New Study Revealed Link between Global Warming and Antibiotic Resistance

Increasing temperatures are reported to accelerate antibiotic resistance in various cities across the U.S.

Antibiotic resistance was assumed to be caused due to result of over prescription and overuse. New study highlights on effects of climate change on developing antibiotic resistance. “Population growth and increases in temperature and antibiotic resistance are three phenomena that we know are currently happening on our planet,” said health researcher Mauricio Santillana. According to reported provided by hospitals across the country, MacFadden and colleagues analyzed cases of antibiotic resistance for three common bacterial strains, which include E. coli, K. pneumoniae and S. aureus.

As a part of the study, researchers compared the data with changing climatic conditions. Analysis of the data uncovered correlation between increasing local temperature, high population density, and antibiotic resistance. Furthermore, scientists stated that more research is required to identify the cause and effect relationship. Study concludes that global warming is accelerating the transmission of antibiotic-resistant organisms from one host to another, which is projected to provide more opportunities for organisms to select for resistance as they evolve and reproduce.

“The effects of climate are increasingly being recognized in a variety of infectious diseases, but so far as we know this is the first time it has been implicated in the distribution of antibiotic resistance over geographies,” said Derek MacFadden, an infectious disease specialist and research fellow at Boston Children’s Hospital, said in a news release. “We also found a signal that the associations between antibiotic resistance and temperature could be increasing over time.” The study was published in the journal Nature Climate Change in May 2018.
