◉ Which one of the following choices is the best initial treatment in
the patient with a moderate elevation of calcium caused by
idiopathic feline hypercalcemia?
A - Injectable fluids
B - Prednisolone
C - Diet change
D - Bisphosphonates
E - Furosemide
Answer: C
Diet changes such as a high fiber food or food designed to treat renal
disease may be effective in restoring normocalcemia in the feline
patient with Idiopathic hypercalcemia.
Prednisolone, fluid therapy, furosemide may be used in more
severely affected patients and when dietary therapy is ineffective.
,Bisphosphonates may be utilized if increased osteoclastic activity is
present.
◉ Feline leukemia (FeLV) status has been shown to affect many
aspects of disease progression and treatment of lymphoma.
FeLV seropositive cats with lymphoma are similar to FeLV
seronegative cats with lymphoma in which one of the following
aspects?
A - Remission rates
B - Treatment response
C - Survival time
D - Prevalence of gastrointestinal lymphoma
E - Prevalence of mediastinal lymphoma
Answer: B
Feline leukemia virus seropositive and seronegative cats share
similar response rates to initial treatment with chemotherapy for
lymphoma.
Lymphoma remission rates are higher and survival times are shorter
for cats with FeLV compared with FeLV negative cats.
,Most U.S. cats with mediastinal, multicentric, or spinal forms of
lymphoma are FeLV-positive.
◉ This calf was aborted at 7.5 months pregnancy in early fall. The
dam was a primiparous beef animal housed on pasture in Northern
California.
Necropsy revealed multiple petechial hemorrhages on the palate
and scleral mucus membranes of the fetus, and marked
lymphadenopathy. The calf was not decomposed; the cow retained
the placenta.

Which one of the following choices is the most likely diagnosis of the
abortion in this case?
A - Leptospira pomona
B - Brucella abortus
C - Neospora caninun
D - Pine needles
E - Foothill abortion agent
Answer: E
, This is a typical case of foothill abortion, also called epizootic bovine
abortion. The condition is common in the coastal and Sierra Nevada
foothills, and throughout much of the western United States. It is the
most common cause of abortion in California beef cattle.
The etiologic agent has not been identified with certainty. Research
suggests that it is a delta protobacteria with DNA homology to
bacteria of the vibrio genus. Pregnant cattle exposed to thymic
tissues from aborted fetuses can be protected from abortion by
feeding tetracycline through the early stages of pregnancy.
The agent is transmitted by the soft shelled Pajahuello tick
(Ornithodorus coriaceus). The disease occurs predominantly in
heifers. Infection develops during the first trimester of pregnancy
while abortions occur later around the 5th to 9th month.
Exposed cattle develop immunity, but it is not known how long
protection lasts. However, abortion does not often recur in these
animals. The presence of petechial hemorrhages and
lymphadenopathy in a late-term aborted fetus is suggestive of
foothill abortion.
Neospora is another common abortifacient of beef cattle, but does
not produce lymhadenopathy or petechiae in the fetus.
Leptospirosis, brucellosis, and pine needles also do not produce the
same pathologic lesions as the foothill agent.
