Abstract(s)

Bonamiosis is a disease caused by protozoan parasites of the genus Bonamia (phylum Haplosporidia) that has been responsible for mass mortalities in different oyster species worldwide (for review see Bower 2011; Engelsma et al. 2014). Within the genus Bonamia, there are four known species, namely B. ostreae (Pichot et al. 1980), B. rougheyi (Farley, Wolff & Elston 1988), B. exitiosa (Hine, Cochennec-Laureau & Berthe 2001) and B. perspora (Carnegie et al. 2006). B. exitiosa was originally described in Ostrea chilensis in New Zealand (Hine et al. 2001), and since then, it has been observed in several other countries. In Europe, B. exitiosa was detected for the first time in 2007 in the Atlantic coast of Spain (Abollo et al. 2008).
