Edwardsiella tarda is an important pathogen for fish. The strain NCIMB 2034, obtained from the National Collection of Industrial Food and Marine Bacteria, was isolated from unknown diseased fish in the United States. The draft genome sequence has 3.79 Mb with a G+C content of 57.1% and >3,340 protein-coding genes.

The majority of bacteria found within the gut are commensals, although it is unclear whether these organisms can elicit systemic immunity. New research indicates that gut-microbiota-specific serum antibodies targeting an epitope conserved among Gram-negative bacteria can protect the host from systemic pathogenic infection.

Tetragenococcus muriaticus strains 3MR10-3 and PMC-11-5 are homofermentative halophilic lactic acid bacteria isolated from Thai fish sauce during natural fermentation. Their draft genomes were sequenced. Our interest in these organisms is related to their impact on fish sauce flavor and their high osmotolerance.

Histamine-producing bacteria are responsible for scombrotoxin (histamine) fish poisoning, a leading cause of fish poisoning in the United States. We report here the draft genome sequences of four histamine-producing (HP) Photobacterium kishitanii strains and nine HP Photobacterium angustum strains isolated from tuna.

Viruses were recognized as the causative agents of fish diseases, such as infectious pancreatic necrosis and Oregon sockeye disease, in the early 1960s [1], and have since been shown to be responsible for diseases in all marine life from bacteria to protists, mollusks, crustaceans, fish and mammals [2].[...].

Three strains of gliding bacteria resembling a known fish pathogen, Flexibacter columnaris, were recently isolated from diseased freshwater fishes in France. Morphological, physiological, and biochemical characteristics were very similar to those of 6 F. columnaris strains previously identified in other countries and used here for reference. This is the first unequivocal identification of this ...

the effects of dietary supplementation of garlic (allium sativum)extract on the growth and disease resistance of african catfish, clarias gariepinus was evaluated. also in-vitro evaluation of susceptibility of fish-borne multidrug resistant (mdr) pathogenic bacteria to aqueous extract of garlic was done. aqueous garlic extract exhibited inhibitory activity against mdr bacteria and the degree of...

This study was conducted to determine the effect of different salinities on striped catfish (Pangasianodon hypophthalmus) susceptibility hemorrhagic disease causing by Aeromonas hydrophila bacteria. The experiment set up in plastic tanks at various (0, 3, 5, 8, 11 and 14‰). Experimental fish (about 25 ± 0.8g/fish) were challenged with A. bacteria intramuscular injection. After infection, mortal...

The antibacterial activities of the essential oil of Eucalyptus globulus (EOEG) was determined against 7 fish pathogenic bacteria (Edwardsiella tarda, Streptococcus iniae, S. parauberis, Lactococcus garviae, Vibrio harveyi, V. ichthyoenteri and Photobacterium damselae) obtained from farmed olive flounder. The inhibitory activity was evaluated by three methods: Disc diffusion method, minimum inh...

Fish skin mucus contains several immune substances that provide the first line of defence against a broad spectrum of pathogens although they are poorly studied to date. Terminal carbohydrate composition and levels of total IgM antibodies, several immune-related enzymes (lysozyme, peroxidase, alkaline phosphatase, esterases, proteases and antiproteases) as well as the bactericidal activity (aga...
