AIMS To carry out a preliminary assessment of the occurrence of resistance to antimicrobials in bacteria that has been isolated from a variety of aquaculture species and environments in Australia. METHOD AND RESULTS A total of 100 Gram-negative (Vibrio spp. and Aeromonas spp. predominantly) and four Gram-positive bacteria isolated from farmed fish,(More)
A total of 129 Pseudomonas spp. and 90 Aeromonas spp. were isolated from nine rainbow trout (Oncorhynchus mykiss) farms in Australia. All the isolates were tested for sensitivity to 15 antibiotics and the multiresistant strains were tested for sensitivity to seven heavy metals. Minimal inhibitory concentrations (MICs) were determined by the agar dilution(More)
AIMS To determine the genetic determinants responsible for tetracycline resistance in oxytetracycline resistant bacteria from aquaculture sources in Australia. METHODS AND RESULTS Twenty of 104 (19%) isolates tested were resistant to oxytetracycline (MIC > or = 16 microg ml(-1)). Using polymerase chain reaction (PCR) amplification, one or more tet genes(More)
