Widespread, occasional use of antibiotics in US linked with resistance

The study also found that antibiotic use varies across the nation, and that in areas where particular antibiotics are used more frequently, resistance to those antibiotics is higher.

"We know that efforts to reduce inappropriate use of antibiotics are critical to addressing the problem of antibiotic resistance. We wondered whether every antibiotic prescription contributes equally to resistance, and whether, as some previous research has suggested, the most effective way to minimize antibiotic resistance would be to focus on the small fraction of people who use most of the antibiotics," said Yonatan Grad, Melvin J. and Geraldine L. Glimcher Assistant Professor of Immunology and Infectious Diseases and senior author of the study. "Our results show that most antibiotic use is occasional -- by people taking just one antibiotic course in a year -- and that this occasional use is more closely linked with antibiotic resistance than intense, repeated use."

Study - December - ELife - Look - Link

The study was published online December 18, 2018 in eLife. It is the first to take a population-wide look at the link between distribution of antibiotic use and resistance to those antibiotics.

Antibiotic resistance has risen to dangerously high levels in recent years, spurred by over-prescription and overuse. Infections such as gonorrhea, tuberculosis, and foodborne diseases are becoming harder, and sometimes impossible, to treat as antibiotics become less effective, according to the World Health Organization (WHO).

Study - Researchers - Home - Distribution - Use

In the new study, researchers sought to home in on how the distribution of antibiotic use impacts antibiotic resistance. They used data sources that allowed them to simultaneously analyze antibiotic use and resistance for an unprecedented number of antibiotics and pathogens....
