Effects of potential probiotic Bacillus subtilis T13 on growth, immunity and disease resistance against Vibrio splendidus infection in juvenile sea cucumber Apostichopus japonicus.

A feeding experiment was conducted to determine influences of potential probiotic Bacillus subtilis T13 (isolated from intestine of healthy sea cucumbers) on growth, immunity and disease resistance against Vibrio splendidus infection in juvenile sea cucumbers Apostichopus japonicus. Animals were fed with diets containing B. subtilis T13 at 0, 10(5), 10(7) and 10(9) CFU/g for 30 days, respectively.

Effects of dietary n-3 highly unsaturated fatty acids on growth, nonspecific immunity, expression of some immune related genes and disease resistance of large yellow croaker (Larmichthys crocea) following natural infestation of parasites (Cryptocaryon irritans).

The study was conducted to investigate the effects of dietary n-3 highly unsaturated fatty acid (n-3 HUFA) on growth, nonspecific immunity, expression of some immune related genes and disease resistance of juvenile large yellow croaker (Larmichthys crocea) following natural infestation of parasites (Cryptocaryon irritans). Six isoproteic and isolipidic diets were formulated with graded levels of n-3 HUFA ranging from 0.15% to 2.

Transcriptional up-regulation of a novel ferritin homolog in abalone Haliotis discus hannai Ino by dietary iron.

A novel cDNA encoding ferritin (HdhNFT) was cloned from the hepatopancreas of abalone, Haliotis discus hannai Ino. The deduced protein contains 171 amino acid residues with a predicted molecular mass (MW) about 19.8 kDa and theoretical isoelectric point (pI) of 4.

Interaction of dietary Bacillus subtilis and fructooligosaccharide on the growth performance, non-specific immunity of sea cucumber, Apostichopus japonicus.

A feeding experiment was conducted to investigate the interaction of probiotic Bacillus subtilis and prebiotic fructooligosaccharide (FOS) on the growth performance, immunity, intestinal microflora and disease resistance of sea cucumber (Apostichopus japonicus). Five hundred and forty individuals (initial body weight: 5.06 +/- 0.

Molecular cloning, characterization and mRNA expression of selenium-dependent glutathione peroxidase from abalone Haliotis discus hannai Ino in response to dietary selenium, zinc and iron.

A novel selenium-dependent glutathione peroxidase (Se-GPX) was cloned from abalone Haliotis discus hannai Ino (HdhGPx) by homology cloning with degenerate primers and RACE techniques. The full length of HdhGPx cDNA was 963bp with a 669bp open reading frame (ORF) encoding 222 amino acids and a 101bp eukaryotic selenocysteine insertion sequence (SECIS) in 3' untranslated region (UTR). It was showed that HdhGPx has a characteristic codon at (235)TGA(237) that corresponds to selenocysteine (SeC) as U(72).

Effects of dissolved oxygen on survival and immune responses of scallop (Chlamys farreri Jones et Preston).

This experiment investigated the effects of dissolved oxygen (DO) on the survival and immune responses of scallop Chlamys farreri. The scallops (initial mean dry weight of soft tissue 1.52+/-0.

Effects of dietary pyridoxine on immune responses in abalone, Haliotis discus hannai Ino.

A feeding experiment was conducted to investigate the effects of dietary pyridoxine (PN) on the immune responses of abalone, Haliotis discus hannai Ino. Purified diets supplemented with 0, 40, 800 mg PN kg(-1) or 80 mg kg(-1) of 4-deoxypyridoxine (PN antagonist) were fed to adult abalone (initial weight 45.77 +/- 0.
