Case Report: Atypical Cutaneous Manifestations of Tularemia after Horsefly Bite.

Tularemia is an infectious zoonosis caused by Francisella tularensis, an aerobic, noncapsulated, Gram-negative coccobacillus. It is more common in the northern hemisphere, and there are sporadic reports in non-endemic areas. The bacterium is usually transmitted by the bite or feces of a tick or other arthropods such as mosquitoes and horseflies. We report a case of an Italian patient with tularemia after a horsefly bite.
