Diagnosis of Vibriosis in Humpback Red Snapper (Lutjanus gibbus Foorsskal, 1775) and Golden Trevally (Gnathanodon speciosus Foorsskal, 1775) in a Marine Aquarium, Turkey
Abstract
This study was carried out to determine the reason of mortalities in
humpback red snapper (Lutjanus gibbus) and golden trevally (Gnathanodon speciosus) kept
in a marine aquarium in Turkey. Moribund fish showed diffuse
haemorrhages on upper and lower jaws, superficial
and ulcerative skin lesions, tail rot and pale gills. Internally, clear fluid
in peritoneal cavity and pale liver were observed. The
isolated bacteria were identified as Vibrio
harveyi according to their morphological, physiological, biochemical
characteristics and API 20E results. These bacterial identifications were also
confirmed with 16S rRNA gene sequence analysis. The isolates were determined to
be sensitive to sulphamethoxazole/ trimethoprim, florphenicol
and flumequine and were resistant to erythromycin, kanamycin and
ampicillin. Vibrio
harveyi infected fish generally showed epithelial hyperplasia in the
gill filaments, ulcerative skin lesions, degeneration or
necrosis of the hepatic cells, kidney tubules and parenchyma cells of the
spleen, multifocal melanomacrophage centres in the kidney and reduced
hemopoietic tissue in the spleen.
