Pathogenicity of Vibrio alginolyticus isolated from diseased small abalone Haliotis diversicolor supertexta.
Outbreaks of mass mortality among cultured small abalone Haliotis diversicolor supertexta with abscess/ulcers in the mantle occurred in 1998 at Kao-Hsiung, Taiwan. A swarming bacterium, strain H-11 was isolated from the haemolymph of the moribund small abalone using tryptic soy agar supplemented with 3% NaCl and/or thiosulphate citrate bile salt sucrose agar. This strain was characterized and identified as Vibrio alginolyticus on the basis of various biochemical tests. The H-11 strain and its extracellular products were virulent to small abalones with LD50 values of 3.6 x 10(5) colony forming units and 2.96 microg protein/g body weight, respectively.
