简介：
Overview
This article presents a rapid RT-LAMP assay for detecting Tilapia lake virus (TiLV) in tilapia fish, offering a quicker alternative to conventional RT-PCR methods. The protocol aims to assist in controlling the spread of TiLV, particularly in developing countries where tilapia is a vital protein source.
