Bacteria and fungi are well-known for evolving resistance to antibiotics (levy 1998), but are thought to be less likely to evolve resistance to biocides because these compounds often act by different mechanisms. Antibiotic resistant bacteria are usually harmless and go undetected antibiotic resistance genes alone do not cause pathogenicity organisms today carry high loads of antibiotic resistance determinants in their microbiota – this is not illness, but an evolved condition of bacterial populations exposed to antibiotics in increasing amounts. Mutations causing antibiotic resistance are often associated with a cost in the absence of antibiotics surprisingly, a new study found that bacteria adapting to increased temperature became resistant to rifampicin by studying the consequences of the involved mutations in different conditions and.
