In vitro antibacterial activity of Peganum harmala (L) extract to some fish pathogenic bacteria
This study was conducted to examine in vitro antibacterialpotential from seed methanol extract of Peganum harmala (L) against some fish pathogenic bacteria including Lactococcus garvieae, Aeromonas hydrophila, Yersinia ruckeri and Pseuodomonas putida isolated from diseased rainbow trout (Oncorhynchus mykiss). The antibacterial activity of extracts was evaluated using disc diffusion assay, m...
متن کاملTemperature-dependent expression of virulence genes in fish-pathogenic bacteria
Virulence gene expression in pathogenic bacteria is modulated by environmental parameters. A key factor in this expression is temperature. Its effect on virulence gene expression in bacteria infecting warm-blooded hosts is well documented. Transcription of virulence genes in these bacteria is induced upon a shift from low environmental to a higher host temperature (37°C). Interestingly, host te...
متن کاملAntibacterial Activity of Marine Sponge Extracts against Fish Pathogenic Bacteria
Secondary metabolites of the marine sponges Acanthella elongata, Axinella donnani, Callyspongia diffusa, Callyspongia subarmigera, and Echinodictyum gorgonoides were collected from fishing nets and their in vitro antibacterial properties against eight virulent marine fish pathogens were studied at incubation temperatures of 20°C and 30°C. Crude methanol extracts of the tested sponges showed spe...
متن کاملTransferable drug resistance plasmids in fish-pathogenic bacteria
Chemotherapeutic agents have been developed for treating bacterial infections and have been widely used for cultured fish for the last 30 years in Japan. The extensive use of chemotherapeutants has resulted in an increase in the occurrence of drug resistance in fish-pathogenic bacteria and also in the bacterial flora of the intestinal tract of cultured fish. The kinds of chemotherapeutants used...
متن کاملAntimicrobial Effect of Lactic Acid Bacteria against Common Pathogenic Bacteria
Abstract Background and Objective: Probiotics are living microorganisms that have beneficial effects on the health of digestive system. The aim of this study was to evaluate the antimicrobial ability of acidic and neutral supernatants (culture supernatant) of lactic acid bacteria against common bacterial pathogens. Meth...
