Biochemical Differences and Rapid Identification of Yersinia ruckeri and Lactococcus garvieae Isolated from Aquaculture (Akuakültürden İzole Edilen Y. ruckeri ve L. garvieae İzolatlarının Hızlı Teşhisi ve Biyokimyasal Farklılıklarının Belirlenmesi)

Abstract

Aquaculture has growing much more than 100% at the last decade. Especially rainbow trout is the most economically important fish in aquatic species, yet the bacterial infections limit freshwater fish production especially Yersinia ruckeri and Lactococcus garvieae. There are many identification reports on the bacterial agent but each study should be supported with detailed biochemical features. Therefore, we aimed of this study, determination of biochemical differences and identify two bacteria in a short time by using rapid test kits. 30 isolates of each Y. ruckeri and L. garvieae used that are represent of different regions of Turkey were used and biochemical characteristics were determined by basic microbiologic test and API RAPID test kits. Y. ruckeri is the most heterogenetic biochemical structure comparing to L. garvieae. All isolates were successfully identified within 5-7 hours by using rapid test kits while there are some differences between each other. The extensive biochemical differences of Y. ruckeri and L. garvieae were shown in the present study.
