Resumen
Las poblaciones bacterianas tienen la habilidad de adaptarse rápida y óptimamente a los cambios en los ambientes en los que existen. De esta manera, en ambientes propicios, con ausencia o baja incidencia de factores estresantes, se las puede encontrar de forma individual, también llamada planctónica. Sin embargo, los cambios bruscos en el ambiente que las rodea, conducen a un cambio importante en el comportamiento de la bacteria individual, la cual tiende a contactar y “comunicarse” con las bacterias aledañas para conformar una patina bacteriana, llamada biofilm. Los biofilm son responsables de las infecciones bacterianas crónicas y/o recidivantes en humanos y animales. La característica fundamental de los biofilm bacterianos es su amplia resistencia frente a una variedad de antimicrobianos, la cual es consecuencia de mecanismos distintos a los reportados para la bacteria en estado planctónico. La formación de biofilms comienza a ser reconocida como un proceso de desarrollo multicelular. Esta es la llave de las nuevas estrategias terapéuticas: el cambio del blanco a tratar, dejar de pensar en la bacteria para empezar a pensar en ese organismo multicelular conformado por bacterias al que se denomina biofilm.
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.
