Perkinsus chesapeaki observed in a new host, the European common edible cockle Cerastoderma edule, in the Spanish Mediterranean coast.
Journal of invertebrate pathology(2014)
摘要
Histological observations showed the presence of a Perkinsus sp. parasite in Cerastoderma edule tissues for the first time in the Spanish Mediterranean coast. ITS molecular characterization by PCR-RFLP, in situ hybridization and sequencing, identified the parasite as Perkinsus chesapeaki, with a maximum identity of 99-100% with GenBank P. chesapeaki sequences from France and 97% with P. chesapeaki sequences of North American origin when BLAST analysis was carried out. Furthermore, phylogenetic studies placed the European cockle parasite in a well defined cluster together with the other European isolates. This is the first report of P. chesapeaki in the cockle C. edule.
