Infection in Wild Trahira () and Farmed Arapaima () in Brazil: An Interspecies Transmission in Aquatic Environments Shared with Nile Tilapia ().

is an important pathogen responsible for cases of high mortality in farmed and wild fish worldwide. In Brazil, this bacterium has been commonly associated with outbreaks in Nile tilapia farms, but other native fish species are also susceptible. Since floating cages are one of the most common culture systems used in the country, the close contact between farmed tilapia and native fish species presents a risk concerning the transmission of this pathogen.
