In a major breakthrough, researchers at the University of Arizona have identified the causative agent behind "shrimp early mortality syndrome" or EMS, more accurately known as acute hepatopancreatic necrosis syndrome.

The causative agent is a strain of a bacteria commonly found in brackish water, Vibrio parahemolyticus, with possible involvement of a phage.

For the full story, please see the press release on the FAO website.

Very encouraging news. Congratulations to Dr Lightner's team and all that have assisted with the search for the culprit - Ed.
