摘要: Abstract Postlarval and juvenile stages of four species western hemisphere penaeid shrimp (Penaeus aztecus, P. duorarum, setiferus, vannamei) were experimentally challenged with white spot syndrome virus (WSSV) yellow head (YHV) isolates originating from Asia. Challenge exposures accomplished by feeding minced tissue WSSV- or YHV-infected tissues. The WSSV challenge postlarval resulted in severe infections setiferus vannamei less aztecus duorarum. (∼1 g) 100% cumulative mortality vannamei, moderate 27% no signs infection 0% YHV caused serious disease juveniles all species, but appeared resistant to because virus-related infection, mortality, di...
