title: Klebsiella aerogenes
design: 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 MRW1 was isolated and subsequently identified as Klebsiella aerogenes through molecular diagnostics and morphological analysis. Furthermore, its complete genome sequence was determined.
