A total of 481 samples, including 417 shrimp and molluscan shellfish samples from retail shops and farms and 64 water samples from shrimp and molluscan shellfish farms in the Mekong Delta located the southern part of Vietnam, were examined for the presence of () caused acute haepatopancreatic necrosic disease (AHPND) in shrimp. strains were isolated in two of 298 (0.7%) molluscan shellfish samples from retail shops, seven of 71 (9.9%) shrimp samples from shrimp ponds, and two of 42 (4.8%) water samples from shrimp ponds. strains were classified into two types of O antigen, including O1 and O3, in which O1 was the predominant. strains isolated showed high resistance rates to colistin (100%), ampicillin (93.8%), and streptomycin (87.5%). These results indicate that is widely prevalent in environment in the Mekong Delta, Vietnam.
共检测了481份样本，其中包括来自越南南部湄公河三角洲零售商店和养殖场的417份虾和贝类样本，以及来自虾和贝类养殖场的64份水样，以检测是否存在导致虾急性肝胰腺坏死病（AHPND）的（某种物质）。在来自零售商店的298份（0.7%）贝类样本中的两份、来自虾塘的71份（9.9%）虾样本中的七份以及来自虾塘的42份（4.8%）水样中的两份中分离出了（该物质）菌株。（该物质）菌株被分为两种O抗原类型，包括O1和O3，其中O1占主导。分离出的（该物质）菌株对黏菌素（100%）、氨苄青霉素（93.8%）和链霉素（87.5%）显示出高耐药率。这些结果表明（该物质）在越南湄公河三角洲的环境中广泛流行。
