Antibiotic tolerance leads to antibiotic resistance

Membrane depolarization-triggered responsive diversification leads to antibiotic tolerance

Bacterial populations are known to harbor a small fraction of so-called persister cells that have the remarkable ability to survive treatment with very high doses of antibiotics. Recent studies underscore the importance of persistence in chronic infections, yet the nature of persisters remains poorly understood. We recently showed that the universally conserved GTPase Obg modulates persistence ...

Strategies to Combat Antibiotic Resistance

Rationalizing antibiotic use to limit antibiotic resistance in India+

Antibiotic resistance, a global concern, is particularly pressing in developing nations, including India, where the burden of infectious disease is high and healthcare spending is low. The Global Antibiotic Resistance Partnership (GARP) was established to develop actionable policy recommendations specifically relevant to low- and middle-income countries where suboptimal access to antibiotics - ...

Antibiotic Resistance

Antibiotic resistance is an ongoing evolutionary process that has been the concern of infectious disease specialists since antibiotic use gained popularity. Antibiotic resistance is not a concern of the public as reflected by their desire for antibiotics whenever illness occurs. Patients can and do pressure their physicians for antibiotics ; 12 million antibiotic prescriptions were filled for u...

Evolution of Antibiotic Resistance without Antibiotic Exposure

Antibiotic use is the main driver in the emergence of antibiotic resistance. Another unexplored possibility is that resistance evolves coincidentally in response to other selective pressures. We show that selection in the absence of antibiotics can coselect for decreased susceptibility to several antibiotics. Thus, genetic adaptation of bacteria to natural environments may drive resistance evol...
