<i>Vibrio ponticus</i> and <i>Vibrio harveyi</i> infection in snubnose pompano, <i>Trachinotus blochii</i>, from marine aquarium

Vibriosis in a mixed community with Vibrio harveyi and Vibrio ponticus in adult snubnose pompano, Trachinotus blochii , is documented from a marine aquarium. The disease was clinically manifested by reduced feeding activity, lethargy, abnormal swimming behaviour, extensive and focal superficial ulceration in dorsal region, and mild opaque eye with haemorrhage. Histopathological examinations revealed moderate to severe epidermal necrosis and ulceration with scale pocket and dermal oedema. Scales were often displaced, distored or absent in skin sections. Cutaneous lesions were associated with a lymphocytic inflammatory infiltrate noted multifocally throughout the dermal layers. Grossly, the hepatopancreas had an area of pallor; on histological examination, the hepatopancreas displayed hepatocyte vacuolation and congestion.
