Vibrio harveyi is amongst the most important bacterial pathogens in aquaculture. Novel methods to control this pathogen are needed since many strains have acquired resistance to antibiotics. We previously showed that quorum sensing-disrupting furanones are able to protect brine shrimp larvae against vibriosis. However, a major problem of these compounds is(More)
OBJECTIVES Staphylococcus epidermidis is often associated with biofilm infections related to medical implants. The aim of the present study was to find furanones that decrease biofilm formation without irritative or genotoxic effects, or effects on S. epidermidis growth. METHODS After screening including bioluminescence and biofilm assays, 2 furanones out(More)
AIMS To study a possible effect of a synthetic brominated furanone on biofilm formation and biofilm resistance to disinfectants in Salmonella enterica. METHODS AND RESULTS The effect of a synthetic furanone on biofilm formation of Salm. enterica serovar Agona and Salm. enterica serovar Typhimurium (11 strains of different origins) was evaluated in a(More)
AIMS Investigate the use of a synthetic brominated furanone (F202) against the establishment of biofilm by Salmonella ser. Agona and E. coli O103:H2 under temperature conditions relevant for the food and feed industry as well as under temperature conditions optimum for growth. METHODS AND RESULTS Effect of F202 on biofilm formation by Salmonella ser.(More)
Disease caused by antibiotic resistant pathogens is becoming a serious problem, both in human and veterinary medicine. The inhibition of quorum sensing, bacterial cell-to-cell communication, is a promising alternative strategy to control disease. In this study, we determined the quorum sensing-disrupting activity of 20 thiophenones towards the quorum(More)
Interference with bacterial quorum sensing communication provides an anti-virulence strategy to control pathogenic bacteria. Here, using the Enteropathogenic E. coli (EPEC) O103:H2, we showed for the first time that thiophenone TF101 reduced expression of lsrB; the gene encoding the AI-2 receptor. Combined results of transcriptional and phenotypic analyses(More)
