Association between antimicrobial usage in livestock and antimicrobial resistance in Escherichia coli isolates from human urinary tract infections in the Netherlands, 2009-2020.

Background: In the last decade, veterinary antimicrobial usage (AMU) and antimicrobial resistance (AMR) among indicator bacteria in livestock have decreased substantially in the Netherlands. The extent to which this decrease has affected AMR levels among human infections remains unclear.

Objectives: To assess the association between AMU in livestock and AMR in Escherichia coli isolates from human urinary tract infections (UTIs).

Temporal association of antimicrobial use in livestock with antimicrobial resistance in non-typhoid human infections in the Netherlands, 2008-2019.

Background: Antimicrobial use (AMU) in livestock contributes to antimicrobial resistance (AMR) among zoonotic pathogens, such as non-typhoid (NTS). Since 2009, the Netherlands has made substantial efforts to reduce AMU in livestock.

Objectives: To assess the association between AMU in livestock and AMR in NTS human isolates.

Human carriage of ESBL/pAmpC-producing and in relation to the consumption of raw or undercooked vegetables, fruits, and fresh herbs.

We investigated to what extent the consumption of raw or undercooked vegetables, fruits, and fresh herbs influences carriage rates of ESBL/pAmpC-producing and (ESBL-E/K) in the general population. We assessed long-term carriage and changes in ESBL-E/K prevalence over time, by comparing the results to findings in the same population 5 years earlier. Between July and December 2021, participants sent in two fecal samples and questionnaires, 3 months apart.

The use of aminopenicillins in animals within the EU, emergence of resistance in bacteria of animal and human origin and its possible impact on animal and human health.

Aminopenicillins have been widely used for decades for the treatment of various infections in animals and humans in European countries. Following this extensive use, acquired resistance has emerged among human and animal pathogens and commensal bacteria. Aminopenicillins are important first-line treatment options in both humans and animals, but are also among limited therapies for infections with enterococci and Listeria spp.
