Dual transcriptional analysis provides insights into the replicative niche of <i>P. salmonis</i> and the host response during infection

replication and provide a framework for understanding host-pathogen interactions during infection. IMPORTANCE: proliferates and situating these features within the broader landscape of intracellular bacterial strategies, this work advances understanding of host-pathogen interactions in non-mammalian systems and provides a foundation for future functional studies relevant to aquaculture and intracellular microbiology.
