Fatty Liver Disease and Bacterial Co-Infection in Cultured Marine Fish

In the present study, we sampled sea bream and bass, weighing 400-450g, for routine microbiological, hematological, macroscopical histopathological examinations. Samples were taken from seemingly healthy fish, which displayed increased feed conversion rates, signs of cold shock slow movement. Routine bacteriological analyses included basic microbiological oxidase catalase activity, Gram staining O/F fermentation using API test kits. Furthermore, 16S rRNA gene sequencing was performed identification. Serum biochemical hematological values determined a Vetscan®VS2 analyzer blood smears. Internal organs examined by techniques. Hepatic fat accumulation necrosis noted, liver damage observed to be associated with significant alterations in enzymes. Due multi-organ dysfunction serious disorders, primarily Vibrio alginolyticus also Alteromonas Pseudoalteromonas species isolated affected fish co-infections detected.
