Identification and characterization of TEP family genes in Yesso scallop (Patinopecten yessoensis) and their diverse expression patterns in response to bacterial infection

Thioester-containing protein (TEP) family members are characterized by their unique intrachain β-cysteinyl-γ-glutamyl thioesters, and they play important roles in innate immune responses. Although significant effects of TEP members on immunity have been reported in most vertebrates, as well as certain invertebrates, the complete TEP family has not been systematically characterized in scallops. In this study, … Continue reading Identification and characterization of TEP family genes in Yesso scallop (Patinopecten yessoensis) and their diverse expression patterns in response to bacterial infection

Molecular Characterization of an Endozoicomonas-Like Organism Causing Infection in the King Scallop (Pecten maximus L.)

One of the fastest growing fisheries in the UK is the king scallop (Pecten maximus L.), also currently rated as the second most valuable fishery. Mass mortality events in scallops have been reported worldwide, often with the causative agent(s) remaining uncharacterized. In May 2013 and 2014, two mass mortality events affecting king scallops were recorded … Continue reading Molecular Characterization of an Endozoicomonas-Like Organism Causing Infection in the King Scallop (Pecten maximus L.)

Disease and mortality among Yesso scallops Patinopecten yessoensis putatively caused by infection with Francisella halioticida

During the fall of 2015, up to 40% mortality occurred in juvenile Yesso scallops Patinopecten yessoensis at an aquaculture site in Baynes Sound, British Columbia, Canada. Macroscopic lesions were present in 11% of the scallops, and histopathology consisting of multifocal and diffuse haemocyte infiltration was observed in 44% of the specimens examined. Histologically, small Gram-negative … Continue reading Disease and mortality among Yesso scallops Patinopecten yessoensis putatively caused by infection with Francisella halioticida
