Antibiotic resistance of Vibrio species isolated from Sparus aurata reared in Italian mariculture.
Extensive use of antimicrobial agents in finfish farming and the consequent selective pressure lead to the acquisition of antibiotic resistance in aquaculture environment bacteria. Vibrio genus represents one of the main pathogens affecting gilthead sea bream. The development of antibiotic resistance by Vibrio represents a potential threat to human health by exchange of resistant genes to human...
متن کاملCymothoid isopod parasites in aquaculture: a review and case study of a Turkish sea bass (Dicentrarchus labrax) and sea bream (Sparus auratus) farm.
This paper reviews the occurrence of cymothoid isopod parasitism in aquaculture, reports the first case of infection by a cymothoid isopod (Ceratothoa oestroides) in Turkish aquaculture, and analyses its effects on sea bass Dicentrarchus labrax. Analyses revealed that C. oestroides negatively affects the weights and lengths of sea bass hosts. These effects have been previously underestimated be...
متن کاملStimulation of gut immune system by early administration of probiotic strains in Dicentrarchus labrax and Sparus aurata.
Early feeding (started during gut metamorphosis and establishment of the hypothalamic-pituitary-interrenal axis) with probiotic-supplemented diets, besides modifying the intestinal microflora, evoked profound effects on the physiology of fish larvae. Using rotifers and Artemia as living vectors, the autochthonous bacterium Lactobacillus delbrueckii delbrueckii or a multispecies probiotic formul...
متن کاملPreliminary Study on the In vitro and In vivo Effects of Asparagopsis taxiformis Bioactive Phycoderivates on Teleosts
Several compounds from marine organisms have been studied for their potential use in aquaculture. Among the red algae, Asparagopsis taxiformis is considered one of the most promising species for the production of bioactive metabolites with numerous proposed applications. Here, the in vitro antibacterial activity, the easy handling and the absence of adverse effects on marine fish species are re...
متن کاملThe ability of marine Bacillus spp. isolated from fish gastrointestinal tract and culture pond sediment to inhibit growth of aquatic pathogenic bacteria
In this research, antagonistic activity of two Bacillus species isolated from digestive tract of marine fish and culture pond of sea cucumber was studied. The inhibitory activity of Bacillus spp. isolates against some common pathogenic bacteria of fish was assessed using the agar diffusion method. The strain of B. subtilis G024 exhibited antimicrobial activity against Vibrio anguillarum, V. har...
