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.»

The genes encoding NDM - 1 and other antibiotic resistance factors are usually carried on plasmids — circular strands of DNA separate from the bacterial genome — making it easier for them to spread through populations.

Bacteria can become resistant to the antibiotic either as the result of a spontaneous mutation or by picking up an appropriate «resistance gene» (which codes for a protein that confers resistance) from another bacterium via genetic exchange.

Scientists have known for a while that phages are able to transduce genes but this was considered a rare event for genes encoding resistance to antibiotics.

Researchers will also want to find out whether bacterial integrons of other species can also pick up genes besides those for antibiotic resistance.

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.

So for example, if one microbe is resistant to antibiotics and the other one isn't, if we let them have sex, maybe one of them will pass the resistance gene on to the other one and we can figure out where it is by seeing how long it takes for that gene to get from one microbe to the other.

Into some bacteria they inserted genes for resistance to particular antibiotics; the idea is that only the antibiotic - resistant bacteria are carrying the real message.
