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,...

description 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, and Ostrea chilensis cultured in Chile were collected in winter and summer. Histological sections were performed of all species; furthermore, tissue from the Chilean oyster (O. chilensis) was processed for transmission electron microscopy (TEM) to describe the Bonamia-like protozoan detected in the haemocytes of some oysters. The only pathogen from the list of notifiable diseases of the OIE was Xenohaliotis californiensis in H. rufescens. This bacterium formed intracellular inclusions in digestive epithelia, mainly in the post-esophagus and digestive gland. The ultrastructural description of the Bonamia -like protozoan shows it is similar in some features and different in others from the species B. ostreae. and B. exitiosa included in the list of notifiable diseases of the OIE. Se examinaron moluscos cultivados en Chile para detectar la presencia de enfermedades de declaración obligada a la OIE (Office International des Epizooties: Organización Mundial de Sanidad Animal). Se tomaron muestras de tejidos, en invierno y en verano, de las especies susceptibles que se cultivan en el país, los abalones Haliotis discus hannai y H. rufescens, y las ostras Crassostrea gigas y Ostrea chilensis. Se realizaron cortes histológicos de todos los moluscos obtenidos y para el caso de ostra chilena, se procesó además tejido para observación en microscopio electrónico de transmisión (MET) para describir al protozoo tipo Bonamia presente en los hemocitos de algunas ostras. El único patógeno de declaración obligada a la OIE que se encontró fue Xenohaliotis californiensis en H. rufescens, bacteria que se encontró formando inclusiones intracelulares en epitelios digestivos, principalmente post-esófago y glándula digestiva.
