Abstract
    The genomic diversity among 506 strains of the family Vibrionaceae was analysed using Fluorescent Amplified Fragments Length Polymorphisms (FAFLP). Isolates were from different sources (e.g. fish, mollusc, shrimp, rotifers, artemia, and their culture water) in different countries, mainly from the aquacultural environment. Clustering of the FAFLP band patterns resulted in 69 clusters. A majority of the actually known species of the family Vibrionaceae formed separate clusters. Certain species e.g. V. alginolyticus, V. cholerae, V. cincinnatiensis, V. diabolicus, V. diazotrophicus, V. harveyi, V. logei, V. natriegens, V. nereis, V. splendidus and V.tubiashii were found to be ubiquitous, whereas V.halioticoli, V.ichthyoenteri, V.pectenicida and V. wodanis appear to be exclusively associated with a particular host or geographical region. Three main categories of isolates could be distinguished: (1) isolates with genomes related (i.e. with 45% FAFLP pattern similarity) to one of the known type strains; (2) isolates clustering (45% pattern similarity) with more than one type strain; (3) isolates with genomes unrelated (<45% pattern similarity) to any of the type strains. The latter group consisted of 236 isolates distributed in 31 clusters indicating that many culturable taxa of the Vibrionaceae remain as yet to be described.
