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.
