Biopelículas microbianas y su impacto en áreas médicas: fisiopatología, diagnóstico y tratamiento

: Biofilms are communities of microorganisms that grow aggregated and surrounded by an extracellular matrix, which they produce and favors them to adhere covalently to inert and living surfaces; it also helps them to develop high tolerance to molecules with antimicrobial activity. Moreover, biofilms are associated with chronic and persistent infections, which negatively impact different medical areas since they generate high costs to health care systems and patients every year because they are difficult to treat with conventional antimicrobial drugs. Additionally, they generate high rates of morbidity and mortality. The objective of this review was to present extensive and up-to-date information on the origin, biosynthesis, and pathophysiology of biofilms. Also, its relationship with chronic infections, diagnosis, current antimicrobial treatments with antibiotic activity, and perspectives on the search for new treatments, since the latter still represent an important area of research.
