Biofilms bacterianos
Keywords:
Bacteria planctónica, Resistencia antimicrobiana, Infecciones bacterianas, Infecciones bacterianas crónicas, BiofilmAbstract
Bacterial populations have the ability to adapt quickly and optimally to changes in its environment. Thus, in favourable environments, with no or low incidence of stressors, they can be found in individual form also called planktonic. However, sudden changes in the surrounding environment leads to a significant change in the behaviour of the individual bacteria, which tends to contact and “communicate” with neighbour bacteria to form a conglomerate called biofilm. Biofilms are responsible for chronic/recalcitrant infections in humans and animals. The most important feature of bacterial biofilms is their high resistance to a wide range of antimicrobials, by mechanism other than those reported for planktonic bacteria. Biofilms development is beginning to be recognized as a process of multicellular development. This is the key to a new therapeutic strategy: changing the therapeutic target from the planktonic bacteria to this multicellular organism called biofilm.
