Evolution of antibiotic resistance in E. coli studied

  • It is well known that low concentrations of antibiotics  can cause resistance to evolve among bacteria.
  • Now, a group of researchers from IISER Pune have  studied how resistance to the antibiotic rifampicin  evolves in E.
  • coli under two conditions — when the  antibiotic is present in low or high concentrations, and  when there is steady or pulsed supply of antibiotics.
  • According to the study, the process of evolution of  drug resistance appears to be rapid.
