Competitive Bacteria Inhibiting Yersinia ruckeri

Abstract

Pacific freshwater fish are less likely than Atlantic freshwater fish to exhibit Enteric Redmouth Disease (ERM), or Yersiniosis as caused by Yersinia ruckeri. Based on the hypothesis that these fish may harbor commensal bacteria that inhibit Y. ruckeri growth, we isolated many kinds of commensal bacteria from fish intestines that we have collected from Alaska and local streams. Using co-culture experiments, we have conducted competitive assays to determine if the bacteria found in the gut biomes of these fish inhibit the growth of Y. ruckeri. These may be potential probiotic organisms that could provide resistance to ERM disease.
