Veterinary Technician Practice Exam

Brucellosis is indeed the correct answer, as it is a zoonotic disease caused by the Brucella species, which can infect cattle and subsequently be transmitted to humans. This disease is known to cause undulant fever, a condition characterized by fluctuating fevers typically occurring in waves. In humans, brucellosis often results from consuming raw milk or unpasteurized dairy products from infected animals, as well as from direct contact with infected livestock or contaminated environments. While the other diseases listed do affect cattle, they either do not transmit to humans or do not cause the specific symptom of undulant fever associated with brucellosis. For instance, foot and mouth disease primarily affects livestock and is not zoonotic; mad cow disease is associated with bovine spongiform encephalopathy and leads to different neurological symptoms; and leptospirosis, although it can affect a variety of animals and humans, is caused by different bacteria and does not specifically lead to undulant fever. Thus, brucellosis stands out as the primary concern related to this question.
