Antibiotics, Volume 9, Issue 1

2020 January - 38 articles

Cover Story: Biofilms play an important role in infectious diseases. It has been estimated that 60% to 70% of nosocomial infections are caused by the formation of a biofilm. Historically, microalgae have been an important source of bioactive compounds with novel structures with an important potential biological role in, among others, the food, animal feed, aquaculture, cosmetics, and pharmaceutical industries. Several studies have described compounds with antimicrobial activity isolated from microalgae and cyanobacteria species. However, studies about the antibiofilm activity of extracts and/or molecules produced by these microorganisms are scarce. Quorum-sensing inhibitor and anti-adherent agents have, among others, been isolated from microalgae and cyanobacteria species. The use of tools such as nanotechnology increase their power of action and can be used to prevent and treat biofilm-related infections. View this paper
