Article Synopsis
- Edwardsiella piscicida is a fish pathogen affecting multiple species, with unclear reasons for its genetic diversity; this study analyzed 37 isolates from 10 different fish species in North America.
- Using multilocus sequence analysis (MLSA), researchers grouped these isolates into six clades, assessing their virulence in Chinook salmon after introducing the bacteria.
- Results showed high mortality rates (≥83.3%) in salmon infected with certain clades, indicating a genetic basis for the virulence of different strains, highlighting the need for further research on various fish models.*
