Popis: | Flavobacteriosis are emerging infectious diseases in marine fish aquaculture, above all in the Mediterranean basin, characterized by cutaneous ulcers and erosions with cachexia and delayed growth, rarely lethal for the affected specimens. Among marine fish species, seabream and seabass are the most sensitive to the infection and recently also common dentex farmed in Sardinia. Authors describe the features characterizing a spontaneous outbreak occurred in a Sicilian off-shore farm of common dentex (Dentex dentex). On February 2003 infected specimens were sampled and microbiological and histopathological assays were performed. Cutaneous changes of diseased specimens were erosions with depigmentation and/or haemorrhages, ulcers deepened beneath the musculature, fin and caudal erosions. By the histological point of view, subcutaneous tissue was characterized by necrosis, parvicellular infiltration and several filamentous bacteria. Extent of focus and severity of symptoms confirmed the dangerous potential of flavobacterial infections for the Mediterranean mariculture and a limiting factor in common dentex farming development. |
