Strength in numbers: How biofilms outfox antibiotics
When bacteria flock together and form a community, this is called a biofilm. Found all over the planet — from desert rocks to the surfaces of buildings — biofilms are an integral part of nature.
Biofilms are tricky beasts because they have a tendency to become resistant to all manner of efforts employed to eradicate them. This spells bad news for anyone with conditions such as cystic fibrosis, periodontitis, or chronic wounds as medical implants and catheters are hotspots for biofilm formation.
But why are biofilms so persistent, and what are doctors and scientists doing to outsmart these clever microbial communities?
What are biofilms?
“Biofilms are one of the most widely distributed and successful modes of life on Earth,” says Prof. Hans-Curt Flemming — director of the Institute for Interface Biotechnology at the University of Duisburg-Essen in Germany — in a 2016 article published in Nature Reviews Microbiology.
