Resistance of bacteria to antibiotics

Most of the bacterial presents varying degrees of antibiotic resistance acquired by mechanisms such as genetic variability, decreased permeability to the drug, its enzymatic inactivation and chemical modification the target on serving.

The manual resistance not only is transmitted from generation to generation between the same species of bacteria, but can spread to different strains through the transfer of resistance genes.

This makes a bacterium that is immune to an antimicrobial drug with which it had never before contacted.
