Posted on 26/2/2017 | 446 reads | Tags: Indonesia, Health

We invite you to join us for the 10th Symposium on Diseases in Asian Aquaculture (DAA10), the popular triennial event of the Fish Health Section of the Asian Fisheries Society (FHS-AFS), to be held from 28 August to 1 September 2017 at The Anvaya Beach Resort, Kuta, Bali, Indonesia.

With the chosen theme of “Enhancing Aquatic Animal Health Research and Services through Public-Private Sector Partnerships” we anticipate to cover topics from classic parasitic, bacterial and viral diseases to emerging trends and cutting-edge research in aquatic animal health.

Three satellite workshops: FAO’s Inter-regional Workshop, NACA’s Meeting of the Asia Regional Advisory Group on Aquatic Animal Health, and a Bioinformatics Workshop are being organised back-to-back with DAA10.

The University of the Sunshine Coast, Australia, is launching a new two-year Master’s program in Applied Genetics by Research (Aquaculture) for international and national students. The program combines a coursework component with a research thesis. This innovative hybrid structure is unique in Australia as it embeds the necessary advanced and hands on discipline training integrated with tailored courses in quantitative and population genetics, reproductive biotechnologies, omics, applied statistics and bioinformatics, and analysis of breeding, genetic and genomic data.

Application for the first intake to start semester 1 (February), 2017 is now open. Further information about the program structure, admission requirements and career perspectives can be found at the University of the Sunshine Coast website.

Condolences from the network: His Majesty King Bhumibol Adulyadej

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.

A new and improved PCR detection method for Enterocytozoon hepatopenaei (EHP) based on a gene encoding a spore wall protein

Posted by Itsathitphaisarn, O., Jaroenlak, P., Sanguanrut, P., Salachan, P.V., Wiredu-Boakye, D., Williams, B.A.P., Stantiford, G.D., Flegel, T.W., Sritunyalucksana, K. | 3/7/2016 | 2581 reads | Tags: Health, Shrimp

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. canceriFrom 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).

Please download the methodology from this link.
