Journal ArticleDOI
Extended-spectrum β-lactamase-producing and AmpC-producing Escherichia coli from livestock and companion animals, and their putative impact on public health: a global perspective
TL;DR: The opinion that animal ESBL-producing E. coli is a major source of human infections is oversimplified, and neglects a highly complex scenario.
Journal ArticleDOI
Virulence genotype of Pasteurella multocida strains isolated from different hosts with various disease status.
Christa Ewers,Antina Lübke-Becker,Astrid Bethe,Sabine Kiebling,Matthias Filter,Lothar H. Wieler +5 more
TL;DR: To learn more about the molecular biology of Pasteurella multocida 289 strains isolated from various clinically healthy and diseased hosts were examined for capsule biosynthesis genes and 14 virulence associated genes by PCR and DNA-DNA-hybridization.
Journal ArticleDOI
The broader context of antibiotic resistance: Zinc feed supplementation of piglets increases the proportion of multi-resistant Escherichia coli in vivo
Carmen Bednorz,Kathrin Oelgeschläger,Bianca Kinnemann,Susanne Hartmann,Konrad Neumann,Robert Pieper,Astrid Bethe,Torsten Semmler,Karsten Tedin,Peter Schierack,Lothar H. Wieler,Sebastian Guenther +11 more
TL;DR: Characterization of subclones of E. coli clones in animals supplemented with zinc suggests an increase in antimicrobial resistance due to influences on plasmid uptake by zinc supplementation, questioning the reasonability of zinc feed additives as a result of the ban of antimicrobial growth promoters.
Journal ArticleDOI
Emergence of OXA-48 carbapenemase-producing Escherichia coli and Klebsiella pneumoniae in dogs
Inka Stolle,Ellen Prenger-Berninghoff,Ivonne Stamm,Sandra Scheufen,Esther Hassdenteufel,Sebastian Guenther,Astrid Bethe,Yvonne Pfeifer,Christa Ewers +8 more
TL;DR: This is the first known report of OXA-48-producing bacteria from companion animals and suggests a nosocomial dissemination rather than repeated introduction by individual patients into the clinic.
Journal ArticleDOI
CTX-M-15-D-ST648 Escherichia coli from companion animals and horses: another pandemic clone combining multiresistance and extraintestinal virulence?
Christa Ewers,Astrid Bethe,Ivonne Stamm,Mirjam Grobbel,Peter A. Kopp,Beatriz Guerra,Michael Stubbe,Yohei Doi,Zhiyong Zong,Axel Kola,Katharina Schaufler,Torsten Semmler,Angelika Fruth,Lothar H. Wieler,Sebastian Guenther +14 more
TL;DR: It is demonstrated that certain subgroups of E. coli D-ST648-CTX-M may represent a novel genotype that combines multiresistance, extraintestinal virulence and zoonotic potential.
