Question 3

CAR bacillus in rat

Answer 3

gram negative bacterium that causes severe bronchiectasis, pulmonary abscesses, and atelectasis. It is found with Mycoplasma pulmonis when respiratory signs are evident in rats. It is not known if it can cause disease on its own.

Question 4

Cheyletiella parasitovorax

Answer 4

rabbit fur mite and causes white flakes that resemble dandruff along dorsum

Question 5

Cilia-associated respiraoty (CAR) bacillus infection in rats

Answer 5

associated with Mycoplasma pulmonis

Question 6

Corynebacteria kutschemi

Answer 6

Pseudotuberculosis in rats (dyspnea, oculonasal discharge, rough hair coat, and hunched posture, usually subclinical), pneumonia in rats Impression smear shows the characteristics “Chinese character” formation. Culture of the bacteria or serology can diagnose the infection as well.

Question 7

Daily water requirement for a rabbit

Answer 7

120 ml/kg

Question 8

Dietary recommendations for a ferret

Answer 8

The diet should be low in fiber and carbohydrates. Ferrets are strict carnivores that depend on meat proteins and fats. They need a highly digestible diet due to their short GI transit time. They lack intestinal flora to break down complex carbohydrates and diets rich in carbohydrates will lead to protein or fat malnutrition. Ferrets also cannot tolerate large amounts of fiber. High levels of plant proteins are associated with urolithiasis. Ferrets should not be fasted for longer than 6 hours as they irritable; additionally, if they develop insulinomas (which are not uncommon), periods without food can result in severe, fatal hypoglycemia. A high-quality dry kitten food or commercial ferret diet is appropriate.

Question 9

Encephalitozoan cuniculi

Answer 9

rabbit microsporidian parasite that causes neurologic and renal disease. The parasite directly infects the lenses of rabbits and causes phacoclastic cataracts and uveitis. Lens removal is the treatment required and steroids for the uveitis.

Question 10

Ferret adrenal gland tumor treatment

Answer 10

Surgical removal

normal cortisol levels

Question 11

Francisella tularensis

Answer 11

Causative agent of Tularemia, rabbit natural host and most commonly associated with zoonotic spread to humans.

Question 12

Hamster lifespan

Answer 12

approximately 2 years

Question 13

Insulinoma treatment in ferret

Answer 13

Medical management: prednisone and diazoxide alone or in combination. Dietary management with a high protein and low carbohydrate diet. Surgical removal of the tumor is also an option in otherwise healthy ferrets.

Question 14

Lymphocytic choriomeningitis in mice

Answer 14

euthanize entire coloney

Question 15

Answer 18

Lawsonians, and intracellular bacteria. Treat with antibiotics, very susceptible to chloramphenicol

Question 19

Psoroptes cuniculi

Answer 19

rabbit ear mite; causes severe crusting and inflammation of the external ear canals. Treatment is Ivermectin or selamectin.

Question 20

Required to Chinchilla health

Answer 20

dust baths: every 1-2 days in order to maintain coat health. The dust bath should not be left in the enclosure at all time since frequent bathing may cause conjunctivitis. Chinchillas are heat-intolerant, keep enclosure above 80 F. Avoid cedar bedding as it can cause respiratory irritation.

Question 21

Rotaviral infection in mice

Answer 21

Clinical signs: diarrhea with obstipation, affects young mice 1-3 weeks of age. Soft yellow feces that stain and dry around the anus, causing obstipation and death. Diagnosis based on clinical signs. Electron microscopy can be used for virus identification. Only treatment is to clean and remove impacted feces.

Question 22

Sendai virus in mice

Answer 22

a negative sense, single-stranded RNA virus of the family Paramyxoviridae

highly transmissible respiratory tract infection in mice, hamsters, guinea pigs, rats, and occasionally pigs, and marmosets[3]with infection passing through both air and direct contact routes. The virus can be detected in mouse colonies worldwide, generally in suckling to young adult mice. Epizootic infections of mice are usually associated with a high mortality rate, while enzootic disease patterns suggest that the virus is latent and can be cleared over the course of a year

Question 23

Transmissible Murine Colonic Hyperplasia in mice

Answer 23

mice 2-4 weeks of age, Citrobacter freundii stain 4280 gram negative enteric bacterium. Clinical signs: anorexia, dehydration, and diarrhea. Histopath shows thickening and inflammation of colonic mucosa. Adults show no signs. The disease is highly contagious but self-limiting. Treatment includes neomycin or tetracyclines

Question 24

Answer 24

causative agent of rabbit syphilis

Question 25
