Most of the information contained in these pages was prepared by the EURL for the European project PANDA (Permanent Advisory Network for Diseases in Aquaculture).
Notifiable diseases to the OIE and/or to the European Commission (EC)
- Bonamia ostreae (OIE / EC - endemic)
- Bonamia exitiosa (OIE / EC - endemic*)
- Marteilia refringens (OIE / EC - endemic)
- Perkinsus marinus (OIE / EC - exotic)
- Perkinsus olseni (OIE - endemic)
- Xenohaliotis californiensis (OIE - endemic)
- Mikrocytos mackini ( EC - exotic)
- Abalone herpes-like virus AbHV (OIE - exotic)
(*) Bonamia exitiosa is classified as exotic in EU directive 2006/88, however, the parasite has been discovered in 2007 for the first time in Europe in flat oysters (Ostrea edulis) from Galicia (Spain). Since then, B. exitiosa has also been observed in several other European countries.
