Investigation into Cryptosporidium and Giardia in bivalve mollusks farmed in Sardinia region and destined for human consumption

open access: yesItalian Journal of Food Safety, 2013
Cryptosporidium and Giardia are protozoan parasites transmitted by fecal-oral ingestion of (oo)cysts, and are responsible for enteritis in several animal species and humans worldwide.

Mapping molluscan endocrinology: a systematic and critical appraisal

open access: yesBiological Reviews, Volume 101, Issue 2, Page 970-1002, April 2026.
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

Metamorphosis and lncRNAs: A Close Relationship

open access: yesgenesis, Volume 64, Issue 2, April 2026.
ABSTRACT The classical definition of metamorphosis is a post‐embryonic transformation, such as from a tadpole to a froglet. However, recent studies suggest this process occurs to some degree in all vertebrates, as the underlying endocrine and molecular pathways are highly conserved. With the advent of high‐throughput sequencing, transcriptomic data for

Comparative transcriptomic analysis reveals a differential acid response mechanism between estuarine oyster (Crassostrea ariakensis) and Pacific oyster (Crassostrea gigas)

open access: yesEcotoxicology and Environmental Safety
Ocean and coastal acidification (OCA) poses a significant and rapidly emerging threat to mollusks. The physiological resilience of mollusks to OCA varies considerably; however, the underlying molecular mechanisms remain poorly understood.

Evaluation of the Population Genetic Structure of Anadara tuberculosa (Mollusca, Bivalvia) in the Panamanian Pacific

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Our study analyzed the population genetics of Anadara tuberculosa (concha negra) in five Panamanian Pacific mangrove areas using the mitochondrial COI gene. We found high haplotypic diversity and low nucleotide diversity, a pattern that suggests a recent demographic expansion, which was supported by our neutrality tests and a star‐shaped haplotype ...

Cryopreservation of Pacific Oyster, Crassostrea gigas Sperm

open access: yesThe Korean Journal of Malacology, 2013
This study aims to find out a suitable cryoprotective agent (CPA) for cryopreservation and its optimum concentration in order to conduct planned artificial seed production of Pacific oyster, Crassostrea gigas and to preserve superior sperm. For this, we tried to understand toxicity and the effect of cryopreservation by CPA type and concentrations first

Analysis of the Structure and Functioning of the Chudao Oyster Reef Ecosystem in Sanggou Bay, China

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
The study focuses on the Chudao oyster reef ecosystem in Sanggou Bay, China. By investigating the biodiversity, food web structure, and energy flow, the study aims to provide a basis for further exploring the role of oyster reef in maintaining marine ecological environment. ABSTRACT The Chudao oyster reef in Sanggou Bay, China represents a rare case of

Crescimento da prodissoconcha de ostras do gênero Crassostrea Sacco, 1897 (Bivalvia, Ostreidae)

open access: yesBoletim do Instituto de Pesca, 2018
Foi realizado o acompanhamento do crescimento larval de três espécies de ostras do gênero Crassostrea. As espécies Crassostrea rhizophorae (Guilding, 1828) e C. brasiliana (Lamarck, 1819) são ostras nativas do litoral do Paraná e são comercializadas nos

Resistance to OsHV-1 Infection in Crassostrea gigas Larvae [PDF]

open access: yesFrontiers in Marine Science, 2016
The ostreid herpesvirus (OsHV-1) is one of the major diseases that affect the Pacific oyster Crassostrea gigas. Selective breeding programs were recently shown to improve resistance easily to OsHV-1 infections in spat, juvenile and adult oysters. Nevertheless, this resistance has never been investigated in larvae, whereas this developmental stage has ...
