TL;DR: Dietary L. plantarum administration at 10(8) cfu kg(-1) is recommended to promote growth and enhance immunity and resistance against Streptococcus sp.

TL;DR: Results of this study showed that feeding non-vaccinated and vaccinated carp with combination of Astragalus and Ganoderma stimulated respiratory burst activity, phagocytosis ofphagocytic cells in blood and lysozyme and circulatory antibody titres in plasma in vaccinated carp.

TL;DR: The results suggest that the increased resistance of shrimp after B. subtilis E20 consumption occurs through immune modifications, such as increases in phenoloxidase activity, phagocytic activity, and clearance efficiency against V. alginolyticus.

TL;DR: Evidence is provided that early feeding with probiotic-supplemented diet stimulated the larval gut immune system and lowered transcription of key pro-inflammatory genes in fish.

TL;DR: Micrococcus luteus and Pseudomonas species isolated from the gonads and intestine of Nile tilapia, Oreochromis niloticus enhanced the fish growth and health and showed probiotic effects in vitro only.

TL;DR: The results suggest that the shrimp immune response could be activated or inhibited by different PAMPs, and that the hepatopancreas also plays a key role by synthesizing immune factors.

TL;DR: The aim of this review is to update recent knowledge of innate immunity against viral infections in crustaceans by identifying and characterization of several antiviral molecules isolated and characterized recently from decapods.

TL;DR: The maintenance of the brood stock immunity at high level during vitellogenesis and oogenesis, is utmost important for reducing mortalities at larval/post larval stages through maximum/optimum transfer of maternal immunity.

TL;DR: The present study measured the changes in the level of important immunological parameters such as prophenoloxidase, superoxide dismutase and superoxide anion in hemolymph of chitosan-encapsulated VP28 DNA-treated and controls shrimp and correlated the changes with the survival percentage and protective efficacy.

TL;DR: Results reveal that a two-week feeding regime with Kocuria SM1 leads to higher disease protection in rainbow trout, with protection linked to stimulation of immune parameters.

TL;DR: Zebrafish larval survival was assessed following treatment with various types of LPS at a variety of concentrations to determine the sensitivity of zebrafish to LPS-induced immune activation, and an inhibitory role for CXCR4 in the inflammatory cascade was supported.

TL;DR: The propolis-ethanolic-extract enhanced the growth, immunity and resistance of O. niloticus against A. hydrophila more than the crude propolis, and was high with T(2) and T(3).

TL;DR: It is indicated that all the doses of ethanol or methanol triberbal solvent extracts could be positively influence the immune response and protect the heath status of goldfish against A. hydrophila infection.

TL;DR: Bacteria were able to modulate the haemocytes' respiratory burst activity and nitric oxide production and mytilin B, myticin C and lysozyme gene expression and, among all assayed PAMPs, LPS elicited the highest response.

TL;DR: Investigation of the effect of beta-glucan on the immune response and its protection against an infection of the bacterial pathogen Aeromonas hydrophila in zebrafish found it modulated IFNgamma and chemokine expression in kidney and enhanced the ability of kidney cells to kill A. hydrophILA.

TL;DR: Dietary intake containing A. membranaceus root or its polysaccharides could enhance the immune responses of A. japonicus and improve its resistance to infection by Vibrio splendidus.

TL;DR: Results indicated that as a universal key adaptor in the Toll-like receptor pathway in mammals, MyD88 might play an important role in large yellow croaker defense against pathogenic infection.

TL;DR: Results suggested that FcLec3 might function in the recognition of bacterial and viral pathogens in shrimp.

TL;DR: In this paper, the identification and functional analysis of a Relish homologue, LvRelish and its shorter isoform sLvRelish, from the Pacific white shrimp, Litopenaeus vannamei, was described.

TL;DR: Testing the efficacy of the antimicrobial peptide LFB in fish aquacultures suggests that medaka fish fed with the LFB-containing transgenic microalgae will have bactericidal defense against V. parahaemolyticus infection in its digestive tract.

TL;DR: Investigation of immunological activities and morphology of hemocytes of the Suminoe oyster using flow cytometry and light microscopy revealed that the granulocytes are most active in the cell phagocytosis and spontaneous reactive oxygen species (ROS) production.

TL;DR: It is concluded that the expression of pro- and anti-inflammatory cytokines in the seabream head kidney is highly influenced by stress-related hormones, thus indicating an important role for the endocrine system in the modulation of the immune response in teleost fish.

TL;DR: The results indicate that propolis and Herba Epimedii extracts in combination enhances the non-specific immune response and disease resistance of Chinese sucker against A. hydrophila.

TL;DR: A significant up-regulation of all three pro-inflammatory cytokines was found in the gills, which were the site of parasite attachment, and allow for more detailed investigations of the striped trumpeter immune response.

TL;DR: The ability of Bio-Mos to improve the survival, health status and immunity of marron under the bacterial infection and stress conditions caused by air and NH3 exposures was demonstrated.

TL;DR: The GCHV-infected group pre-treated with beta-glucan had a higher survival rate (60%) than the group not pre- treated with Beta-Glucan (20%), suggesting that beta- glucan possesses or enhances anti-viral responses.

TL;DR: The results indicate that L. vannamei hemocyanin has a novel function with hemolytic activity, partly related to a colloid-osmotic mechanism mediated by its oligomers and revealed that the hemolysis could be inhibited to different degrees by osmoprotectants with high molecular masses, suggesting that it follows a colloids-osMotic mechanism.

TL;DR: It is considered that the extracts of stout camphor tree could be a candidate to replace the chemo-therapeutants through the inhibitory effects against the growth of pathogens, and enhanced effects on shrimp immunity and disease resistance.

TL;DR: Increases in lipopolysaccharide and beta-1,3-glucan-binding protein of hemocytes and the hepatopancreas, and respiratory bursts per cell, and a decrease in superoxide dismutase were found in viral-infected shrimp, which may have been related to the defense against viral infection.

TL;DR: Quantitative reverse transcriptase PCR assays were developed to systematically profile all of the rainbow trout IFN transcripts, with high specificity at an individual gene level, in naïve fish and after stimulation with virus or viral-related molecules and will be useful for future studies aimed at identifying which cells produce IFNs at early time points after infection.
