Project description:Bacterial strains within a species can differ in traits that shape host–microbe interactions. Using the squid–vibrio symbiosis, we examined how strain-level variation influences host responses. Strains from squid and fish light organs were compared for their effects on Euprymna scolopes gene expression and development. Non-native strains showed reduced colonization success and delayed host phenotypes. Transcriptomic responses were most similar with native isolates and most divergent with a fish-derived strain. These findings demonstrate that fine-scale strain differences shape host compatibility and underscore the importance of strain-level diversity in the establishment of beneficial symbioses.
