Article Synopsis
- There has been significant mass mortality of noble pen shell in various Mediterranean regions over the past seven years linked to a picornavirus that affects immune cells.
- A study analyzed specimens from Spain and Italy using electron microscopy and sequencing to identify the virus and understand its impact on the immune cells.
- Results showed the virus's presence in 100% of the samples, leading to lower total hemocyte counts and indicating severe immune dysfunction and viral replication in affected animals.
Article Synopsis
- From May to October 2019, the Croatian coastline experienced multiple mass mortality events (MMEs) that advanced about 350 km due to surface sea currents moving from southeast to northwest.
- Investigations revealed that 70% of affected animals tested positive for a specific pathogen, with severe lesions occurring when both pathogens were present together in nearly 46% of moribund individuals.
- Areas with lower exposure to major sea currents showed fewer cases of mortality or symptoms, highlighting them as potential sources for healthy individuals that could aid in recovery efforts.
We studied the bioaccumulation of metals and PAHs, the pathological conditions, regressive phenomena and pathogens in wild Mytilus galloprovincialis taken along the North Pier facing the former second Italian largest steelworks of Bagnoli. There was no Cd and Pb bioaccumulation with respect to the EU role 221/2002. Metal shell index decreased as follows: Pb > Ni > Zn > Cu and correlates with the pollution state.

The Unionids freshwater mussels are a group of worldwide distributed bivalves residing small ditches and ponds, lakes, canals and rivers, often used as animal test in eco-toxicological studies. Once one of the most abundant bivalve molluscs in ancient rivers around the world, now many of them are declining in many countries and consequently are nearly extinct in many areas.
