请问马修博士是怎么看待EMS的啊?
EMS = Early Mortality Syndrome
Early mortality syndrome can be caused by a number of different pathogenic, environmental and management issues. Some, but not all of this appears to be caused by a new and previously unknown syndrome called Acute Hepatopancreatic Necrosis Syndrome (AHPNS)
In Vietnam sampling has shown only 50% of EMS is caused by AHPNS (the rest is WSSV and other problems)
In Thailand – the figures are <30% caused by AHPNS
could you be specific so i can answer?
Cause unknown for 4 years, but this month, Dr. Lightner from Arizona, working with Flegal in Mahidol and FAO/ NACA/World Bank finally identified causative agent as a specific strain of Vibrio parahaemolyticus transmitted orally & colonizing intestine |
