On behalf of the network, the NACA Secretariat would like to express our profound condolences to the people of Thailand regarding the passing of His Majesty King Bhumibol Adulyadej. The world's longest serving monarch, His Majesty King Bhumibol reigned for more than 70 years.
His Majesty was reknowned for his personal involvement in and commitment to development for the people of Thailand and the region, establishing his first rural development project in Huai Mongkol village of Hua Hin in 1952. In 2006 he was presented with the first UNDP Human Development Lifetime Achievment Award by United Nations Secretary-General Kofi Annan.
He was, and will remain, a guiding light and a role model for us all.
NACA's Director General Dr Cherdsak Virapat was interviewed on the "Around the World" radio programme of Saranrom (AM 1575 kHz), concerning the mission and role of NACA in regional food security. Please note the interview is in Thai language.

Hepatopancreatic microsporidiosis (HPM) caused by Enterocytozoon hepatopenaei (EHP) is a newly emerging disease of cultivated shrimp in Asia. Current evidence indicates that it can be associated with severe growth retardation that may not be clearly evident until the second month of culture and that it may even cause low continuous mortality in the case of very severe infections.
Here we present a new method for detecting Enterocytozoon hepatopenaei (EHP) that has superior specificity to the first generation SSU-PCR developed in 2009 when the genetic information of EHP was still limited. Due to the urgency in stemming losses to HPM, we have decided to release this method for free, non-commercial use to the global shrimp farming community.
The second generation EHP detection method presented here is based on a gene encoding a spore wall protein (SWP) of EHP (SWP-PCR). Results from our laboratory work revealed, in contrast to SSU-PCR, that the SWP-PCR method did not give cross reactions with DNA from crabs infected with H. eriocheir and E. canceri. From these results, we recommend that the new SWP-PCR method replace the first generation SSU-PCR method.
The sequences of the primers for the SWP-PCR method (nested PCR) are given below and can be used freely for non-commercial applications to detecting EHP. Please contact Centex Shrimp (ornchuma.its 'at' mahidol.ac.th) to obtain a free positive control plasmid (pGEM-EHPSWP).
Prizes include: Power banks, fitness watches, USB sticks and t-shirts

The Second International Technical Seminar/Workshop on AHPND: There is a way Forward! will be held from 23-25 June 2016 at the Sukosol Hotel in Bangkok, Thailand.
The purpose of the meeting is to update knowledge and exchange experiences in dealing with AHPND, to validate current concepts and models under different systems and environmental conditions and to put into action the responsibilities of the different sectors (i.e. government, producer and academe) as a way forward to deal with AHPND.
The meeting will consist of three technical sessions looking at EMS/AHPND through the lens of the industry, the academe and the government sectors and a fourth session on the way forward.
All interested stakeholders are welcome to attend. A catering fee of US$40 / day applies (includes lunch plus morning and afternoon tea). Reservations will be accepted until close of business on 10 June; places are limited.
