Journal ArticleDOI
Extended-spectrum β-lactamase genes of Escherichia coli in chicken meat and humans, The Netherlands.
I. T. M. A. Overdevest,Ina Willemsen,Martine C. Rijnsburger,Andrew Eustace,Li Xu,Peter M. Hawkey,Max Heck,Paul H. M. Savelkoul,Christina M. J. E. Vandenbroucke-Grauls,Kim van der Zwaluw,Xander W. Huijsdens,Jan Kluytmans +11 more
TL;DR: The findings suggest that the abundant presence of ESBL genes in the food chain may have a profound effect on future treatment options for a wide range of infections caused by gram-negative bacteria.
Journal ArticleDOI
Extended-Spectrum β-Lactamase–Producing Escherichia coli From Retail Chicken Meat and Humans: Comparison of Strains, Plasmids, Resistance Genes, and Virulence Factors
Jan Kluytmans,I. T. M. A. Overdevest,Ina Willemsen,Marjolein F. Q. Kluytmans-van den Bergh,Kim van der Zwaluw,Max Heck,Martine C. Rijnsburger,Christina M. J. E. Vandenbroucke-Grauls,Paul H. M. Savelkoul,Brian D. Johnston,David M. Gordon,James R. Johnson +11 more
TL;DR: Significant genetic similarities among ESBL-EC isolates from chicken meat and humans according to mobile resistance elements, virulence genes, and genomic backbone are found and raises serious food safety questions regarding the abundant presence of ES BL-EC in chicken meat.
Journal ArticleDOI
Appropriateness of Antimicrobial Therapy Measured by Repeated Prevalence Surveys
Ina Willemsen,Anneke Groenhuijzen,Diana Bogaers,Arie Stuurman,Peter H. J. van Keulen,Jan Kluytmans +5 more
TL;DR: It is shown that in a setting with a low use of AMT, there are few patients who inadvertently do not receive AMT and on the other hand, a substantial number of the patients are treated inappropriate.
Journal ArticleDOI
Correlation between antibiotic use and resistance in a hospital: temporary and ward-specific observations.
TL;DR: At the level of individual medical specialties within one hospital, a higher prevalence of antimicrobial use among patients was associated with a significantly higher observed antimicrobial resistance.
Journal ArticleDOI
Next-Generation Sequencing for Typing and Detection of Resistance Genes: Performance of a New Commercial Method during an Outbreak of Extended-Spectrum-Beta-Lactamase-Producing Escherichia coli
J. Veenemans,I. T. M. A. Overdevest,Eveline Snelders,Ina Willemsen,Y. Hendriks,A. Adesokan,G. Doran,S. Bruso,A. Rolfe,Annika Pettersson,Jan Kluytmans +10 more
TL;DR: Evaluated the performance of a new NGS assay during an outbreak of sequence type 131 (ST131) Escherichia coli infections in a nursing home in The Netherlands, which showed that all isolates of this outbreak cluster were strongly related.
