Abstract

Six Gram-negative coccobacilli were isolated from Pacific oysters () from Mexico and haemolymph of spider crabs () from Spain. All of the isolates grew as small green colonies on thiosulphate-citrate-bile salts-sucrose (TCBS) agar and were facultatively anaerobic, oxidase-positive and sensitive to the vibriostatic agent O/129. Repetitive palindromic PCR analysis revealed a high degree of genomic homogeneity among the isolates. Several phenotypic traits differentiated the isolates from the type strains of species of the genus . DNA–DNA relatedness between two representative isolates and their closest phylogenetic neighbours by 16S rRNA gene sequence similarity, CAIM 14 and CAIM 20, was 44.01–53.85 %. We propose a novel species of the genus to accommodate the six isolates, with the name sp. nov. The type strain is CAIM 1393 (=CECT 7576).
