One of the major threats to seabass (Dicentrarchus labrax) aquaculture sector is development vibriosis, a disease caused mainly by bacteria from family Vibrionaceae, especially Vibrio harveyi. Given relationship between abundance in surrounding environment and prevalence fish, monitoring presence V. harveyi rearing water biofilms over time may help better understand dynamics pathogen factors th...

The use of effective biocides as disinfectants is essential in aquaculture facilities. However, while most act effectively on free-living planktonic pathogens, they are seldom useful against biofilms. In this study, we evaluate the biocidal efficacy and antimicrobial specific contact time three disinfectants, Virkon™Aquatic (VirA), peracetic acid (PerA) hydrogen peroxide (HydP), Vibrio anguilla...

The antigenicity of Photobacterium damselae (Ph. d.) subsp. piscicida, cultured in four different growth media [tryptone soya broth (TSB), glucose-rich medium (GRM), iron-depleted TSB (TSB + IR(-)), and iron-depleted GRM (GRM + IR(-))] was compared by enzyme-linked immunosorbent assay (ELISA) and Western blot analysis using sera obtained from sea bass (Dicentrarchus labrax) raised against live ...

To the Editor: In a letter recently published in Emerging Infectious Diseases, Smith (1) discussed evidence that he mistakenly believes to undermine the hypothesis that the fl orfenicol resistance gene present in some isolates of the epidemic Salmonella enterica serovar Typhimurium DT104 strain originated from a fl orfenicol resistance plasmid present in Vibrio damsela (Pasteurella piscicida) t...

Cantharidin, a toxic monoterpene secreted by blister beetles, has long been used in traditional Chinese and modern medicine for its unique properties. However, despite widespread use, effects on fish have not studied. The aim of this study was to evaluate the potential therapeutic applications cantharidin examining antioxidant, hemagglutinating, hemolytic, cytotoxic activities at different conc...
