Secreted peptidases contribute to virulence of fish pathogen Flavobacterium columnare [PDF]
Frontiers in Cellular and Infection Microbiology, 2023 Flavobacterium columnare causes columnaris disease in freshwater fish in both natural and aquaculture settings. This disease is often lethal, especially when fish population density is high, and control options such as vaccines are limited.
