  • Cytauxzoonosis is an often-fatal disease caused by a tick-borne protozoan parasite, typically found in bobcats. It is more commonly seen in the southern United States but is spreading with tick migration. It can cause anorexia, lethargy, respiratory difficulty, anemia, and jaundice. Diagnostic testing, treatment options, and preventives are described in this handout. This disease is not transmissible to dogs or humans.

  • Discospondylitis is a bacterial or fungal infection of the intervertebral discs and the adjacent vertebral bones in the back. It primarily affects dogs, though rarely can affect cats. It affects large-breed dogs more often and generally starts as back pain. This handout outlines the diagnosis and treatment of this condition.

  • Distemper is a highly contagious viral disease of domestic dogs and other animals, such as ferrets, skunks, and raccoons. It is often fatal, and affects the respiratory, gastrointestinal, and central nervous systems. Vaccines are available and are highly effective at preventing disease.

  • Echinococcosis refers to being infected with a tapeworm of the genus Echinococcus and is primarily a parasite of coyotes and foxes. Infected cats are usually asymptomatic, but in both cats and humans the parasite can cause large cysts to form within the lungs and liver. E.multilocularis is treated with praziquantel and in most cases the prognosis is good.
