Effect of and B10 on gut microbiota modulation in broilers.

The gut microbiota plays important roles in animal overall health and productiveness. Balancing host gut microbiota by probiotics has been documented. Our previous study showed that () and B10 () significantly improve growth performance and modulate the intestinal histomorphology in broilers.

Impact of BL23 on the Host Transcriptome, Growth and Disease Resistance in Larval Zebrafish.

In this study, zebrafish were treated with strains as probiotics from hatching to puberty, and the effect of treatment with BL23 on the development and immunity response of the host was investigated. Genes that were differentially expressed (DEGs) in the overall body and intestine were detected at 14 days post fertilization (dpf) and 35 dpf, respectively, using whole transcriptome sequencing (mRNAseq). We showed that zebrafish raised by continuous immersion with BL23 showed a higher final body weight at 14 dpf ( < 0.

Aeromonas veronii and aerolysin are important for the pathogenesis of motile aeromonad septicemia in cyprinid fish.

Aeromonas species are ubiquitous inhabitants of freshwater environments, and are responsible for fish motile aeromonad septicemia (MAS). A. hydrophila is implicated as the primary etiologic agent of MAS.

EPSP of BL23 Protected against the Infection Caused by via Enhancement of Immune Response in Zebrafish.

Aquaculture is the fastest-growing food production sector in the world, and it supplies nearly 50% of the global food fish supply. However, disease outbreaks have become a major problem in the fish farming industry. The beneficial contribution of probiotic bacteria to aquatic animals' health has been widely described, and they have been widely used in aquaculture for disease control and growth promotion.

Anti-Infective Effect of Adhesive Probiotic Lactobacillus in Fish is Correlated With Their Spatial Distribution in the Intestinal Tissue.

In this study, we tested the distribution of 49 Lactobacillus strains in the mucus and mucosa of the intestine tissue of zebrafish. We observed a progressive change in the spatial distribution of Lactobacillus strains, and suggested a division of the strains into three classes: mucus type (>70% in mucus), mucosa type (>70% in mucosa) and hybrid type (others). The hybrid type strains were more efficient in protection of zebrafish against Aeromonas hydrophila infection.

Effects of chito-oligosaccharides supplementation on growth performance, intestinal cytokine expression, autochthonous gut bacteria and disease resistance in hybrid tilapia Oreochromis niloticus ♀ × Oreochromis aureus ♂.

We investigated the effects of incorporating chitinase (ChiB565)-hydrolyzed shrimp shell chitin into the diet of hybrid tilapia (Oreochromis niloticus ♀ × Oreochromis aureus ♂) with regard to production, intestinal immune status and autochthonous gut bacteria, and protection against bacterial pathogen Aeromonas hydrophila. Five experimental diets were formulated by supplementing the basal diet with the hydrolyzed shrimp shell chitin (0.0%, T1 control; 0.

Comparison of fecundity and offspring immunity in zebrafish fed Lactobacillus rhamnosus CICC 6141 and Lactobacillus casei BL23.

To increase the knowledge of probiotic effects on zebrafish (Danio rerio), we compare the effects of two probiotic strains, Lactobacillus rhamnosus CICC 6141 (a highly adhesive strain) and Lactobacillus casei BL23 (a weakly adhesive strain), on zebrafish reproduction and their offsprings' innate level of immunity to water-borne pathogens. During probiotics treatments from 7 to 28 days, both the Lactobacillus strains, and especially L. casei BL23, significantly increased fecundity in zebrafish: higher rates of egg ovulation, fertilization, and hatching were observed.

High-yield production of a chitinase from Aeromonas veronii B565 as a potential feed supplement for warm-water aquaculture.

Chitin, present in crustacean shells, insects, and fungi, is the second most plentiful natural organic fiber after wood. To effectively use chitin in a cost-saving and environmentally friendly way in aquaculture, crustacean shells (e.g.
