Reported outbreaks of Edwardsiella piscicida, a bacterial pathogen among cultured and wild fish, have been steadily increasing over the past decade in tandem with climate change–mediated increases in water temperatures. The capacity for this increasingly prevalent fish pathogen to infect and cause disease in mammals is important to understand. Researchers examined the role of temperature on the virulence of E. piscicida to understand its pathogenesis in the context of climate warming trends and better understand its zoonotic potential. Findings revealed downregulation of virulence-related proteins, such as flagellar and Type VI secretion system proteins, at colder temperatures. These findings highlight the potential environmental factors influencing the pathogen’s threat to aquaculture and public health. Supported by ORIP (S10OD026918, T32OD011147).
