In this study, Lactococcus garvieae strains were isolated and identified from sick young fish from some rainbow trout (Oncorhynchus mykiss) farms in Fethiye region. Lethargy, anorexia, exophthalmi with hemorrhage and abdominal dropsy in the sick fish were observed. Hemorrhage in the liver, enlargement of the spleen (splenomegaly) and ascites as internal signs were determined. The strains showed sensitivity to ampicillin, erythromycine, chloramphenicol, sulfamethoxazole, oxytetracycline, tetracycline and trimethoprim and resistant to basitrasin, flumequine, furazolidone, kanamycin, nalidixic acid, oxalinic acid and streptomycine. It was found that the strains harboured plasmids with different sizes according to the results of plasmid analysis results.
