The randomly amplified polymorphic DNA (RAPD) technique was used to analyse the genetic differentiation of 13 strains of Aeromonas salmonicida subsp. salmonicida, and seven strains of Aer. hydrophila. Reproducible profiles of genomic DNA fingerprints were generated by polymerase chain reaction (PCR) using a single randomly designed primer. The RAPD profiles(More)
A literature review on the use of live microorganisms as probiotics is presented. Topics discussed are the definition of probiotic; the normal microflora of the digestive system of mammals, including bacterial interactions in the gut, colonization, modification of metabolic processes, and immunostimulation. Probiotics studies in humans and in farmed(More)
Yellowtail Seriola quinqueradiata were immunized with 2 different Lactococcus garvieae bacterin, formalin-killed KG- phenotype cells (capsulated phenotype) and formalin-killed KG+ phenotype cells (unencapsulated phenotype). These 2 injected vaccines conferred long-term protection to yellowtail against an artificial infection of an encapsulated Lactococcus(More)
Virulence factors were compared in Aeromonas species isolated from clinically normal and septicaemic farmed frogs from Thailand. Haemolysin activities against frog erythrocytes were significantly different within the collection of aeromonads. Groups of high haemolytic activity (unspeciated Aeromonas, Au), moderate haemolytic activity (A. hydrophila), and(More)
A group of seven sucrose-negative Aeromonas strains (referred to as group Au) isolated from the internal organs of septicaemic farmed frogs (Rana rugulosa) in Thailand was subjected to a polyphasic taxonomic study including fluorescent amplified fragment length polymorphism (FAFLP) and ERIC-PCR fingerprinting, 16S rDNA sequencing, microplate DNA-DNA(More)
The effectiveness of the delivery of amoxicillin to Atlantic salmon, undergoing chemotherapy in natural outbreaks of furunculosis in sea-cages, was investigated by measuring the concentration of the drug in serum samples. Five groups of 50 sera from three outbreaks were collected two hours after oral treatment with doses of 80 or 120 mg/kg bodyweight.(More)
This paper briefly reviews the use of chemicals to prevent and treat bacterial diseases in aquaculture, and provides a detailed summary of the current state of knowledge on the development of bacterial resistance to antimicrobial agents in fish and shellfish. The topics covered include mechanisms of resistance, resistance of bacterial fish pathogens,(More)
In N1E 115 neuroblastoma cells, gamma-dendrotoxin (DTX, 200 nM) blocked the outward K(+) current by 31.1 +/- 3.5% (n = 4) with approximately 500 nM Ca(2+) in the pipet solution, but had no effect on the outward K(+) current when internal Ca(2+) was reduced. Using a ramp protocol, iberiotoxin (IbTX, 100 nM) inhibited a component of the whole cell current,(More)
The effect of combination of trimethoprim with other non-sulphonamide antibacterial agents, in particular oxolinic acid and nalidixic acid, was evaluated against Gram-negative fish pathogens. The species included Aeromonas salmonicida, Yersinia ruckeri, some Vibrio spp. and Escherichia coli as a reference. The extent of synergy found by other workers with(More)
