Usually, you will see *bowing of the long bones* with rounding of the skull in addition to the
clinical findings mentioned.
The disease usually occurs as a result of *secondary nutritional hyperparathyroidism*. When
there is inadequate calcium absorbed from the diet, the *parathyroid glands become hyperactive,
causing release of calcium stores in the bones*, leading to *fibrous and pliable* bones.
Adequate nutrition is key to preventing this disease!! - answer✔✔An 8-month old iguana
presents for further evaluation of a lack of thriving. On physical exam, a pliable mandible and
maxilla are palpated. What is your diagnosis?
a. Metabolic bone disease
b. Coccidioidmycosis
c. This is a normal finding
d. Osteomyelitits
The etiologic agent for *PBFD* is *circovirus-1* and *circovirus-2* so submitting a *whole
blood* sample for *DNA probe* analysis is the best method to check for *viremia*. -
answer✔✔You are presented with two young wild cockatoos that have immature, clubbed
feathers and a malformed beak (see image). You suspect this is Psittacine Beak and Feather
Disease (PBFD). Which test would you run to confirm your diagnosis?
b. A serologic test for antibody to herpesvirus
c. PCR probe of whole blood for polyomavirus DNA
d. A gram stain of the diseased feather pulp.
*Uterine adenocarcinoma* is the most common *neoplasia* of *female rabbits*, with up to
*80%* incidence among intact females of certain species.
Because of this, all female rabbits that are *not breeders* should be *spayed*. The most
common signs of uterine ACA are *hematuria, anorexia, depression, dysuria*, and *milk
production*.
Pregnancy would be unlikely to cause *hematuria*. Rabbits are *induced ovulators* and *do
not* exhibit estrous. Hematuria must be distinguished from *porphyrinuria*, which is a normal
*red or orange* pigment in the urine of some *rabbits*. However, porphyrinuria *DOES NOT*
cause *anorexia* and *weight loss*.
Rabbit syphilis is a *sexually* transmitted disease caused by *Treponema paraluis cuniculi*. It
causes *perineal lesions* but does not cause hematuria - answer✔✔A 5-year old female intact
New Zealand White rabbit presents for *hematuria, anorexia*, and *weight loss*. What is the
most likely differential?
a. Uterine adenocarcinoma
b. Normal Estrous
c. Rabbit syphilis
d. Porphyrinuria
e. Pregnancy
The correct answer is *vertebral fracture*.
Fractures in the *caudal lumbar* region frequently occur when rabbits *are not handled
properly* or are stimulated to jump around excessively.
*Fractures* are *much more common* than *luxations, disc extrusions*, or *emboli*.
The most common site of fracture is *L7*. - answer✔✔A client brings in her rabbit, which
acutely went down in the hind limbs after playing with the owner's daughter yesterday. On
physical exam, the rabbit is dribbling urine and has no withdrawal in the hind legs. Forelimbs are
normal. What do you suspect?
a. Hansen's type II disc herniation
b. Vertebral fracture
c. Fibrocartilage embolism
d. Vertebral luxation
e. Hansen's type I herniation
The correct answer is *renal adenocarcinoma*.
A *mass* in the renal parenchyma of a bird will compress and compromise the function of the
*ischiatic nerve*, causing a unilateral leg *lameness*.
We would be unlikely to see *unilateral lameness* with *lead toxicity*. Bumblefoot could affect
*one* foot, but *WOULD NOT* cause polydipsia.
Teflon toxicity causes *acute death* in *birds*. - answer✔✔An adult budgerigar presents sitting
on the floor of its cage. It has a history of polydipsia, weight loss, and progressive left leg
lameness. What is your highest suspicion for what may be causing these signs?
a. Renal adenocarcinoma
b. Bumble foot
c. Lead toxicity
d. Teflon toxicity
The correct answer is to *euthanize the colony*.
The disease is a *zoonotic* concern, so *euthanasia is recommended* for animals affected with
the disease. - answer✔✔You diagnose a colony of mice with lymphocytic choriomeningitis
(LCM). What is your next step?
a. Euthanize the colony
b. Treat aggressively with antibiotics
c. Do nothing; the disease is self limiting
d. Notify the federal authorities
The correct answer is *metabolic bone disease*. Other things to look for are a *pliable
mandible* and *maxilla*.
Usually, you will see *bowing* of the *long bones* with rounding of the *skull*. The disease
usually occurs as a result of *secondary nutritional hyperparathyroidism* or hypovitaminosis D.
*Gout* results from a *primary overproduction* of uric acid or an *inability* to *excrete uric
acid*. - answer✔✔A one year old rescued iguana presents for further evaluation as a result of
poor growth. Survey radiographs show osteopenia and evidence of remodeling suggestive of a
previous fracture. What is the most likely diagnosis?
a. Hypovitaminosis C
b. Primary Hypoparathyroidism
c. Gout
d. Metabolic bone disease
The correct answer is *ivermectin*.
