This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Antimicrobial resistance (AMR) is an increasingly serious threat to global public health. New resistance mechanisms reduce our ability to treat common infectious diseases. Although microorganisms possessing AMR genes are thought to have emerged from natural habitats, better understanding is needed. A new study sought to examine the consequences of introducing antimicrobials into natural environments. Using lichen – a model for well-defined micro-ecosystems consisting of hundreds of microbial species – researchers evaluated changes in microbial communities following exposure to different antimicrobials. They found that the native lichen microbiome comprises highly diverse and low-abundance intrinsic antimicrobial resistance genes (ARGs) to cope with antimicrobial pressure. Antimicrobial-specific shifts occurred in the structure and function of the microbiome following 10 days of exposure to antimicrobials..."
