Hice la tesis trabajando con un bicho que se llama Bonamia en honor a un francés apellidado Bonami (como buen palabro francés, agudo). Pues no había forma de que los anglos dijeran Bo-na-mi-a. Había que dicer Boneimia para que no se escojonaran. Lo de chilensis mejor lo dejo para otra...

A non-invasive test for the deadly oyster parasite Bonamia ostreae is at least as good as traditional tissue sampling, and often more effective than water-based environmental DNA techniques.

Speaking of oysters, my first publication on #Bonamia with @mrhenryslane.bsky.social is now out in #Parasitology! We used #ddPCR to compare the infection intensity of two closely related oyster #parasites found in New Zealand flat oysters. doi.org/10.1017/S003...

This trip was for the Bonamia ostreae surveillance, and so I can't comment on oyster numbers from this sampling. The overall oyster quality seemed up, even if the beds across Foveaux remain quite varied.

🌐🧪🦪 Parasites such as #Bonamia_exitiosa are capable of devastating #Oyster populations and identifying #Carriers can help minimize the spread of #Disease. Could the widely distributed #PacificOyster have aided in the #Dispersal of Bonamia? bit.ly/dao_161_39

Kallen Sullivan, a PhD student from the Bean's lab at Roslin presented her awesome work on developing cell culture in oysters 🦪🧫🔬 to study oyster immune response to bonamia infection. I'm always amazed by the different organs you can find in a rock, an oyster sorry 😅

We used gene copy numbers for species-specific digital droplet PCR (ddPCR) assays to compare infection intensity between two parasite species. Bonamia exitiosa has been detected in New Zealand since the 80s, whereas B. ostreae is an introduced species first detected in 2015.

Right? Don’t worry, “The USFWS issued a Biological Opinion dated 10 November 2020, and determined that the Proposed Action is not likely to jeopardize the continued existence of [sensitive and protected species]”

@altfws.altgov.info remind me who was president November 10, 2020 🤔
Several sensitive and protected species may occur within the proposed project areas. A Biological Assessment was prepared and submitted to the U.S. Fish and Wildlife Service (USFWS) consistent with the Endangered Species Act Section 7 Consultation on 16 April 2020. The Navy determined that the Proposed Action may affect, and is likely to adversely affect, Florida bonamia, Lewton's polygala, scrub buckwheat, Florida scrub-jay, eastern indigo snake, gopher tortoise, and sand skink due to the potential for fire caused by high-explosive munitions; mortality from explosions and vehicle traffic on the range; and/or increased exposure to aircraft overflights. It is expected that a relatively low but unquantifiable number of these species may be affected by the Proposed Action, representing a small fraction of the population. The potential for direct harm to individuals within the proposed project areas is unlikely. The USFWS issued a Biological Opinion dated 10 November 2020, and determined that the Proposed Action is not likely to jeopardize the continued existence of these species.

A very popular seafood in New Zealand, most of the catch caught in the vicinity of Bluff (hence the common name). However, the population has been severely affected by the haplosporidian parasites, Bonamia exitiosa and the introduced B. ostreae.

Ocean currents drive disease spread between oyster reefs: Research identifies restoration sites at risk

Our results indicate that 1) infections of introduced Bonamia ostreae are more intense than B. exitiosa, and 2) concurrent infections of both Bonamia parasites have similar intensities to single-species infections, with no detectable interactive effects.
A figure showing the infection intensity of infection groups, using ddPCR gene copy number. There's a statistically significant difference between B. exitiosa and B. ostreae groups. A similar diagram, with singles-species infection and coinfection groups per species. Again, there's a statistically significant difference between the two parasites.

"by the 1960s, the oyster population was crippled by overfishing, the few remaining reefs were then wrecked by the Bonamia ostreae disease. This led to the introduction of the Pacific rock oyster to boost stocks – [...] the abundant Pacific is fuelling the current boom."
