ACVPM EXAM QUESTIONS AND ANSWERS
100% CORRECT!!
, Concentrated Animal Feeding Unit (CAFO) - ANSWER USDA definition of CAFO:
Concentrated Animal Feeding Operation
intensive Animal Feeding Operation (AFO) in which over 1000 animal units are confined
for over 45 days a year.
Animal unit: equivalent to 1000 pounds of "live" animal weight.
A thousand animal units equates to:
1000 cows
700 cows used for dairy purposes
2500 pigs weighing more than 55 lbs
125,000 chickens
82,000 egg laying hens or pullets
Brevetoxin - ANSWER A group of similar neurotoxic compounds which are tasteless
and odorless. Although toxicity can result from inhalational, dermal, or oral exposure,
the most common route of exposure is by oral ingestion of contaminated shellfish.
Illness from oral ingestion is characterized by a combination of gastrointestinal and
neurologic signs and symptoms. Gastrointestinal symptoms include abdominal pain,
vomiting, and diarrhea. Neurologic signs and symptoms include paresthesias, reversal
of hot and cold temperature sensation, vertigo, and ataxia. Inhalational exposure may
cause respiratory symptoms such as cough, dyspnea and bronchospasm. This type of
toxin can also cause illness in aquatic wildlife.
domoic acid - ANSWER Potent neurotoxin produced by harmful algal blooms of marine
phytoplankton Pseudo-nitzschia.
Kainic acid-type neurotoxin (activates glutamate receptors) that causes amnesic
shellfish poisoning (ASP), produced by algae and accumulates in shellfish, sardines,
and anchovies.
acute hepatopancreatic necrosis disease (AHPND) - ANSWER whiteleg shrimp
Penaeus vannamei in Texas
pirA and pirB toxin genes identical to those detected in other AHPND-causing Vibrio
sp. / V. parahaemolyticus
Marburg virus - ANSWER Hemorrhagic filovirus endemic to central/south Africa,
reservoir is Egyptian fruit bat (rousettus aegyptiacus), humans often exposed within
caves.
