Sentences with phrase «genes for antibiotic resistance in»

The answer is that it forms the platform for illuminating the interaction between the use of animal manure and the appearance of genes for antibiotic resistance in soil.

Examining E. coli bacteria, which are responsible for about 80 % of urinary tract infections, the researchers found an identical gene for antibiotic resistance in both humans and animals.

Not exact matches

Over the past 60 years, genes for antibiotic resistance have gone from rare to commonplace in the microbes that routinely infect our bodies.

«You've got the genes encoding for resistance in the soil beneath these operations,» he says, «and we know that the majority of the antibiotics animals consume get excreted intact.»

One reservoir for resistance genes where they can be exchanged among bacteria — and possibly end up in the food chain — is the sediment in marine fish farms even when no antibiotics have been applied.

From isolated caves to ancient permafrost, antibiotic - resistant bacteria and genes for resistance have been showing up in unexpected places.

Rudich and his team then explored the genes in these bacteria, checking for antibiotic resistance — a trait that can arise owing to elevated use of antibiotics but also naturally, especially in soil bacteria.

Collected in Denmark — where antibiotics were banned in agriculture from the 1990s for non-therapeutic use — the soil archives provide an «antibiotic resistance timeline» that reflects resistant genes found in the environment and the evolution of the same types of antibiotic resistance in medicine.

However, as Wilson explains: «The genes necessary for resistance are often activated only when required (i.e., when the antibiotic is present in the environment), and so - called leader or signal peptides play an important role in this process.»

While antibiotic resistance genes are not harmful in themselves, they limit the use of antibiotics for treating bacterial infections and pose a serious threat to global public health if they get transmitted to humans from environmental sources, such as compost.

The scientists have also detected resistance genes for sulphonamides and another antibiotic in the treated wastewater — which will be turned into snow at a nearby ski resort, in a relatively pristine part of a river basin, later this year.

That background makes it important to characterize «both the natural occurrence of the antibiotic - resistance genes and the anthropogenic load, and where those genes come from, and it's good to do it in a quantitative way,» as Pruden's team did for the South Platte, says Joakim Larsson of the University of Gothenburg, Sweden, who has tracked antibiotics and resistance genes in India and Sweden.

Though well - known pathogens weren't seen in abundance, the presence of genes for antibiotic resistance, resistance to water disinfectants and virulence raises concerns because bacteria can share such genes to potentially become more significant health threats.

«If mcr - 1 is present in India then that will be a disaster,» says Ghafur, who fears it will spread as fast as did genes for resistance to another antibiotic of last resort, carbapenem.

Conjugation is the main route for horizontal gene transfer in bacteria and is responsible for the spread of antibiotic resistance.

An assessment of the risks associated with the use of antibiotic resistance genes in genetically modified plants: report of the Working Party of the British Society for Antimicrobial Chemotherapy.

The team, reporting its work in Nature Nanotechnology doi: 10.1038 / s41565 -017-0029-3, says that it is now busy further developing tools for metagenomics - based risk assessment — in particular with respect to antibiotic - resistance genes and their relation to environmental stressors.

To characterize the resistome in detail we searched the metagenomes for signatures of known antibiotic resistance genes.

Significant differences in abundances were found for several resistance genes associated with resistance to several classes of antibiotics, including sulfonamides, fluoroquinolones and aminoglycosides (Figure 2 and Tables S12, S13, S14, S15, S16).

In this manner, copies of genes that code for antibiotic resistance can be passed around, and the recipients can reproduce themselves at a furious rate, further propagating the gene.
