Abstract

The study was carried out to investigate the histopathological changes in the shellfish samples associated with the Vibrio species which are collected from the Kali Estuary and also collected from the Fish market of Karwar. The collected samples were soon processed in lab to avoid the contamination. The Vibrio species were isolated and identified from the Meretrix meretrix samples using standard microbiological and molecular protocol. The maximum of Vibrio parahaemolyticus and Vibrio alginolyticus species were isolated and identified in the samples collected from market when compared to wild from the Estuary. The histopathological changes were observed in the gills, mantel and the digestive tissues. Observed alterations included haemocyte infiltration, inflammation, and necrosis within gill lamellae and mantle tissues. This is due to the pathogenic Vibrio species. Keywords: Meretrix meretrix, Histopathological changes, Vibrio parahaemolyticus and Vibrio alginolyticus.
