Isolation of the causative agent of tularemia from an inoculum from skin lesions in the ulcerobubonic form of the disease

A case of tularemia in a human patient infected through the sting of a gadfly (Tabanus) is described. The causative agent of the disease was isolated from the patient with the ulcerobubonic form of the disease by the method of the direct inoculation of the contents of the patient's cutaneous effect. The properties of the isolated culture were established; the strain thus obtained was classified as a representative of the geographical race Francisella tularensis holarctica 01s. The causative agent circulating in the human patients was found to be fully virulent.
