Highlights • Previous studies of housekeeping genes selection in mollusc species were reviewed. • Ten candidate housekeeping genes were assessed in ark shell under given conditions. • RL7 and EF-1a were the most stable genes across tissues in ark shells. • RL15 appeared more stable than others under a variety of given conditions. • 18s … Continue reading Validation of housekeeping genes for quantitative mRNA expression analysis in OsHV-1 infected ark clam, Scapharca broughtonii
The aquaculture sector is significantly behind plant and farm animal production in applying selective breeding, in spite of the fact that it has been suggested that the world aquaculture production could be doubled in 13 years if breeding programmes were supplying stocks for the farmed species. It is estimated that as late as in 2010, only … Continue reading Selection response in fish and shellfish: a review
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?
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
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)
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 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
