Genomic diversity in flavobacterial pathogens of aquatic origin.

Flavobacterium species are considered important fish pathogens in wild and cultured fish throughout the world. They can cause acute, subacute, and chronic infections, which are mainly characterized by gill damage, skin lesions, and deep necrotic ulcerations. Primarily, three Flavobacterium species, F.

Comparative genomics of Aeromonas veronii: Identification of a pathotype impacting aquaculture globally.

Aeromonas veronii is a gram-negative species abundant in aquatic environments that causes disease in humans as well as terrestrial and aquatic animals. In the current study, 41 publicly available A. veronii genomes were compared to investigate distribution of putative virulence genes, global dissemination of pathotypes, and potential mechanisms of virulence.

Comparative Genomics of Secretion Systems and Mutational Analysis of and Genes From T6SS.

Virulent causes severe motile septicemia in warmwater fishes. In recent years, channel catfish farming in the U.S.

Draft Genome Sequence of Fish Pathogen Aeromonas bestiarum GA97-22.

is a Gram-negative mesophilic motile bacterium causing acute hemorrhagic septicemia or chronic skin ulcers in fish. Here, we report the draft genome sequence of strain GA97-22, which was isolated from rainbow trout in 1997. This genome sequence will improve our understanding of the complex taxonomy of motile aeromonads.

Comparative Analysis of the Genomovar I and II Genomes.

Columnaris disease caused by Gram-negative rod is one of the most common diseases of catfish. is also a common problem in other cultured fish species worldwide. has three major genomovars; we have sequenced a representative strain from genomovar I (ATCC 49512, which is avirulent in catfish) and genomovar II (94-081, which is highly pathogenic in catfish).

Draft Genome Sequences of Three Aeromonas hydrophila Isolates from Catfish and Tilapia.

Aeromonas hydrophila is a Gram-negative bacterium that is particularly adapted to freshwater environments and can cause severe infections in fish and humans. Here, we report the draft genomes of three A. hydrophila catfish and tilapia isolates.

Draft Genome Sequences of Four Virulent Aeromonas hydrophila Strains from Catfish Aquaculture.

Since 2009, a clonal group of virulent Aeromonas hydrophila strains has been causing severe disease in the catfish aquaculture industry in the southeastern United States. Here, we report draft genomes of four A. hydrophila isolates from catfish aquaculture that represent this clonal group.

Draft Genome Sequence of Aeromonas hydrophila TN97-08.

Aeromonas hydrophila is an opportunistic pathogen residing in freshwater environments that causes infection in fish and mammals. Here, we report the draft genome sequence of A. hydrophila strain TN97-08 isolated from a diseased bluegill (Lepomis macrochirus) in 1997.

Genome Sequence of the Fish Pathogen Flavobacterium columnare Genomovar II Strain 94-081.

Flavobacterium columnare causes columnaris disease in fresh and brackish water worldwide. F. columnare strain 94-081 was isolated from a diseased channel catfish in 1994; its genome sequence is the first completed genomovar II sequence.
