✍️ Sample DVM Questions & Answers
1. Prolonged diestrus (persistent corpus luteum) in mares is characterized by:
Persistent CL in mares occurs when normal PGF2α-mediated luteolysis fails, often following early embryonic death, resulting in persistently elevated progesterone and behavioral anestrus.
2. A swine herd shows signs of sneezing, nasal discharge, and facial deformity in young pigs. Which pathogen is the primary cause of atrophic rhinitis?
Toxigenic strains of Pasteurella multocida produce a dermonecrotic toxin causing turbinate atrophy and facial deformity in progressive atrophic rhinitis.
3. A dog has a prolonged APTT with a normal PT. Which coagulation factor deficiency is most consistent with this pattern?
Factor VIII is part of the intrinsic pathway (measured by APTT only), so its deficiency prolongs APTT while PT remains normal.
4. A caprine blood smear shows Heinz bodies on new methylene blue stain. Which toxin is most commonly responsible in goats?
Copper toxicity in small ruminants causes oxidative damage to hemoglobin, forming Heinz bodies and leading to intravascular hemolytic crisis.
5. In the context of biosecurity, what does 'biocontainment' specifically refer to?
Biocontainment refers to measures that prevent pathogens already present within a facility from spreading to other animals, farms, or regions.
6. Which epidemiological measure describes the probability that an animal without disease will develop disease during a specific time period?
Cumulative incidence (risk) is the proportion of disease-free animals that develop disease during a defined time period, expressed as a probability.
