Chemotaxis of pathogenic Vibrio strains towards mucus surfaces of gilt-head sea bream (Sparus aurata L.).
نویسندگان
چکیده
Vibrio anguillarum and Vibrio alginolyticus exhibited significant adhesion to and chemotactic abilities towards mucus collected from the skin, gills, and intestine of gilt-head sea bream. Quadratic polynomial models for chemotaxis designed to estimate the influence of temperature demonstrated a differential bacterial chemotaxis depending of the source of the mucus, with the chemotaxis towards intestinal mucus being the least influenced.

Pathogenicity of Vibrio alginolyticus for cultured gilt-head sea bream (Sparus aurata L.).
The in vivo and in vitro pathogenic activities of whole cells and extracellular products of Vibrio alginolyticus for cultured gilt-head sea bream were evaluated. The 50% lethal doses ranged from 5.4 x 10(4) to 1.0 x 10(6) CFU/g of body weight. The strains examined had the ability to adhere to skin, gill, and intestinal mucus of sea bream and to cultured cells of a chinook salmon embryo cell lin...

Four bacterial isolates from farmed gilthead sea bream, Sparus aurata, included in a previous study as members of the Vibrionaceae and Pseudomonodaceae and the genus Micrococcus, have been evaluated for their adhesive ability to skin and intestinal mucus of farmed Senegalese sole, Solea senegalensis, and their antagonistic effect on Vibrio harveyi, a pathogen of sole. These isolates showed high...

Vibrio renopiscarius DCR 1-4-2(T) (CECT 8603(T)) and DCR 1-4-12 (CECT 8604) were isolated from healthy gilthead sea bream (Sparus aurata) from Mediterranean fish farms (Castellón, Spain). Their draft genome sequences (30 and 44 contigs, respectively) have 4.3 Mbp and a G+C content of 45.2 mol% and contain almost 3,700 protein-encoding genes.
متن کاملIsolation and characterization of a fish F-type lectin from gilt head bream (Sparus aurata) serum.
A novel fucose-binding lectin, designated SauFBP32, was purified by affinity chromatography on fucose-agarose, from the serum of the gilt head bream Sparus aurata. Electrophoretic mobility of the subunit revealed apparent molecular weights of 35 and 30 kDa under reducing and non-reducing conditions, respectively. Size exclusion analysis suggests that the native lectin is a monomer under the sel...
