Alteration of host-pathogen interactions in the wake of climate change – Increasing risk for shellfish associated infections?

The potential for climate-related spread of infectious diseases through marine systems has been highlighted in several reports. With this review we want to draw attention to less recognized mechanisms behind vector-borne transmission pathways to humans. We have focused on how the immune systems of edible marine shellfish, the blue mussels and Norway lobsters, are affected … Continue reading Alteration of host-pathogen interactions in the wake of climate change – Increasing risk for shellfish associated infections?

Ultrastructural analysis of Apicomplexa-Like parasites in two conch species Laevistrombus canarium and canarium urceus from Johor Straits, Malaysia

The tropical conch, Laevistrombus canarium (Linnaeus, 1758) and Canarium urceus (Linneaus, 1758) are ecologically and economically important shellfish species in Malaysia and neighboring region. Their populations, however are currently declining and this histopathological study investigates the aspect of parasitism and diseases that may affect their well-being. Conch samples were randomly collected from their natural habitat … Continue reading Ultrastructural analysis of Apicomplexa-Like parasites in two conch species Laevistrombus canarium and canarium urceus from Johor Straits, Malaysia

Molecular identification and functional analysis of two variants of myeloid differentiation factor 88 (MyD88) from disk abalone (Haliotis discus discus)

Myeloid differentiation factor 88 (MyD88) is a crucial adaptor protein of the Toll-like receptor (TLR)- and interleukin 1 receptor-mediated signaling pathways and is involved in a diverse array of inflammatory responses via NF-κB activation. In the present study, two MyD88 variants were identified from disk abalone (Haliotis discus discus) and designated AbMyD88-2 and AbMyD88-X. The … Continue reading Molecular identification and functional analysis of two variants of myeloid differentiation factor 88 (MyD88) from disk abalone (Haliotis discus discus)

Prevalence of Marteilia spp. in thirteen shellfish species collected from China coast

Marteilia spp. is listed as a notifiable parasite by the Office International des Epizooties (OIE), and cause physiological disorders and eventually death of the shellfish. Little is known about the prevalence of Marteilia spp. in shellfish of China. Therefore we investigated the prevalence of Marteilia spp. in 13 species of shellfish collected in the coastal … Continue reading Prevalence of Marteilia spp. in thirteen shellfish species collected from China coast

The immune response of Mytilus edulis hemocytes exposed to Vibrio splendidus LGP32 strain: A transcriptomic attempt at identifying molecular actors

The marine mussel Mytilus edulis, tolerant to a wide range of environmental changes, combines a key role as a sentinel species for environmental monitoring programs and a significant economic importance. Mortality events caused by infective agents and parasites have not been described in mussels, which suggests an efficient immune system. This study aims at identifying … Continue reading The immune response of Mytilus edulis hemocytes exposed to Vibrio splendidus LGP32 strain: A transcriptomic attempt at identifying molecular actors

VIVALDI, Preventing and mitigating farmed bivalve diseases, HORIZON2020

The overarching goal of VIVALDI is to increase the sustainability and competitiveness of the European shellfish industry by improving the understanding of bivalve diseases and by developing innovative solutions and tools for the prevention, control and mitigation of the major pathogens affecting the main European farmed shellfish species: Pacific oyster (Crassostrea gigas), mussels (Mytilus edulis … Continue reading VIVALDI, Preventing and mitigating farmed bivalve diseases, HORIZON2020

Review of parasites and pathologies of the main bivalve species of commercial interest of Argentina and Uruguay, southwestern Atlantic coast

A systematic review of the parasites and pathologies of the main important commercially bivalve species from Argentina and Uruguay has been done. Bacteria, algae, Perkinsozoa, Haplosporidia, Ciliophora, Apicomplexa, Turbellaria, Trematoda, Cestoda and Nemertea have been found infecting natural populations of bivalve species. Disseminated neoplasia has been recorded in mussels from culture causing gonadal castration and … Continue reading Review of parasites and pathologies of the main bivalve species of commercial interest of Argentina and Uruguay, southwestern Atlantic coast
