ABSTRACT Mexican goat production systems face infection risks from Brucella melitensis,small ruminant lentivirus (SRLv) and Mycobacterium avium subsp.paratuberculosis (MAP); agents that cause great economic losses anddirectly affect public health (brucellosis and paratuberculosis PTb). Currently, there are no diagnostic tests applicable at large scale nor epidemiological information regarding the seroprevalence for these infectious diseases. For this study, a multiplex antibody assay (Luminex®) was used to retrospectively study the seroprevalence of brucellosis,SRLv, and PTb in the sera of 983 goats from nine Mexican states. Sera were obtained between 2014 and 2019. Antibodies against all three infectious diseases were detected in almost all tested samples.The estimated seroprevalence values ranged from 37% to 78% for brucellosis, 21% to 65% for SRLv, and 0% to 13% for PTb.The multiplex assay (Luminex®) is a simple, accessible, efficient, and cost-effective seroprevalence monitoring tool for brucellosis,SRLv, and PTb, and can be used as a large-scale approach.
