2009. Characterisation of antibiotic resistance gene clusters and their mobility within a collection of multi-drug resistant Salmonella spp. Xiulan Liu. University of
The possibility that unexpressed antibiotic resistance genes are carried by bacterial genomes is seldom investigated. Potential silencing of the resistance genes
One can say, yes, in the United States there are dominant patents on the use of antibiotic resistance genes for the selection of transformed plants. That means, it
There has probably been a gene pool in nature for resistance to antibiotic as long as For example, antibiotic-resistance genes of staphylococci are carried on
Antibiotic resistance is a type of drug resistance where a microorganism is able to survive exposure to an antibiotic. While a spontaneous or induced genetic
Antibiotic Resistance Gene (ARG) maintenance: Aerobic versus anaerobic conditions and the correlation of plasmid loss to the intracellular redox environment
Researchers in Hong Kong have identified an identical gene in both humans and animals for antibiotic resistance.
Will antibiotic resistance marker genes (ARG) used in the development of GM crops increase the occurrence of antibiotic resistant bacteria? The use and
The mission of the ARGD is to provide a centralized compendium of information on antibiotic resistance, facilitate the consistent annotation of resistance
Plasmids are DNA molecules, usually circular, that are independent of the chromosomal DNA. In bacteria these can replicate independently as well. In genetic
Sewage treatment plants (STPs) are considered as important reservoirs for antibiotic resistance genes (ARGs) and activated sludge characterized with high
Alternatives to antibiotic marker genes have been developed. Methods like herbicide resistance, nutritive selection, visible markers, and marker gene removal
To understand how resistance genes enable bacteria to survive an attack by an antibiotic, it helps to know exactly what antibiotics are and how they harm
The end of the antibiotic miracle is not a new theme. The genes that confer carbapenem resistance have appeared over the past decade or
