Novel indigenous probiotic isolated from the healthy Pacific white shrimp Litopenaeus vannamei intestine in differing stages based on metagenomic and screening approaches.

The healthy intestinal microbiota of shrimp can be used as an indicator sustainable shrimp production. In this study, the integrated of metagenomic and screening probiotic approach from healthy Litopenaeus vannamei intestines in differing stages was studied to find novel indigenous probiotics. The microbiota from intestine of naupli, post larva (PL-10), juvenile (40 days), and adult (80 days) of Pacific white shrimp were characterized using a high-quality sequence of V3-V4 of 16S rRNA gene as the hypervariable region.

Unveiling the positive impact of biofloc culture on Vibrio parahaemolyticus infection of Pacific white shrimp by reducing quorum sensing and virulence gene expression and enhancing immunity.

This study aimed to evaluate and unveil the positive impact of biofloc culture on Vibrio parahaemolyticus infection of Pacific white shrimp by reducing quorum sensing (QS) and virulence gene expression and enhancing shrimp's immunity. The shrimp with an average body weight of 0.50 ± 0.

Dietary supplementation of Pseudoalteromonas piscicida 1UB and fructooligosaccharide enhance growth performance and protect the whiteleg shrimp (Litopenaeus vannamei) against WSSV and Vibrio harveyi coinfection.

P. piscicida 1Ub and FOS were evaluated for their potential synbiotic effects on growth, immunological responses, and disease resistance against white spot syndrome virus and V. harveyi coinfection, the major pathogen in whiteleg shrimp aquaculture.

Peptide hydrolysate from fish skin collagen to prevent and treat Aeromonas hydrophila infection in Oreochromis niloticus.

Aquaculture with an intensive system can both increase production and the disease risk. The use of antibiotics to reduce pathogens has bacterial resistance consequence. Peptides have rapidly gained more attention due to their antibacterial and immunomodulatory properties important to combat pathogens.

Immune response, gene expression, and intestinal microbial composition of Pacific white shrimp fed with multispecies synbiotic for the prevention of coinfection disease.

This study aimed to evaluate the application of synbiotic containing multispecies of probiotics with different cell densities in white shrimp rearing against infectious myonecrosis virus (IMNV) and coinfection. This study used a completely randomized design with five treatments and three replications. One additional replication of each treatment was provided for the lethal sampling.

Growth Performance and Intestinal Microbiota Diversity in Pacific White Shrimp Litopenaeus vannamei Fed with a Probiotic Bacterium, Honey Prebiotic, and Synbiotic.

This study aimed to evaluate the growth performance and intestinal microbiota composition in Pacific white shrimp after probiotic, honey prebiotic, or synbiotic treatment. Pacific white shrimp were treated for 45 days with probiotic (1% (v/w) of Bacillus sp. NP5 Rf probiotic), prebiotic (0.
