Özet
Purpose: Pinna 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 C¸anakkale Strait, which is the entrance of the Marmara
and the Black Sea.
Material and methods: Field observations during sampling and subsequent histopathological, biochemical, genetic, and microbiological analyses were carried out.
Results: These analyses showed that H. pinnae infection 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. pinnae in infected individuals and caused death.
Conclusion: It is highly probable that the spread of H. pinnae to 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. pinnae and a geographically specific marine pathogen that can infect P. nobilis
populations.
