Objective: Gilt-head seabream (Sparus
aurata) is an important species for Turkish aquaculture and bacterial diseases
are one of the limiting factors for the production of this species. The aim of
this study is the identification of the bacterial disease agents in cultured
gilt-head seabream in Turkey and the determination of their antibacterial
susceptibilities. 

Materials and Methods: In this study, 27
diseased gilt-head seabream samples between 3-130 g, showing various clinical
symptoms, were examined bacteriologically. Bacterial isolates recovered from
moribund fish samples were identified by using standard bacteriological methods
and API 20E rapid identification strips. Antibiotic susceptibility tests of 10
different substances against these isolates were determined by using
Kirby-Bauer disc diffusion method. 

Results: Vibrio anguillarum, V.
scophthalmi, V. logei, V. harveyi, Pseudomonas anguilliseptica, P. stutzeri,
Staphylococcus sp. and Micrococcus luteus isolates were isolated from diseased
fish samples as pure and mixed infection. It was detected that API 20E may give
erroneous results for fish pathogenic bacteria since they are not included in
the database of the kit. Generally, enrofloxacin, florphenicol and
oxytetracycline were found to be the most effective antibiotics against
bacterial isolates. 

Conclusion: This study is the first report
for V. scophthalmi, V. logei, V. harveyi, P. stutzeri and M. luteus infections
of gilt-head seabream in Turkey.
