Biotyping of lactococcus garvieae isolated from Turkey

Alabalıklardan izole edilen 20 Lactococcus garvieae suşu fenotipik özellikleri, serolojik özellikleri ve kapsül oluşumu yönünden incelendi. İzolatlar API 20 Strep API 50 CH ve klasik bakteriyolojik yöntemlerle identifiye edildi. Suşların tamamının kapsullü olduğu, kapsullü İspanya suşuna karşı hazırlanmış antiserum ile aglutine olduğu görüldü. Sonuçlar Türkiyeden yapılan izolatların homojen ve biyotip 3 olduğunu, ve İspanyadan yapılan izolatlatlarla biribirine yüksek oranda benzediğini ortaya koydu. Klasik bakteriyolojik incelemede izolatların %40’ının laktozdan asit oluşturabildiği belirlendi.

Türkiye' den izole edilen lactococcus garvieae' ların biyotiplendirilmesi

Twenty Lactococcus garvieae strains isolated from rainbow trout were investigated in phenotypic, serologic and capsule formation. Isolates were identified with API 20 Strep, API 50CH and conventional bacteriologic techniques. All strains were capsulated and agglutinated with antiserum, which raised against capsulated Spanish strain. The results were indicated that high level of homogeneity in Turkish isolates, all were biotype 3 and high similarity between Spanish and Turkey isolates. 40% of the isolates were able to produce acid from lactose in conventional techniques
