Detection protocol of EMS in shrimp released to avoid new outbreaks

A group of scientists from universities and research centres in Thailand and Taiwan, supported by National Agencies have been successful in developing a detection method for early mortality syndrome (EMS) in shrimp, and decided the free release of primers and protocols for the public use in order to curb the disease outbreaks, the National Centre for Genetic Engineering and Biotechnology (Biotec) informed.
The disease was initially called early mortality syndrome, (EMS) but this general designation caused confusion due to other causes of early mortality, and the more precise name of acute hepatopancreatic necrosis syndrome (AHPNS) was recommended.
The paper points out the current economic situation in the shrimp culture industry in Asia, which is critical and daily losses due to direct shrimp mortality or due to suspended cultivation, are enormous. In the recent past, the average production of cultivated shrimp in Thailand has been in the range of 30-50 thousand metric tonnes monthly. At a farm-gate value of approximately THB 100 to 200 (USD 3-6) per kg, this amounts to THB 3,000-5,000 million (USD 90.7 -151.1 millon) per month and THB 100-167 million (USD 3-5 millon) per day.
They believe that every single day of reduction in the risk of AHPND outbreaks will benefit Thailand far in excess of any possible return on research expenditures that might be envisioned by collection of royalties for their discoveries.
Therefore, they have decided to release, free for public access, detailed information on the sequences and protocols from their research for a polymerase chain reaction (PCR) detection method for AHPND bacteria. This will allow interested stakeholders to assess the efficacy in developing possible measures to reduce the risk of AHPND outbreaks.
