The paper identifies a novel ranavirus causing high mortality in captive wrasses from the Great Barrier Reef and links it to wild hosts.

Reducing the impact of HaHV-1 in Australian abalone: the role of age and immune priming

This study examines how age and immune priming affect susceptibility to HaHV-1 in Australian abalone, finding younger abalone are less susceptible and immune priming with poly(I:C) provides protection.

Multi-Omics Reprogramming Drives a Counterintuitive Reversal of Disease Susceptibility During Ageing

The paper identifies age-related epigenetic, transcriptional, and metabolic reprogramming in oysters that increases tolerance to a viral disease, revealing an evolutionary trade-off between growth and antiviral defense.

Eastern oyster larvae assemble a core bacterial microbiome distinct from hatchery water treatment systems

This study identifies a core bacterial microbiome in eastern oyster larvae that is distinct from hatchery water sources, indicating host-mediated selection rather than passive environmental acquisition.

Roseobacter enrichment early in life facilitates future colonization of Roseobacter bacteria and improves long-term survival against Vibrio aestuarianus in the Pacific oyster

The paper tests if early exposure to Roseobacter bacteria improves Pacific oyster survival against Vibrio aestuarianus at high temperatures, finding a 28-30% survival benefit.
