Bonamia disease was first detected in Ireland in 1987 in Cork Harbour where heavy mortalities occurred. Subsequently the disease was diagnosed in 2 other locations in the West of Ireland. In one case there were serious mortalities whereas in the other no abnormalities were observed. The paper describes the investigations carried out on the disease in Ireland and discussed their significance.
