New Strategy Against Resistant Bacteria Prevents Formation of Protective Biofilm

Bacteria are experts at evolving resistance to antibiotics. One resistance strategy is to cover their cell walls in sticky and gooey biofilm that antibiotics cannot penetrate. A new discovery could put a stop to this strategy.

Understanding How Bacteria Share Antibiotic Resistance

A study provides new clues in the understanding of how antibiotic resistance spreads. The study shows how an enzyme breaks down the bacteria's protective outer layer, the cell wall, and facilitates the transfer of genes for resistance to antibiotics.
