New research reveals extensive prevalence of antibiotic resistance in bacteria that was previously unknown.

The abundance of latent and established antibiotic-resistant genes (ARGs) was analyzed using principal component analysis in various environments including aquatic, plants, infants, wastewater, terrestrial, human, birds, and mammals. The study, published in Microbiome by Swedish researchers from Chalmers University of Technology and the University of Gothenburg, found that ARGs are more prevalent in bacteria in all environments than previously thought. The study analyzed 630 billion DNA sequences, identifying new forms of resistance genes in various environments, such as sewage treatment plants, soil, and even the human microbiome. This presents a serious threat to global health, as antibiotic-resistant bacteria are difficult to treat. The researchers recommended a focus on enhancing understanding of the development of resistance in bacteria through risk assessments relating to antibiotic resistance.
