AbstractPurposePinna nobilis(fan mussel) is one of the most important endemic bivalve molluscs in the Mediterranean and mass mortality events were observed in these mussels in recent years. In this study, we report mass mortalities caused by Haplosporidium pinnae, which has been spreading in the Mediterranean for 3 years, and reached the Çanakkale Strait, which is the entrance of the Marmara and the Black Sea.Material and methodsField observations during sampling and subsequent histopathological, biochemical, genetic, and microbiological analyses were carried out.ResultsThese analyses showed that H. pinnaeinfection spread among the natural beds of P. nobilis, causing severe tissue damage and oxidative stress. Our phylogenetic analyses suggested that the parasite spread through the Mediterranean much faster than thought. The results showed that vibriosis originating from Vibrio coralliilyticus, Vibrio tubiashii, Vibrio mediterranei, and Vibrio hispanicus, acted together with H. pinnaein infected individuals and caused death.ConclusionIt is highly probable that the spread of H. pinnaeto the Sea of Marmara and the Black Sea may occur earlier than expected, and it was concluded that mass deaths were caused by co-infection with H. pinnaeand a geographically specific marine pathogen that can infect P. nobilispopulations. |
