showed clinical signs of lethargy, lameness, and labored breathing before dying.
Postmortem examination of an affected pig shows severe fibrinous pleuritis, pericarditis,
and peritonitis. Which of the following is the most likely causal organism?
Arcanobacterium suis

Salmonella cholerasuis
Streptococcus suis - correct answer. Haemophilus parasuis
A 9-week-old Rottweiler-mix puppy is beign evaluated because of an itchy rash around
the lips and eyelids. Temperature is 103.3*F. Physical examination shows swellign of
the muzzle, pruritic, exudative pustiles around the lips and eyelids, and swelling of the
submandibular lymph nodes bilaterally. Which of the following is the most appropriate
treatment?

A 5-year old Simmental cow who is used as a donor for embryo transfer is evaluated
because of the acute onset of anorexia and lethargy. She has been flushed six times;
the most recent flushing occured 10 days ago. Rectal temperature is 104*F . During PE,
the cow is reluctant to move and periodically kicks at her abdomen. On rectal palpation,
the left kidney is grossly enlarged and has a smooth texture. When stimulated to
urinate, the urine is grossly hematuric; numerous blood clots and fibrin are present.
Which of the following is the most appropriate treatment?
Administration of gentamicin intravenously
Administration of procaine penicillin G intramuscularly
Long-term catheterization of the bladder
Surgical removal of the enlarged kidney
No treatment is indicated - correct answer. Administration of procaine penicillin G
intramuscularly
In a mare, a 30-day pregnancy is most likely to be detected on rectal examination by
which of the following?
Absence of ovarian follicles
Palpation of the chorionic vesicle
Palpation of the corpus luteum
Palpation of the fetus
Slipping the fetal membranes - correct answer. Palpation of the chorionic vesicle
a 12-year old male budgerigar is evaluated because of a two-week history of
progressive difficulty gripping with the right foot. The client reports that during the past
three days, the bird has stopped using the foot entirely but he still flies around the house
daily. On physical examination, mild coelomic distention is palpated. The bird is
standing on his perch using the left leg only. All toes of the right food are pointing
downward with no gripping capability. Which of the following is the most likely cause of
the paralysis?
Chronic heavy metal toxicity
Previous trauma
Renal neoplasm
Right-sided intervertebral disk disease
Severe arthritis - correct answer. Renal neoplasm
