Abstract

Abstract: To explore the causes of outbreaks disease of yellow catfish in some areas of Hubei province, we investigated the production situation in field. Aeromonas veronii and Plesiomonas shigelloides were isolated and identified from disease fish. The results of antimicrobial susceptibility test indicated that the Aeromonas veronii was susceptible to neomycin sulfate and flumequine, resistant to thiamphenicol, florfenicol and sulfamonomethoxine sodium. Plesiomonas shigelloides was only sensitive to flumequine, resistant to other seven kind drugs. Comprehensive factors such as temperature, water quality, and feeding conditions have analyzed the causes of outbreaks of yellow catfish. It was believed that this outbreak was mainly caused by bacterial infection and was closely related to factors such as severe temperature fluctuations, overfeeding, and deterioration of water quality. The drug susceptibility test has determined the types of available drugs and provided countermeasures for the prevention and control of this type of yellow catfish disease.

Key words: Pelteobagrus fulvidraco, Aeromonas veronii, Plesiomonas shigelloides, antimicrobial susceptibility test
