Bullfrog is one of the most important economic aquatic animals in China. It is widely cultured in southern China, and is a key breed recommended as an industry of poverty alleviation in China. During recent years, a fatal bacterial disease has often been found in cultured bullfrogs. The clinical manifestations of the diseased bullfrogs were severe intestinal inflammation and even anal prolapse. A bacterial pathogen was isolated from the diseased bullfrog intestines. The bacterium was identified as Vibrio cholerae using morphological, biochemical and 16S rRNA phylogenetic analysis. In this study, V. cholerae was isolated and identified from diseased bullfrogs for the first time, providing a basis for the diagnosis and control of the disease. At the same time, it was also found that V. cholerae may be transmitted to humans from bullfrogs through bullfrog food and aquaculture water, creating a serious threat for human health. Therefore, society should pay attention to the modes of transmission of Vibrio cholerae from bullfrog and formulate reasonable safety measures to avoid disasters.
