Spread of tetracycline resistance genes at a conventional dairy farm
The use of antibiotics in animal husbandry contributes to the worldwide problem of increasing antibiotic resistance in animal and human pathogens. Intensive animal production is considered an important source of antibiotic resistance genes released to the environment, while the contribution of smaller farms remains to be evaluated. Here we monitor the spread of tetracycline resistance (TC-r) ge...
متن کاملAntimicrobial resistance at farm level.
Bacteria that are resistant to antimicrobials are widespread. This article reviews the distribution of resistant bacteria in farm environments. Humans, animals, and environmental sites are all reservoirs of bacterial communities that contain some bacteria that are susceptible to antimicrobials and others that are resistant. Farm ecosystems provide an environment in which resistant bacteria and ...
متن کاملDetection of tetracycline resistance genes in bacteria isolated from fish farms using polymerase chain reaction
Five common tetracycline resistance genes tet(A), tet(B), tet(M), tet(O) and tet(S) were studied by polymerase chain reaction in 100 bacteria isolated from Iranian fish farms. In the antibiogram test most of the bacteria were either intermediately or completely resistant to tetracycline. Nine isolates out of 46 Aeromonas spp. contained eithe...
متن کاملMilk Quality and Antimicrobial Resistance against Mastitis Pathogens after Changing from a Conventional to an Experimentally Organic Dairy Farm
The present study was to investigate the effect of the transition from conventional to organic dairy farming on the antimicrobial resistant pattern of pathogens in milk. A farm with tie-stall management, with an average herd size of 20 milking cows, was selected based on the owner’s willingness to accept, for at least 6 months, the highly restricted protocol developed in this study. Comparisons...
متن کاملGlobal Spread of Multiple Aminoglycoside Resistance Genes
Emergence of the newly identified 16S rRNA methylases RmtA, RmtB, and ArmA in pathogenic gram-negative bacilli has been a growing concern. ArmA, which had been identified exclusively in Europe, was also found in several gram-negative pathogenic bacilli isolated in Japan, suggesting global dissemination of hazardous multiple aminoglycoside resistance genes.
