Bilateral Exophthalmos: The Most Important Sign of Lactococcosis in Rainbow Trout (Oncorhynchus mykiss)
Abstract
In this study, we aimed to investigate
rapidly isolation and identification of Lactococcus
garvieae from rainbow trout (Oncorhynchus mykiss), reared Black Sea
Region, Turkey. The fish with bilateral exophthalmos were
collected from a commercial trout farm. The bacteria were identified as L. garvieae based on some biochemical
tests and Polymerase Chain Reaction (PCR)
assay. Following identification, the
antibacterial susceptibility of bacteria was also determined for five different
antibiotics by the disk diffusion method. All isolates were sensitive to
florfenicol and amoxicillin-clavulanate and resistant to trimethoprim+sulfamethoxazole
and enrofloxacin. Overall this study revealed that the bilateral
exophthalmos may be considered as a pathognomonic symptom for lactococcosis in rainbow trout.
