Effective control of parasitic sea lice (including Lepeophtheirus salmonis and Caligus elongatus), is a major challenge currently facing sea cage salmon aquaculture. Emamectin benzoate (EMB; SLICE®), a macrocyclic lactone (ML), has been the drug of choice for sea lice treatment over the past decade...

Immune function gene expression in Mya arenaria haemocytes was evaluated following in vivo infection with Vibrio splendidus LGP32-GFP and 7SHRW. Elongation factor 1α (EF-1α) with 2 (EF-2), after challenge with LGP32-GFP, and EF-1α with the ribosomal protein S-18, after challenge with 7SHRW, were ...

Hemocytes Constitute the cellular part of the mollusc immune system and are involved in phagocytosis; the production of toxic oxygen radicals, antimicrobial peptides, opsonizing molecules, and lysozymes; digestion, excretion, and nutrient transport. In this study, we investigated the phenotypic resp...

The aim of this study is to investigate the effects of the pesticides/polycyclic aromatic hydrocarbon mixture on aryl hydrocarbon receptor (AhR), p53 and ubiquitin mRNA level in haemocytes of Mya arenaria exposed to a mixture of chlorothalonil, mancozeb and benzo[a]pyrene (BaP) for 48 and 72 h. AhR,...

Host-pathogen interaction models in aquatic species are useful tools for understanding the pathogenicity of diseases in cultured and wild populations. In this study we report the differential in vivo response of soft-shell clam (Mya arenaria) hemocytes against two strains of Vibrio splendidus. Respo...

Reverse transcriptase (RT) activity has been reported in bivalves affected by haemic neoplasia (HN). Since all retroviruses have RT, detection of RT activity was regarded as evidence for the retroviral etiology of HN. This study investigates the relationship between RT levels and the progress of HN ...

Immune function gene expression in Mya arenaria haemocytes was evaluated following in vivo infection with Vibrio splendidus LGP32-GFP and 7SHRW. Elongation factor 1alpha (EF-1alpha) with 2 (EF-2), after challenge with LGP32-GFP, and EF-1alpha with the ribosomal protein S-18, after challenge with 7SH...

Although the mollusc immune system has been studied at the cellular level, the response to pathogens at gene expression level has not been thoroughly investigated. This study aimed to investigate the early molecular response of hemocytes of soft-shell clams, Mya arenaria, to Vibrio splendidus strain...

Flow-cytometric characterisation of bivalve haemocytes is usually performed by light-scatter profiles based on size and complexity of the cells. Additional means of characterisation such as specific fluorescent dyes are not commonly used to discriminate cell subpopulations in challenged and unchalle...
