A Vibrio anguillarum-related (VAR) strain, isolated in pure culture from an epizootic in a commercial hatchery producing Argopecten purpuratus, was characterized, and its potential pathogenicity to veliger larvae of A. purpuratus determined. Experimental challenges indicated that the bacterium affects larval survival at concentrations of 104 to 108 cells ml-l The effect of water quality and temperature on pathogenicity was also evaluated. Larval survival in seawater filtered through 5 pm pore-size membranes was 45.6%, whereas using seawater passed through 1 and 0.2 pm filters, larval survival increased to 66.4 and 80.4 % respectively. Temperature also affected pathogenicity as larval survival at 15OC for 24 h was 69.3 % but decreased to 30 and 26.9 % at 20 and 25°C respectively. Toxic activity was found in cell-free supernatant of bacterial culture. Larval survival was reduced to 68.9 and 36.4% after 20 and 40% (v/v) of supernatant, respectively, was added to the rearing water. These results suggest that exotoxins produced by the VAR strain play an in~portant role in its pathogenicity for scallop larvae.

“…Recently, Vibrio harveyi has appeared to be a primary pathogen infecting hatchery-reared fish and shellfish species over a wide geographical area (Pass et al, 1987;Pizzutto and Hirst, 1995;Vandenberghe et al, 1998;Zhang and Austin, 2000). Mortalities in hatchery-reared penaeid shrimps caused by Vibrio harveyi infection has resulted in severe economic losses in producing countries in Asia (Karunasagar et al, 1994;Lavilla-Pitogo et al, 1990;Liu et al, 1996). The lack of tools that clearly differentiate Vibrio harveyi from its phylogenetically close relatives V. campbellii, V. alginolyticus and V. parahaemolyticus (Kita-Tsukamoto et al, 1993) has hampered the rapid and accurate detection of the luminous bacterium.…”

The Vibrio harveyi hemolysin gene (vhh), which encodes for a virulence factor involved in pathogenicity to fish and shellfish species, may be targeted for species detection or strain differentiation. Primers designed for this gene were used in detection studies of V. harveyi strains from various hosts. One primer set among four tested, could amplify the expected gene fragment in PCR using templates from all 11 V. harveyi strains studied. Detection of the presence of the hemolysin gene could therefore serve as a suitable detection marker of Vibrio harveyi isolates potentially pathogenic to fish and shrimps.

“…For aquaculture industries, V. harveyi is considered as a severe opportunistic pathogen that can infect a wide range of marine species, including both vertebrates and invertebrates [1,2]. Penaeid shrimp is particularly susceptible to V. harveyi, and, upon V. harveyi infection, develops a disease called luminous vibriosis that can result in heavy economic losses [3][4][5][6][7][8]. In addition to shrimp, fish, lobster, and abalone are also known to be affected by V. harveyi-related vibriosis [9][10][11][12].…”
