Sewage measures global levels of antimicrobial resistance

❝ A comprehensive analysis of sewage collected in 74 cities in 60 countries has yielded the first, comparable global data, which show the levels and types of antimicrobial resistant bacteria that are present in mainly healthy people in these countries. The National Food Institute, Technical University of Denmark, headed the study, which was conducted by an international team of researchers.

❝ In a metagenomics study, the researchers have mapped out all the DNA material in the sewage samples and found that according to antimicrobial resistance the world’s countries fall within two groups. North America, Western Europe, Australia and New Zealand generally have the lowest levels of antimicrobial resistance, while Asia, Africa and South America have the highest levels.

Brazil, India and Vietnam have the greatest diversity in resistance genes, while Australia and New Zealand have the lowest…

❝ According to the researchers, the use of antimicrobials only explains a minor part of the occurrence of antimicrobial resistance in the various countries…Their work shows that most of the variables, which are associated with the occurrence of antimicrobial resistance in a country, are related to the sanitary conditions in the country and the population’s general state of health.

Nothing startling. Still, worth keeping your brain – and behavior – up to date on news about a growing problem.

    “Food safety: Dung beetles and soil bacteria reduce risk of human pathogens” (British Ecological Society 3/19/19) https://www.eurekalert.org/pub_releases/2019-03/bes-fsd031519.php “New research published today in the Journal of Applied Ecology encourages the presence of dung beetles and soil bacteria at farms as they naturally suppress E. coli and other harmful pathogens before spreading to humans. …To study how this may aid food safety, the entomologist drove a van full of pig feces along the US West Coast to follow the planting of broccoli at 70 farm fields during the growing season. Broccoli, much like leafy greens, is susceptible to fecal contamination due to its proximity to the ground and the likelihood of humans consuming it without cooking.
    Dung beetles likely kill harmful bacteria when they consume and bury the feces. Previous research also suggested that these beetles have antibiotic-like compounds on their body.”

    “Pathogenic, drug-resistant bacteria found in wastewater treatment plants” (Cold Spring Harbor Laboratory Press 3/21/19) https://www.eurekalert.org/pub_releases/2019-03/cshl-pdb031419.php “In a study published today in Genome Research, researchers conducted a survey of 20 municipal wastewater plants in England, and isolated drug-resistant E. faecium from all sites in both untreated and treated wastewater plants except three, which use ultraviolet light disinfection. Importantly, drug-resistant E. faecium counts were significantly higher in untreated wastewater from plants that were direct recipients of hospital sewage. A genomic comparison of E. faecium isolates from wastewater and bloodstream isolates of infected patients revealed two major lineages, with ampicillin-resistant bacteria in clade A1 and A2 and vancomycin-resistant bacteria exclusive to clade A1. Further genetic analysis revealed the presence of shared antibiotic, metal, and biocide resistance genes in clade A1 isolates from bloodstream, hospital sewage, and municipal wastewater.”
