A. Strep. agalactiae mastitis, retained placenta, laminitis
B. milk fever, malnutrition, excess dietary zinc
C. dystocia, overfeeding in dry period, Ca-P imbalance in feed
D. agalactia, milk fever, bovine vibriosis
E. contaminated calving environment, abortion, hypomagnesemia

- dystocia, overfeeding in dry period, Ca-P imbalance in feed
Cows are also predisposed to metritis by:
- retained placenta
- contaminated calving environment
- abortion
- malnutrition
In cattle, the causative bacterial organisms isolated most often are
Trueperella pyogenes alone or with Fusobacterium necrophorum or other
gram-negative anaerobes.
, Specific diseases associated with bovine metritis or endometritis include
brucellosis, leptospirosis, trichomoniasis, and bovine campylobacter.
Which one of the following sets of conditions predispose a cow to metritis?
A. contaminated calving environment, abortion, hypomagnesemia
B. agalactia, milk fever, bovine vibriosis
C. milk fever, malnutrition, excess dietary zinc
D. Strep agalactiae mastitis, retained placenta, laminitis
E. dystocia, overfeeding in dry period, Ca-P imbalance in feed

A 6-year-old hunter jumper horse is presented with a three-month history of poor
performance and intermittent shifting hindleg lameness.
There is reluctance to bring the hindlimbs forward at a trot and he occasionally drags
his hind toes
On physical exam, there is poor muscling of the gluteal muscles and some asymmetry
to the croup (rump). The horse shows pain and reluctance to ventroflex the back when
midline pressure is applied.
Which of the following is a top differential diagnosis?
,A. cauda equina (polyneuritis equi)
B. suspensory desmitis
C. overlapping vertebral spinous processes
D. sacroiliac disease
E. coxofemoral luxation

- sacroiliac disease
Think of sacroiliac disease in an athletic jumping horse with intermittent
hindlimb lameness localized in the croup, evidence of back pain, and
swelling over the tuber sacrale.
Coxofemoral luxation is rare in horses due to a deep acetabulum and the
presence of the accessory ligament of the hip, unique to horses
Overlapping vertebral spinous processes is a problem of thoracic and
lumbar vertebra under the saddle area, seen in short-backed eventing
horses
Cauda equina can cause gluteal muscle atrophy, but also causes tail
paralysis, urinary and fecal incontinence, perineal analgesia or paresthesia,
and mild hindlimb ataxia
Many hens in a large backyard flock recently became ill after the owner purchased
four new chickens. The sick hens are gasping, coughing, and sneezing. They have
poor appetite and act depressed. Some affected birds have watery green diarrhea
and swelling of the head and neck. A few have paralyzed legs and wings, twisted
necks, are circling, and have tremors or clonic spasms. Birds are not laying well and
some eggs are misshapen with watery albumen. Many of the sickest birds have died.
Necropsy of a dead chicken shows petechial hemorrhages on the mucosal surface of
the proventriculus and gizzard. What should be done next to address this problem?
A. treat all affected chickens with amprolium
B. disinfect housing with phenolic compounds, barrier precautions for staff
C. report outbreak to regulatory authorities
, D. increase poultry house temperatures to reduce morbidity
E. cull affected birds and vaccinate the remainder

- report outbreak to regulatory authorities
the history and necropsy findings are consistent with Newcastle disease,
which is reportable.
gross lesions such as the petechiae seen here in the proventricular mucosa
are not usually seen with low-virulence Newcastle disease
NDV occurs worldwide and chickens usually present with acute respiratory
disease. Occasionally diarrhea, neurological problems, or depression
predominate.
sometimes the temperature of the poultry house is increased to decrease
morbidity and mortality in flocks with suspected avian influenza
Amprolium is a treatment for coccidiosis
Which of the following is the correct location for placement of a proximal
paravertebral block used to perform a standing laparotomy in a cow?
A. caudal to the transverse processes of T13, L1, and L2
B. at the ends of the transverse processes of L1, L2, and L4
C. midway between spine and the ends of the transverse processes of L1, L2, and L3
D. in the spaces between L1, L2, L3, and L4
E. above and below the transverse processes of L1, L2, and L4
