Use of Direct-Fed Microbes To Enhance Shrimp Resistance to a Vibrio Parahaemolyticus Strain Causing Early Mortality Syndrome
… attributed to pathogenic Vibrio parahaemolyticus strains (VP-EMS). This disease threatens aquaculture production and global food security. A valuable and alternative approach to using antibiotics for pathogen control, is the practice of incorporating direct-fed microbes (DFM) or probiotics. In …

The Influence of Prebiotics, Probiotics, and Exposure to an Opportunistic Pathogen on the Intestinal Microbiome of White Shrimp (Litopenaeus vannamei)
Prebiotics and probiotics, proposed alternatives to antibiotics in shrimp aquaculture, are reported to improve growth parameters, promote disease resistance, and influence the gut microbial community. This study aimed to investigate the influence of prebiotic- or probiotic-coated feed and/or …
