pseudovibrio pseudovibrio in taxonomy, pseudovibrio is a genus of the hyphomicrobiales. bacteria belonging to this genus have been often isolated from marine invertebrates and have been described to be metabolically versatile. recent comparative genomic analyses revealed that these organisms have the genomic potential to produce a great array of systems to interact with their hosts, including type iii, iv, vi secretion systems and different type of toxin-like proteins. moreover, in their genomes several biosynthetic gene clusters producing potentially novel bioactive compounds were recently identified. pseudovibrio scientific classification domain: bacteria phylum: pseudomonadota class: alphaproteobacteria order: hyphomicrobiales family: stappiaceae genus: pseudovibrioshieh et al. 2004 species pseudovibrio ascidiaceicola fukunaga et al. 2006 pseudovibrio axinellae o'halloran et al. 2013 pseudovibrio denitrificans shieh et al. 2004 pseudovibrio exalbescens (donachie et al. 2006) hördt et al. 2020 pseudovibrio hongkongensis xu et al. 2015 pseudovibrio japonicus hosoya and yokota 2007 pseudovibrio stylochi zhang et al. 2016 synonyms nesiotobacter donachie et al. 2006 "polycladidibacter" hinger et al. 2020
