Summary
A research team has found that increased expression of the lipa gene in Plesiomonas shigelloides is associated with stronger bacterial attachment, greater biofilm formation, and more severe disease symptoms in southern catfish (Silurus meridionalis). The altered bacteria also triggered substantial changes in the fish's immune response, linking a bacterial metabolic gene to both infection characteristics and host defenses. The findings identify lipoyl synthase, the enzyme associated with lipa, as a potential target for future research into controlling bacterial infections and improving fish health in aquaculture.
