Francisella tularensis is the bacterium responsible for a lethal plague-like illness in humans and animals known as tularemia. It has been responsible for large epidemics in Europe and Asia, and causes epizootic illnesses elsewhere in the world. The utility of F. tularensis as a biological weapon was studied extensively by during World War II, and the microorganism may have used in that conflict for that purpose. During the Cold War F. tularensis was studied for its potential as a biological weapon. Various scenarios have been developed by international health organizations to assess the health and economic impacts of a biological attack using F. tularensis. F. tularensis is now considered a category A biological agent by the Centres for Disease Control and Prevention (CDC). Journal of Bacteriology & Parasitology publishes original research articles, novel, and scientifically sound findings dealing with Bacteria and Parasites of Medical relevance to human or veterinary health, as well as those with application in Environmental or Food Sciences related to microbiology.
