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...
متن کاملChemotaxis of pathogenic Vibrio strains towards mucus surfaces of gilt-head sea bream (Sparus aurata L.).
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 i...
متن کاملVibrio renipiscarius sp. nov., isolated from cultured gilthead sea bream (Sparus aurata).
Two strains of Gram-negative, facultatively anaerobic, slightly halophilic bacteria, isolated from healthy gilthead sea bream (Sparus aurata) cultured in Spanish Mediterranean fish farms, were different from their closest relatives, Vibrio scophthalmi and V. ichthyoenteri, by phenotypic, phylogenetic and genomic standards. The strains were negative for decarboxylase tests and lacked extracellul...
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...
متن کاملVaccination of Silver Sea Bream (Sparus sarba) against Vibrio alginolyticus: Protective Evaluation of Different Vaccinating Modalities
In order to develop more effective immunological strategies to prevent vibriosis of farmed marine fish in Hong Kong and southern China, various vaccine preparations including formalin-, phenol-, chloroform- and heat-killed whole cell bacterins and subcellular lipopolysaccharides (LPS), as well as different administration routes, were investigated. Fish immunized with the subcellular LPS exhibit...
