[Tularemia: A case report].

Background. - Tularaemia is a zoonotic disease caused by inoculation with the Gram-negative coccobacillus Francisella tularensis. It was first described in the United States in 1911 and is a rare disease with an annual reported incidence in France between 2002 and 2012 of 0.07 cases per 100,000 habitants. Reporting of the disease in humans has been mandatory in France since 2003. Patients and methods. - Herein we report a case of tularaemia following a tick bite in a patient in the north of France. Discussion. - Tularaemia is a rare form of zoonosis that should be sought in the event of unexplained adenitis. Clinical presentations vary, and in certain cases only dermatological signs are manifest. Diagnosis is confirmed by bacterial serology. Rapid initiation of suitable antibiotics produces a favourable and benign outcome in most cases. However, the offending organism, which is potentially lethal, is classed as a potential bioterrorism agent. (C) 2018 Elsevier Masson SAS. All rights reserved.
