Tularemia in man is an acute infection characterized typically by the rapid onset of generalized symptoms and the coordinate development of a local ulcerative lesion at the site of a wound or insect bite. The disease is primarily a disease of rodents, in which it occurs as an epizootic disease. It is usually transmitted to man by wound contamination, from contact with an infected rabbit, or by the bite of an infective deer fly or wood tick. Of the seven cases of the infection reported in this paper, six occurred closely grouped geographically in a region in which the disease had not previously been reported. They represent the first cases of insect transmission occurring in Minnesota and demonstrate a possible source of the infection not previously described.
Tularemia, as a disease of ground squirrels, was first described in 1911 and 1912 by McCoy and Chapin,1 who isolated the causative
