Skin involvement in Francisella tularensis infection: a case report of two clinical cases.

Tularemia, or rabbit fever, is a zoonotic infection caused by Francisella tularensis, a Gram-negative coccobacillus. F. tularensis subsp. holarctica (type B) is the predominant form in Slovenia. Humans become infected through arthropod bites, direct contact with an infected animal, ingestion of contaminated water or food, and inhalation of contaminated aerosol. The most common form is ulceroglandular tularemia (> 80%), which is characterized by a skin ulcer and regional lymphadenopathy. Below we present two cases of tularemia with skin involvement.
