Q Fever, or Coxiella burnetti is most frequently found in ruminates such as cattle, sheep and goats. Unfortunately it has also been found in wildlife and pets. Sheep are the most frequently infected, followed by goats and lastly cattle. Ticks carry the disease, but are of minor importance in the transmission of the disease to people and animals.
