<em>Antibiotic resistance</em><em> is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce.</em> <u>They will then pass this trait to their offspring, which will be a fully resistant generation.</u><em><u>Restitant strains are very natural and metallic trait to their offspring.</u></em>
