Transcriptomic analysis was performed on the kidney tissue of channel catfish (Ictalurus punctatus) infected with pathogenic and non-pathogenic Aeromonas veronii.

his project employs RNA-Seq technology to conduct a comparative transcriptomic analysis of the head kidney in Channel Catfish (Ictalurus punctatus) challenged with pathogenic and non-pathogenic Aeromonas veronii. The study focuses on identifying differentially expressed genes (DEGs) and enriched signaling pathways within the head kidney tissues in response to varying bacterial virulence. These findings aim to elucidate the molecular basis of the host immune defense and provide a theoretical foundation for understanding A. veronii pathogenesis and developing targeted biocontrol strategies in aquaculture.
