This research is testing the effectiveness of probiotics (Lactobacillus plantarum), in the control of infectious diseases in shrimp by making a quick death, disease control study on shrimp (Shrimp Early Mortality Syndrome: EMS) or a syndrome called the liver and pancreas to deteriorate suddenly (Acute Necrosis Syndrome Hepatopancreatic: AHPNS), which makes a large number of dead shrimp. This disease is caused by Vibrio parahaemolyticus (V. parahaemolyticus) and yellow head virus, infectious disease, which causes a high mortality rate up to 100 percent, which may be caused by infection Yellow head virus. Guidelines for the control of infectious diseases in Lactobacillus plantarum have led this research (L. plantarum) probiotics that have developed varieties can produce RNA to RNA gene pair cable dependent RNA polymerase (RdRp) of yellow head virus tested properties V. parahaemolyticus infection inhibits laboratory level (in vitro) Agar diffusion technique with a well, which found that L. plantarum strains that have developed the ability to still maintain a probiotic is able to inhibit growth of V. parahaemolyticus infection and L. plantarum on performance when testing the death disease in white shrimp. It is found that can resist infection, V. parahaemolyticus in prawn. However, the prevention of infectious diseases in the Pacific white shrimp, yellow head virus. Still don't see a clear protective effect. There needs to be improvement of the species plantarum, L. RNA can produce wire pair in high doses.
