Although plausible, definite evidence for such direct selection in sewage treatment plants is still lacking, and some evidence points to the opposite69. Although we agree with the principle, we believe that other abiotic and biotic factors that determine the survival of most pathogens in environmental media, and hence exposure opportunities, are likely to be of much greater importance for transmission risks (see the section entitled Environmental transmission).

Surveillance of antimicrobial resistance in Europe 2017 (Stockholm, Sweden, 2018). (p. 300) Kills 1.5 million children worldwide each year It is thus conceivable that small growth differences between resistant and non-resistant strains, caused by exposure to sub-MICs of antibiotics, are a minor determinant for the possibility that environmental exposure becomes sufficiently high for colonization or infection of a human or animal host. D. Acute inflammatory response. The Global action plan on antimicrobial resistance has 5 strategic objectives: A political declaration endorsed by Heads of State at the United Nations General Assembly in New York in September 2016 signalled the worlds commitment to taking a broad, coordinated approach to address the root causes of antimicrobial resistance across multiple sectors, especially human health, animal health and agriculture. https://doi.org/10.3389/fmicb.2011.00158 (2011).

Blood vessels in diabetics are particularly susceptible to atherosclerosis. Emissions from production are often much more erratic and considerably more difficult to predict.
