The activation effect of Klebsiella aerogenes on the immune-related genes of Macrobrachium rosenbergii
During the spring of 2024, an outbreak of mass mortality in Macrobrachium rosenbergii occurred on numerous farms in Gaoyou County, Jiangsu Province. From the naturally infected M. rosenbergii, a dominant strain named MRW3 was isolated and subsequently identified as Klebsiella aerogenes through molecular diagnostics and morphological analysis. In addition, various immune parameters of M. rosenbergii in response to MRW3 infection were monitored at different time points in the gills, hemolymph, hepatopancreas and intestines.The purpose of the present study is to provide a scientific reference for the breeding and disease prevention of M. rosenbergii.
