DVM Trivia 4

Question 1

What is the most common cause of infectious tracheobronchitis ('kennel cough') in dogs?

Accepted Answer

Bordetella bronchiseptica

Answer

While kennel cough is often polymicrobial, Bordetella bronchiseptica is the primary bacterial pathogen and the basis for most kennel cough vaccines.

Question 2

Which condition in neonatal foals is characterized by failure to absorb colostral immunoglobulins and is diagnosed by measuring serum IgG?

Accepted Answer

Failure of passive transfer

Answer

Failure of passive transfer (FPT) occurs when foals do not absorb sufficient IgG from colostrum within 24 hours of birth, leaving them immunocompromised.

Question 3

A cat presents with anisocoria, Horner's syndrome, and ipsilateral forelimb lameness after a car accident. What structure is most likely damaged?

Accepted Answer

Brachial plexus

Answer

Avulsion of the brachial plexus disrupts sympathetic fibers traveling through the nerve roots (T1-T3), causing ipsilateral Horner's syndrome and forelimb paresis.

Question 4

What is the primary mode of transmission of rabies virus from an infected animal to a new host?

Accepted Answer

Bite wound inoculation of saliva

Answer

Rabies virus is transmitted almost exclusively through the bite of an infected animal, introducing virus-laden saliva into wound tissue where it infects peripheral nerve endings.

Question 5

Which electrolyte imbalance is classically associated with 'downer cow syndrome' after parturition?

Accepted Answer

Hypocalcemia

Answer

Parturient paresis (milk fever) results from acute hypocalcemia as calcium demand for colostrum and milk production exceeds mobilization capacity.
