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, I isolated many kinds of commensal bacteria from fish intestines collected from Alaska and local streams. In previous studies, I have isolated novel bacteria capable of expressing inhibitory activity against Y. ruckeri via co-culture experiments. One of these bacteria is a strain of Pseudomonas fjordensis. Through genome-wide mutagenesis techniques, a possible gene has been unveiled that may be contributing to this inhibitory activity.
