The assay demonstrated high sensitivity and specificity across 156 bacterial isolates obtained from various cultured fish species and geographical locations between 2008 and 2024, as well as against a panel of non\u2010target bacteria. It also successfully detected target pathogens in 146 field tissue samples, including tissues preserved in 70% ethanol, formalin\u2010fixed paraffin\u2010embedded (FFPE) tissues and tissues fixed on FTA cards. Compared to classical bacteriology, the multiplex qPCR assay yielded higher detection rates and enabled precise identification of the causative species of piscine lactococcosis. Overall, the multiplex qPCR assay developed in this study provides a reliable, rapid, highly sensitive and species\u2010specific molecular approach for diagnosing piscine lactococcosis, contributing to better surveillance and management of the disease in aquaculture.\n
