WF-Shield White Fecal Management

White Feces Syndrome (WFS) is an emergent disease of penaeid shrimp (Penaeus monodon and P. vannamei) that is identified by the presence of floating white fecal strings on pond water in grow-out ponds. Although the clinical manifestations of WFS are well defined, the underling etiology remains obscure. WFS in P. vannamei pre-infected with EHP and challenged with a unique isolate of Vibrio parahaemolyticus isolated from the gastrointestinal tract of a shrimp displaying WFS. There is limited information on specific immune mechanisms provided by the shrimp gut microbiota there are evidences of its interplay with the digestive activities that directly affect shrimp growth and severity of diseases. New emerging diseases were found to target the shrimp hepatopancreas causing growth inhibition, size disparity, loss of appetite and chronic mortality.

Approach of using carbon quantum dots (CQDs) doped with essential oils represents an innovative strategy in enhancing antibacterial efficacy through synergistic effects. Carbon quantum dots are nanoscale carbon-based particles that exhibit unique properties like high surface area, good biocompatibility, which make them excellent carriers and enhancers for bioactive compounds. When combined with essential oils, these properties of CQDs help improve the antibacterial potential of essential oils through several mechanisms. WF SHIELD utilizes synergism between Carbon Quantum Dots (CQDs) doped essential oils to potentiate antibacterial activity by 20-40 times.

These essential oils based activated phytochemicals are potentiated further with ELVITATM technology which are the Quantum Herbal Nanoinfused (QHN) nanoparticles with the help of Phytosomes, potentiated herbal biomolecule for its efficacy. Phytosomes are a promising delivery system for enhancing the intracellular uptake of essential oils, which may improve their effectiveness against vibrio.

Silver, copper, and zinc nanoparticles present a promising solution for controlling White Fecal Disease in shrimp. By providing antimicrobial, immune-boosting, and gut health benefits, these nanoparticles support shrimp health and production efficiency. We have used silver nanoparticles, copper nanoparticle and zinc nanoparticles & IgY antibodies to control Vibriosis. Silver nanoparticles (AgNPs) have strong broad-spectrum antimicrobial effects. They can inhibit bacterial growth by disrupting cell membranes, binding to bacterial DNA, and generating reactive oxygen species (ROS). AgNPs are particularly effective against Vibrio species. Copper nanoparticles (CuNPs) have bactericidal and antifungal properties that are beneficial in managing bacterial infections in shrimp. CuNPs disrupt the bacterial cell wall and interfere with microbial enzyme function, leading to cell death. Zinc nanoparticles (ZnNPs) also exhibit antimicrobial properties and play a role in immune enhancement. They interfere with bacterial metabolism and protein synthesis, which can help control gut pathogens that cause White fecal disease. The antimicrobial action of these nanoparticles can reduce harmful bacterial loads in the shrimp gut, supporting a healthier microbiome.

Fructooligosaccharides (FOS), Mannan oligosaccharides (MOS), and Vitamin E are increasingly used in aquaculture to help control diseases, including White Fecal Disease (WFD) in shrimp. WFD, often associated with bacterial pathogens like Vibrio species, affects gut health and overall shrimp well-being. These components work by supporting gut health, strengthening immunity, and reducing pathogen load, helping to manage WFD effectively. At the same time Selenium nanoparticles, Vitamin E to boost immune system of shrimp. This helps to control bacterial and associated other infectious agents and help to improve productivity. In addition, chelated minerals, vitamins and growth promotors helps to improve recovery from disease.
