Rabbit Tularemia and Hepatic Coccidiosis in Wild Rabbit

摘要

To the Editor: Tularemia is a highly pathogenic zoonosis caused by the gram-negative intracellular bacterium Francisella tularensis. F. tularensis causes serious septicemia in animals, especially wild rodents and lagomorphs (rabbits and hares), and potentially fatal, multisystemic disease in humans. The human mortality rate can reach 30% in untreated persons (1). F. tularensis is listed as a category A bioterrorism agent by the Centers for Disease Control and Prevention alongside the causative agents of anthrax, plague, smallpox, botulism, and viral hemorrhagic fevers. Generally, lesions associated with septicemic tularemia include multifocal 1–2-mm, white foci of necrosis in the liver, spleen, lymph nodes, and lungs.
