Tularemia: a case transmitted from a sheep.
Tularemia is an arthropod-borne infectious disease caused by Francisella tularensis, a gram-negative microorganism that normally resides in a wide range of wild and domestic animals. The disease is characterized by a sudden onset with high fever, headache, malaise, chills, myalgia, and arthralgia. A short time after exposure, an inflamed and ulcerated lesion rapidly appears at the site of entry. A regional lymphadenopathy follows the cutaneous presentation. Cultures from the lesions or blood generally give negative results. Histopathologic examination reveals either a nonspecific inflammatory infiltrate or an infectious granuloma. The most useful laboratory procedure in the diagnosis of tularemia is serologic tests. Streptomycin, gentamicin, and tetracycline are the drugs of choice in the treatment. Quinolones are also effective. Tularemia is fairly rare in Turkey. We present a typical case of ulceroglandular tularemia transmitted from a sheep to a young man.
