15. This non-human primate arrived at your facility 30 days ago, and is currently being quarantined. An intradermal old mammalian tuberculin test was grade 0 at 6 days post-arrival, then again two weeks later. A final TB test was performed, and the results are shown below. Based on this photograph, what is the best clinical course of action?
a. Release the monkey from quarantine, as he is grade 0 again.
b. Repeat the intradermal TB test in 7 days, using the opposite eyelid, as this is a grade 4 reaction. Extend the quarantine period and include an alternative secondary test.
c. Repeat the intradermal TB test in 7 days, using the same eyelid, as this is a grade 4 reaction. Extend the quarantine period and include an alternative secondary test.
d. This is a grade 5 reaction; the animal should be euthanized.
e. Use an alternative TB test in 14 days, and take chest radiographs while the animal is sedated.
Answer: b. Repeat the intradermal TB test in 7 days, using the opposite eyelid, as this is a grade 4 reaction. Extend the quarantine period and include an alternative secondary test.
