Edwardsiella tarda the world where "E. tarda" is found and they were hoping to discover how similar levels may be in the United States. This could offer scientists a "baseline for the development of more reliable molecular diagnostic tools." The study found that two distinct genotypes do exist within "E. tarda" but does state that it's completely possible that there are more. This study will be used to improve the accuracy of "molecular diagnostics to better understand the role these genetically distinct "E. tarda" groups play in fish health." Abayneh T.
