Tularemia ia an infectious disease produced by Francisella tularensis. The disease is primarily one of wild mammals, perpetuated in nature by ectoparasites, contaminated environment, cannibalism, and chronic carriers. It gives rise to a wide range of clinical manifestations in man depending on the route of the infection, the virulence of the strain, and the dose. The organism can be readily isolated from mud and water in some endemic areas. Natural infections have been reported in over 100 species of wild and domestic mammals, 25 species of birds, and 70 species of bloodsucking arthropods (Yow, 1981). Human infection is incidental, and human-to-human transmission is rare. The organism is highly infectious for man with as few as 10 viable organisms needed to produce infection (Saslaw et al., 1961). The organism can infect man through inhalation and ingestion, but the primary route is through the skin.
