الإجابة: C. Brucellosis
A dairy-farm worker (with affected colleagues) with prolonged fever, weight loss, low back pain (spondylitis) and hepatomegaly has brucellosis - transmitted by raw dairy products/animal contact, with osteoarticular involvement causing low back pain and possible liver enzyme rise. PUO is a label, not a diagnosis; the exposure history makes TB and viral hepatitis less likely.

C
ليش صح
Brucellosis is spread by cattle, sheep, goats and pigs, and patients often work with animals, which fits a dairy-farm worker whose colleagues are also ill.

ليش غلط
PUO is a label for persistent fever with no diagnosis after the initial work-up. Here the dairy exposure with sick colleagues points to a specific diagnosis, brucellosis.
