Abstract

Vibrio tapetis strain 6087 was isolated, in association with atypical Aeromonas salmonicida, from moribund Atlantic halibut, Hippoglossus hippoglossus. The 16S rRNA gene sequence of strain 6087 showed only one base difference from the strain CECT 4600T in 1472 residues. Biochemically, the strain was similar to reference strains of V. tapetis (CECT 4600T, IS1, IS5 and UK6). Cluster analysis based on reactions in BIOLOG GN plates showed strain 6087 to cluster within the V. tapetis group and to be more closely related to strains CECT 4600T and IS1 than to IS5 or UK6. Despite the above similarities, strain 6087 differed from reference strains in being able to utilise mannitol and being unreactive with antiserum to V. tapetis IS1. As these two tests are used routinely in the identification of V. tapetis it is possible that this organism is more widely distributed than previously thought and consists of more than one serotype. However, strain 6087 did not induce overt signs of brown ring disease in Manila clams, Tapes philippinarum or overt disease in juvenile Atlantic halibut.
