Objective: We isolated bacterial strain named M-1 from ill Sciaenops ocellatus with ulceration, and further analyzed the phylogenetics of the bacterial strain.
Methods: We characterized the strain on the basis of its morphology, physiology, and sequence comparison of 16SrRNA and HSP60 genes.
Results: Strain M-1 was identified as Vibrio splendidus. 16SrRNA gene of strain M-1 and Vibrio splendidus (AJ874361) had nearest kinship, and the analysis of HSP60 gene sequence indicated that strain M-1 and Vibrio (EU653883, AY837440) located in the same phylogenetic tree.
Conclusion: The results suggested that strain M-1 was a member of Vibrio splendidus.

Introduction: The blue mussel is one of the major aquaculture species worldwide. In France, this species faces a significant threat from infectious disease outbreaks in both mussel farms and the natural environment over the past decade. Diseases caused by various pathogens, particularly spp.

Prostaglandin E2 imparts diverse physiological effects on multiple cells through its actions on four distinct E-type prostanoid (EP) receptor subtypes (EP1-EP4), among which the EP4 is one of subtypes known to mediate the immune response in mammalian monocytes and macrophages. However, the precise characteristics and functions of EP4 in mollusks remain unclear. In the present study, an EP4 homologue (designated as CgEP4) was identified from oyster Crassostrea gigas.

A number of studies have been demonstrated that arachidonate 5-lipoxygenase (ALOX-5) plays a role in regulating a range of physiological and pathological processes through the catalysis of leukotriene formation from arachidonic acid (ARA). The coding sequence of ALOX-5 from Apostichopus japonicus (Aj-ALOX-5) was successfully amplified, resulting in a 2028 bp ORF sequence that encodes 674 amino acids. A comparison of the amino acid sequence with those of other 5-lipoxygenases revealed that Aj-ALOX-5 has the N-terminal "PLAT domain" and C-terminal "lipoxygenase structural domain" characteristic of this enzyme family.

Adenine nucleotide translocator (ANT) is a major molecule in the inner membrane of mitochondria that plays an important role in regulating mitophagy. In the present study, a conserved ANT2 homologue (designated as CgANT2) was identified and functionally characterized in oyster Crassostrea gigas. There were three typical Mito_carr tandem repeats in CgANT2.
