It was not until 1911, however, that the causative organism was first isolated by McCoy and Chapin,2who were investigating a disease of ground squirrels in Tulare county, California. The organism was named Bacillus tularense after the county where it was first discovered. Fourteen years later one of Martin's patients was found to have a positive agglutination test for tularemia.1In 1913 Vail3saw an unusual form of conjunctivitis and Wherry and Lamb,4working on this case, were the first to isolate Bacterium tularense in pure culture from a human being.
