The coral bleaching Vibrio shiloi Kushmaro et al. 2001 is a later synonym of Vibrio mediterranei Pujalte and Garay 1986

The coral bleaching Vibrio shiloi LMG 19703T was characterized by means of Fluorescent Amplified Fragment Length Polymorphism (FAFLP), DNA-DNA hybridisation, mol% G+C content, fatty acids methyl ester (FAME) analysis and phenotypical tests. Numerical analysis of the FAFLP band patterns indicated that the type strain of V. shiloi in fact belongs to the species V. mediterranei. The type strains of both species shared 77% DNA similarity, as determined by DNA-DNA hybridisation experiments at stringent conditions. Moreover, V. shiloi and V. mediterranei showed almost identical fatty acid composition and phenotypical features. Collectively, the genotypic and phenotypic data presented in this study suggest that V. shiloi Kushmaro et al. 2001 should be considered a later synonym of V. mediterranei Pujalte and Garay 1986. The involvement of V. mediterranei in coral bleaching was unknown until now.
