Histological survey of four species of cultivated molluscs in Chile susceptible to OIE notifiable diseases

Shellfish cultured in Chile were analyzed to detect the presence of diseases notifiable to OIE (Office International des Epizooties: the World Organization for Animal Health). Tissue samples of the susceptible species, the abalones Haliotis discus hannai, H. rufescens, and oysters Crassostrea gigas,...
