Insight Into Biofilms Could Change Our Relationship With Bacteria

Bacteria, those tiny, often-misunderstood microorganisms, have just gave up a groundbreaking secret that could transform our approach to combating infections.  

Bacteria are notorious for banding together and forming biofilms. Biofilms are complex communities of these organisms that stick to each other and various surfaces, ranging from medical devices to industrial equipment. This mode of living not only makes them incredibly resilient but also challenges our efforts to eliminate them when they contaminate critical surfaces. Things get even more concerning when pathogenic bacteria are involved, as they pose a serious threat to human health. So, understanding how bacteria regulate their ability to form these communities is paramount. 

Thanks to a recent discovery led by Dr. José Eduardo González-Pastor from the Centro de Astrobiología (CAB), CSIC-INTA, we can imagine a world where we could prevent biofilms on medical devices like catheters or industrial equipment, protect against bacterial infections, and even gain new insights into the human microbiome.
