Bonamia exitiosa Hine et al., 2001 is proposed instead of B. exitiosus as the valid name of Bonamia sp infecting flat oysters Ostrea chilensis in New Zealand ArchiMer
Berthe, Franck; Hine, Mike.
A parasite of the dredge oyster Ostrea chilensis Philippi, previously known as Bonamia sp., was recently described and named Bonamia exitiosus, based on ultrastructural and molecular evidence. The rules governing the names of organisms require correspondence of gender, and the name must be changed from B. exitiosus to B. exitiosa.

Bonamia parasites: a rapidly changing perspective on a genus of important mollusc pathogens ArchiMer
Engelsma, Marc; Culloty, Sarah C.; Lynch, Sharon A.; Arzul, Isabelle; Carnegie, Ryan B..
Organisms of the genus Bonamia are intracellular protistan parasites of oysters. To date, 4 species have been described (B. ostreae, B. exitiosa, B. perspora and B. roughleyi), al though the status of B. roughleyi is controversial. Introduction especially of B. ostreae and B. exitiosa to naïve host populations has been shown to cause mass mortalities in the past and has had a dramatic impact on oyster production. Both B. ostreae and B. exitiosa are pathogens notifiable to the World Organisation for Animal Health (OIE) and the European Union. Effective management of the disease caused by these pathogens is complicated by the extensive nature of the oyster production process and limited options for disease control of the cultured stocks in open water. This...

Whole-genome amplification: a useful approach to characterize new genes in unculturable protozoan parasites such as Bonamia exitiosa ArchiMer
Prado-alvarez, Maria; Couraleau, Yann; Chollet, Bruno; Tourbiez, Delphine; Arzul, Isabelle.
Bonamia exitiosa is an intracellular parasite (Haplosporidia) that has been associated with mass mortalities in oyster populations in the Southern hemisphere. This parasite was recently detected in the Northern hemisphere including Europe. Some representatives of the Bonamia genus have not been well categorized yet due to the lack of genomic information. In the present work, we have applied Whole-Genome Amplification (WGA) technique in order to characterize the actin gene in the unculturable protozoan B. exitiosa. This is the first protein coding gene described in this species. Molecular analysis revealed that B. exitiosa actin is more similar to Bonamia ostreae actin gene-1. Actin phylogeny placed the Bonamia sp. infected oysters in the same clade where...
