الإجابة: E. Serology for brucellosis
Prolonged fever, weight loss, headache and myalgia in a goat-farm worker = brucellosis (zoonosis from goats, sheep, cattle). With a negative initial work-up including blood culture, the key test is brucella serology (serum agglutination), the initial diagnostic test. Malaria film, LP and HIV testing do not fit the exposure.
