Pathogenicity of causing mass mortalities of yellow catfish () and its induced host immune response.

The outbreak of mass mortality occurred in farm in Hubei province of China. The pathogenic strain of (termed 2022SI08) was isolated and identified from diseased , based on morphological, physiological, and biochemical characteristics, as well as gene sequence and phylogenetic analysis. Further, the whole genome of isolate was sequenced and predicted to contain one single circular chromosome of 1,776,777 bp with a GC content of 37.
