Co-designing and building an expert-elicited non-parametric Bayesian network model: demonstrating a methodology using a Bonamia Ostreae spread risk case study. [PDF]
Risk Anal, 2022 Abstract The development and use of probabilistic models, particularly Bayesian networks (BN), to support risk‐based decision making is well established. Striking an efficient balance between satisfying model complexity and ease of development requires continuous compromise.

Etude de Bonamia Ostreae. Essais d'infestations expérimentales [PDF]
, 1981 L'ostréiculture, depuis une dizaine d'années, subit de graves crises dues à des épizooties successives. La première, causée par Marteilia refringens (1969 à 1975), n'a pas atteint les centres vitaux de l'ostréiculture. La deuxième, due à Bonamia ostreae, mise en évidence en juin 1979 à l'Ile Tudy, touche presque tous les centres ostréicoles bretons ...

Detection of Bonamia ostreae in fixed Ostrea edulis tissues by use of specific PCR assays
, 2007 Infection by the parasite Bonamia ostreae has infected and caused major mortality of the flat oyster, Ostrea edulis, over the last 25 years throughout the coasts of Europe and the United States of America. The conventional techniques for the diagnosis of infection with Bonamia ostreae are typically by histology and cytology. Both have a low sensitivity

Freshwater Haplosporidian Diversity Associated With Invasive Non-Native Bivalves in the River Thames, Including Haplosporidium raabei Infecting Dreissena polymorpha. [PDF]
J Eukaryot MicrobiolABSTRACT Haplosporidians are protistan parasites of aquatic invertebrates. Described here is the first report of the zebra mussel (Dreissena polymorpha) parasite Haplosporidium raabei in the River Thames, London, UK. The prevalence of this protist in the upper tidal Thames, Richmond, was higher than previously reported in other studies from the UK and ...

Detection and characterization of Bonamia ostreae in Ostrea edulis imported to China [PDF]
Diseases of Aquatic Organisms, 2013 The protozoan parasite Bonamia ostreae is a destructive pathogen of flat oysters and has been reported to be widespread in Europe and North America. The biological characteristics of this unicellular parasite are still not fully understood. In this study, 104 Ostrea edulis imported from the USA to the Guangdong province of China for consumption were ...
