A new method for the detection of AHPND-bacteria (AP4) has been published and is available for download. The advantage of the AP4 method over the previously published AP3 method is that it has 100 times higher sensitivity. Because of its higher sensitivity, the bacterial culture enrichment step needed when using the AP3 with low levels of AHPND bacteria may be omitted. However, the AP4 method should not be considered as a replacement for AP3.

Regional consultation on culture-based fisheries developments in Asia. Gender Assessment Synthesis Workshop. NACA participation in the 5th Global Symposium on Gender in Aquaculture and Fisheries, Lucknow, India. Broodstock Management in Aquaculture: Long term effort required for regional capacity building. Urgent appeal to control spread of the shrimp microsporidian parasite Enterocytozoon hepatopenaei (EHP).

Enterocytozoon hepatopenaei (EHP) is a microsporidian parasite that was first characterized and named from the giant or black tiger shrimp Penaeus monodon from Thailand in 2009. EHP is confined to the shrimp hepatopancreas (HP) and morphologically resembles an unnamed microsporidian previously reported in the HP of Penaeus japonicas from Australia in 2001. Together, these studies suggest that EHP is not an exotic pathogen but that it is endemic to Australasia.
