Confirmation of Neoparamoeba perurans on the gills of Atlantic salmon during the earliest outbreaks of amoebic gill disease in Ireland

Molecular diagnostics have made it possible to identify Neoparamoeba perurans as the causative agent involved in the earliest AGD outbreaks in Ireland. A range of other putative pathogens, associated with gill disease were also detected indicating that they have been present in Irish aquaculture for over 20 years.
