  Bacterial pathogens such as vibrio species cause a significantly high economical loss in the aquaculture sector. Thus, the main objective of this study was to isolate and identify Vibrio species and evaluated the hematological, biochemical, and histopathological changes in experimentally infected Nile tilapia with 0.1 ml of 1×106 colonyforming units (CFU)/ml of Vibrio species isolates. The clinical examination of the infected Nile tilapia revealed all fish became less active and the feeding rate decreased, the dorsal portion of the body became darkened. Fin rot appeared especially at the tips of the caudal fin and showed extensive hemorrhages at the ventral body part. The results also showed reduction in hemoglobin, hematocrit, protein, albumin, glucose, globulin, and triglyceride contents in the infected fish tha.. View more»
