Short description

The resistome refers to the totality of genes in a specific habitat or microbial community that can confer antibiotic resistance.

Detailed description

One example is the resistome of the human gut. It comprises the various resistance genes present in the microorganisms found there. Some of these genes can be transferred between bacteria and thereby contribute to the spread of antibiotic resistance.

The composition of the resistome can change over time. In particular, the use of antibiotics can give bacteria with certain resistance genes a survival advantage, thereby promoting their spread. Studying the resistome helps researchers better understand the emergence and spread of antibiotic resistance.
