A potential microRNA regulation of immune-related genes in invertebrate haemocytes

Bivalve mollusks have been employed as sentinel organisms in environmental health programs due to their sedentary lifestyle, filter-feeding behavior and their ability to accumulate pathogens or toxin molecules inside tissues. Endocrine disrupting chemicals (EDCs) can be up taken and bioaccumulated, and due to sensibility of mollusks to these EDCs, being able to cause immune alterations. … Continue reading A potential microRNA regulation of immune-related genes in invertebrate haemocytes

LRFN (leucine-rich repeat and fibronectin type-III domain-containing protein) recognizes bacteria and promotes hemocytic phagocytosis in the Pacific oyster Crassostrea gigas

In bivalve mollusks, circulating hemocyte mediated phagocytosis is one of the primary ways to eliminate invading microbes. Here, we have identified one CgLRFN (leucine-rich repeat and fibronectin type-III domain-containing protein) in the Crassostrea gigas as a novel transmembrane LRR (Leucine-rich repeat) domain containing protein in C. gigas, homologous to the jawless fish VLR protein, that … Continue reading LRFN (leucine-rich repeat and fibronectin type-III domain-containing protein) recognizes bacteria and promotes hemocytic phagocytosis in the Pacific oyster Crassostrea gigas

Tumor necrosis factor receptor-associated factor 3 from Anodonta woodiana is an important factor in bivalve immune response to pathogen infection

Tumor necrosis factor receptor-associated factor 3 (TRAF3) is a multifunctional adaptor protein in innate and acquired immune system that plays a key role in the regulation of the RIG-I-like receptor (RLR) and Toll-like receptor (TLR) signaling pathway in mammals. However, the immune function of TRAF3 homologs in freshwater mollusks is not well understood. In this … Continue reading Tumor necrosis factor receptor-associated factor 3 from Anodonta woodiana is an important factor in bivalve immune response to pathogen infection

Laboratory simulation reveals significant impacts of ocean acidification on microbial community composition and host-pathogen interactions between the blood clam and Vibrio harveyi

It has been suggested that climate change may promote the outbreaks of diseases in the sea through altering the host susceptibility, the pathogen virulence, and the host-pathogen interaction. However, the impacts of ocean acidification (OA) on the pathogen components of bacterial community and the host-pathogen interaction of marine bivalves are still poorly understood. Therefore, 16S … Continue reading Laboratory simulation reveals significant impacts of ocean acidification on microbial community composition and host-pathogen interactions between the blood clam and Vibrio harveyi

Preventive effect of three kinds of bacteriophages to control Vibrio coralliilyticus infection in oyster larvae

Vibrio corallilyticus is a well-known pathogen of coral. It is also infectious to a variety of shellfish species, including Pacific oyster (Crassostrea gigas) larvae. V. corallilyticus is remained to be a major constraint in marine bivalve aquaculture practice, especially in artificial seed production facility. Owing to the high mortality and contagious nature of the pathogen, … Continue reading Preventive effect of three kinds of bacteriophages to control Vibrio coralliilyticus infection in oyster larvae

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

S.O.S. Pinna nobilis: a mass mortality event in western Mediterranean sea

A mass mortality event (MME) impacting the bivalve Pinna nobilis was detected across a wide geographical area of the Spanish Mediterranean Sea (Western Mediterranean Sea) in early autumn 2016. Underwater visual censuses were conducted across several localities separated by hundreds of kilometers along the Spanish Mediterranean coasts and revealed worrying high mortality rates reaching up … Continue reading S.O.S.
