatal disease. We here present a 51-year-old male with sepsis and multi-organ failure caused by ssp. infection suggesting that atypical agents including should be considered in patients presenting symptoms of infections without response to standard treatments.
