UPDATE GRADED A+
1. What is the primary purpose of a surveillance system in veterinary public health?
A. To treat sick animals
B. To monitor disease trends

A. Rabies
B. Canine parvovirus
C. Feline leukemia
D. Equine influenza
Rationale: Rabies can be transmitted from animals to humans, making it zoonotic.
3. What does R0 (basic reproduction number) represent in epidemiology?
A. Rate of recovery
B. Number of deaths
C. Average number of secondary cases
D. Vaccine efficacy
Rationale: R0 indicates the average number of secondary infections produced by one
infected individual in a fully susceptible population.
4. Which sampling method ensures every member of a population has an equal chance
of being selected?
A. Convenience sampling
B. Random sampling
C. Stratified sampling
D. Purposive sampling
Rationale: Random sampling is designed to give each individual an equal probability
of selection.
5. Which foodborne pathogen is most commonly associated with poultry?
A. Salmonella
B. Listeria
C. E. coli O157:H7
D. Clostridium botulinum
Rationale: Salmonella is a common contaminant of poultry products.
,6. What is herd immunity?
A. Immunity achieved by vaccinating all individuals
B. Immunity only in sick animals
C. Immunity caused by antibiotics
D. Immunity in individual animals only
Rationale: Herd immunity occurs when a sufficient proportion of the population is
immune, indirectly protecting susceptible individuals.
7. Which of the following is a vector-borne disease?
A. Foot-and-mouth disease
B. Lyme disease
C. Bovine tuberculosis
D. Avian influenza
Rationale: Lyme disease is transmitted by ticks, which act as vectors.
8. What is the gold standard for diagnosing a viral infection?
A. Serology
B. PCR
C. Culture
D. Symptom observation
Rationale: PCR detects viral genetic material and is considered the most accurate
method for viral diagnosis.
9. Which disease is caused by a prion?
A. Bovine spongiform encephalopathy
B. Anthrax
C. Brucellosis
D. Canine distemper
Rationale: BSE is caused by misfolded prion proteins, not bacteria or viruses.
10. What is the incubation period?
A. Time from infection to appearance of symptoms
B. Time from treatment to recovery
C. Time from vaccination to immunity
D. Time from exposure to environmental contamination
Rationale: The incubation period is the time between exposure and symptom onset.
11. What is a sentinel animal used for in disease surveillance?
A. To serve as a breeding stock
B. To indicate presence of disease
C. To test vaccines
D. To produce antibodies
Rationale: Sentinel animals are monitored to detect early presence of disease in a
population.
,12. Which measure indicates the proportion of a population affected by a disease at a
specific time?
A. Incidence
B. Prevalence
C. Mortality rate
D. Attack rate
Rationale: Prevalence measures existing cases at a specific time.
13. Which of the following bacteria is Gram-positive?
A. Escherichia coli
B. Staphylococcus aureus
C. Salmonella
D. Pseudomonas
Rationale: Staphylococcus aureus is a Gram-positive bacterium.
14. What is a notifiable disease?
A. Any common disease
B. Disease required by law to be reported
C. Disease only affecting pets
D. Disease without public health significance
Rationale: Notifiable diseases must be reported to authorities to allow for control
measures.
15. Which of the following is a method of indirect disease transmission?
A. Direct contact
B. Aerosol
C. Fomite
D. Vertical transmission
Rationale: Fomites are inanimate objects that can carry infectious agents.
16. Which pathogen causes brucellosis in cattle?
A. Brucella abortus
B. Salmonella enterica
C. Bacillus anthracis
D. Leptospira interrogans
Rationale: Brucella abortus is the primary cause of brucellosis in cattle.
17. What is the main goal of biosecurity on a farm?
A. Increase milk production
B. Prevent disease introduction and spread
C. Reduce feed costs
D. Enhance reproduction
Rationale: Biosecurity measures aim to protect animals from infectious agents.
18. Which type of epidemiologic study observes outcomes without intervention?
A. Experimental
, B. Observational
C. Randomized controlled trial
D. Clinical trial
Rationale: Observational studies collect data without manipulating exposures.
19. Which virus is transmitted by mosquitoes?
A. Foot-and-mouth disease
B. West Nile virus
C. Bovine viral diarrhea
D. Canine adenovirus
Rationale: West Nile virus is spread via mosquito vectors.
20. Which of the following is a reportable foodborne illness in the U.S.?
A. Salmonellosis
B. Canine parvovirus
C. Equine rhinopneumonitis
D. Feline calicivirus
Rationale: Salmonellosis is tracked for public health monitoring.
21. What is the case fatality rate?
A. Proportion of deaths among all infected individuals
B. Proportion of infected among the population
C. Number of new cases per time unit
D. Number of recovered cases
Rationale: CFR quantifies mortality risk among diagnosed cases.
22. Which species is a common reservoir for rabies in the U.S.?
A. Dogs
B. Bats
C. Chickens
D. Pigs
Rationale: In the U.S., bats are the primary wildlife reservoir for rabies.
23. What is the purpose of a quarantine?
A. Treat sick animals
B. Isolate animals to prevent disease spread
C. Vaccinate animals
D. Breed animals
Rationale: Quarantine prevents potentially infected animals from spreading disease.
24. Which term describes a disease that is always present in a population?
A. Epidemic
B. Endemic
C. Pandemic
D. Sporadic
Rationale: Endemic diseases maintain a constant presence within a population.
