High mortality among laboratory cultured Iberian toothcarp Aphanius iberus occurred in February 1997 in Valencia (Spain). The main signs of the disease were external haemorrhage and tail rot. Bacteria isolated from internal organs of infected fish were biochemically homogeneous and identified as Vibrio parahaemolyticus. The bacteria were haemolytic against erythrocytes from eel Anguilla anguilla, amberjack Seriola dumerili, toothcarp A. iberus and humans, and were Kanagawa-phenomenon-negative. Infectivity tests showed that the virulence for A. iberus was dependent on salinity. Finally, all strains were virulent for amberjack and eel.
1997年2月，西班牙巴伦西亚实验室养殖的伊比利亚齿鲤（Aphanius iberus）出现了高死亡率。该病的主要症状为体表出血和尾鳍腐烂。从患病鱼的内脏器官分离出的细菌在生化特性上具有同质性，经鉴定为副溶血性弧菌。这些细菌对欧洲鳗鲡（Anguilla anguilla）、黄条鰤（Seriola dumerili）、伊比利亚齿鲤和人类的红细胞具有溶血活性，且神奈川现象呈阴性。感染性试验表明，该菌对伊比利亚齿鲤的毒力取决于盐度。最后，所有菌株对黄条鰤和鳗鲡都具有毒性。
