What to do about EMS/AHPN?

Ideally, farmers need to create conditions that make it harder for the pathogenic Vibrio that causes AHPN to colonize animals’ stomachs and for the toxin to produce its pathology. Exclusion where possible and appropriate management of ecosystems offer hope in

AHPN inferences based on behavior of vibrio bacteria

Vibrio parahaemolyticus, a strain of which is the cause of acute hepatopancreatic necrosis (AHPN), has both virulent and benign strains. This strain colonizes the stomachs of shrimp by the formation of a biofilm, which protects it from antibiotics and other
