Tilapia lake virus (TiLV) causes an emerging viral disease associated with high mortality and economic damage in tilapia farming around the world. The use of probiotics in aquaculture has been suggested as an alternative to antibiotics and drugs to reduce the negative impact of bacterial and viral infections. In this study developed by researchers at the Kasetsart University and the Michigan State University the effect of probiotic Bacillus spp. supplementation on mortality, viral load, and expression of immune-related genes in red hybrid tilapia (Oreochromis spp.) are investigated upon TiLV infection. This is a summarized version of the article which highlights some of the results obtained. USD 11 billion. Although tilapia can adapt, and tolerates variable farming conditions, recent outbreaks of emerging bacterial and viral diseases pose severe threats to the global tilapia aquaculture production. Recently, the outbreak of a new viral
disease, caused by tilapia lake virus (TiLV), has drawn attention due to the rapidity of it spreading between farms and countries. TiLV was identified as a singlestranded, negative-sense RNA virus sharing some characteristics with FEBRUARY - MARCH 2021
