Anaplasmosis (Anaplasma marginale)
Anaplasmosis is an infectious parasitic disease of cattle, sheep, and goats caused by the microorganism Anaplasma marginale. This parasite infects the red blood cells and causes severe anemia, weakness, fever, lack of appetite, depression, constipation, decreased milk production, jaundice, abortion, and sometimes death. The incubation time for the disease is typically around 21-45 days. Adult cattle are more susceptible to infection than calves.
Anthrax (Bacillus anthracis)
Scrapie is a neurodegenerative disease, caused by a prion, that affects sheep and occasionally goats. The last case of scrapie in North Dakota was identified in 2007.
Seneca Valley Virus (SVV) was recently diagnosed in pigs in the United States. The virus has also been found in South America, Australia, New Zealand, and Europe. The virus is a non-enveloped single-stranded RNA virus of the family Picronaviradae. Foot and Mouth Disease Virus (FMDV) and swine vesicular disease virus are also a member of this same viral family.
Tularemia (Francisella tularensis)
Tularemia is caused by the bacterium Francisella tularensis. It is a disease that affects animals and humans. Rabbits, hares, and rodents are especially susceptible to the disease but it can affect a variety of mammals. Tularemia can be found throughout the United States. The bacteria can be spread by bites of fleas, ticks, and other arthropods.
