K.‐K. LEE, S.‐R. YU, T.‐I. YANG, P.‐C. LIU AND F.‐R. CHEN. 1996. Outbreaks of serious mortality among cultured kuruma prawns ( Penaeus japonicus ) with white spotted syndrome in the carapace occurred in the summer of 1993 in I‐Lan, Taiwan. A swarming bacterium, strain Swy, was isolated from the hepatopancreas of the moribund prawns using tryptic soy agar supplemented with 1% NaCl and/or thiosulphate citrate bile salt sucrose agar. This strain was characterized and identified as Vibrio alginolyticus on the basis of a number of biochemical tests. The Swy strain was virulent to both kuruma prawns ( P. japonicus ) and tiger prawns ( P. monodon ) with LD 50 values of 4.43 times 10 4 and 1.57 times 10 5 cfu g body weight ‐1 , respectively.
