lesions caused by virulent aeromonas hydrophila in farmed catfish ( ictalurus punctatus and i. punctatus × i. furcatus) in mississippi.in 2009, a virulent strain of aeromonas hydrophila caused severe disease and high mortalities (motile aeromonad septicemia variant [masv]) in farmed channel catfish ( ictalurus punctatus) and hybrid catfish ( i. punctatus × i. furcatus) in eastern mississippi and alabama. as is common in mas, there is severe hemorrhagic dermatitis with ulceration, as well as abdominal hyperemia, petechiation, and mild ascites. additional findings in masv cases include panophthalmitis and orbital cellulitis, lead ...201728482758
rapid quantitative detection of aeromonas hydrophila strains associated with disease outbreaks in catfish aquaculture.a new strain of aeromonas hydrophila has been implicated in significant losses in farm-raised catfish. outbreaks attributable to this new strain began in alabama in the summer of 2009 and have spread to arkansas and mississippi in subsequent years. these outbreaks mostly afflicted market-sized fish and resulted in considerable losses in short periods of time. the present research was designed to develop an expeditious diagnostic procedure to detect the new strains of a. hydrophila due to the rap ...201323847227
an asian origin of virulent aeromonas hydrophila responsible for disease epidemics in united states-farmed catfish.since 2009, catfish farming in the southeastern united states has been severely impacted by a highly virulent and clonal population of aeromonas hydrophila causing motile aeromonas septicemia (mas) in catfish. the possible origin of this newly emerged highly virulent a. hydrophila strain is unknown. in this study, we show using whole-genome sequencing and comparative genomics that a. hydrophila isolates from diseased grass carp in china and catfish in the united states have highly similar genome ...201424895303
