Fatty Acid Composition in Yersinia ruckeri Strains Isolated from Rainbow Trout Farms

In this study, a total of 33 Yersinia ruckeri isolates were obtained from rainbow trout farms in the five different region of Turkey. We were determined to changes in fatty acids group of the strains. All the isolates were identified as Y. ruckeri based on colonical, cellular morphology and biochemical characters. All Y. ruckeri 11 major fatty acids, including 12:0 (Laurik acid), 14:0 (Miristik acid), 16:0 (Palmitik acid), 16:1n-7 (Palmitoleik acid), 17:1 (Heptadekanoik acid), 18:1n-9c (Oleik acid), 18:2n-6c (Linoleik acid), 18:3n-3c (Alfa-linoleik acid), 22:0 (Behenik acid), 22:1 (Dokosenoik acid) and 24:1 (Tetrakosenoik acid). Compared to isolates biochemical property. There was no different between fatty acids and biochemical characteristics. The results of this study show that the fatty acids composition of Y. ruckeri isolated strains from rainbow trout farms in Turkey is on a large scale homogenous.
