Abstract |
A milk and serum ELISA containing lipoarabinomanan ( LAM) antigen was evaluated in sheep and goats versus agar gel immunodiffusion (AGID) test and polymerase chain reaction (PCR) using milk and lymph nodes. Milk and serum samples were obtained from six, two, and four flocks with unknown, negative and positive status of infection, respectively. By comparison of serum ELISA activity and PCR results, the positive and negative predictive values were calculated. Receiver operation characteristic (ROC) analysis was used for calculating the specificity and sensitivity at different cut-offs.
