Results showed that the isolate is not pathogenic to Penaeus vannamei when administered orally at a dose of 106 cfu g-1 diet. Dietary supplementation for 45 days did not affect growth, reduced the gut content of V. parahaemolyticus to about five-folds and protected the shrimp against V. parahaemolyticus infection following a pathogen challenge test. Supplementation of S. hispanicus at 106 cfu g-1 diet can inhibit V. parahaemolyticus gut colonization and protects P. vannamei against this pathogen.
