Anti-Brucella antibody production in response to B. melitensis 16M following infection. The standard tube agglutination test was used to measure anti-Brucella antibodies in serum collected at different time points post-infection for both the short-term (closed squares) and long-term (open circles) infection groups. Data points reflect the average of the optical values across each set of goats, ± the standard error of the mean
