Escherichia coli ST131, an Intriguing Clonal Group
TL;DR: Six years after the first description of E. coli ST131, this review outlines the principal traits of ST131 clonal group isolates, based on the growing body of published data, and highlights what is currently known and what the authors need to find out to provide public health authorities with better information to help combat ST131.
Journal ArticleDOI
Antibiotic resistance in Enterobacteriaceae: mechanisms and clinical implications.
TL;DR: The underlying principles and clinical implications of the mobility and fixation of resistance genes and the exploitable opportunities and potential threats arising from apparent limitations on diversity in these mobile gene pools are discussed.
Journal ArticleDOI
Chromosomally encoded ESBL genes in Escherichia coli of ST38 from Mongolian wild birds.
Sebastian Guenther,Torsten Semmler,Annegret Stubbe,Michael Stubbe,Lothar H. Wieler,Katharina Schaufler +5 more
TL;DR: The chromosomal integration of bla CTX-M genes in E. coli isolates of ST38 appears to be common and is likely independent of antimicrobial selective pressure in clinical environments, which corroborate the zoonotic potential of environmental isolate of ESBL-producing E.coli, which harbour stably integrated, chromosomally encoded resistance factors.

CTX-M-15-Producing E. coli Isolates from Food Products in Germany Are Mainly Associated with an IncF-Type Plasmid and Belong to Two Predominant Clonal E. coli Lineages.
Alexandra Irrgang,Linda Falgenhauer,Jennie Fischer,Hiren Ghosh,Elisabet Guiral,Elisabet Guiral,Beatriz Guerra,Beatriz Guerra,Silvia Schmoger,Can Imirzalioglu,Trinad Chakraborty,Jens A. Hammerl,Annemarie Käsbohrer,Annemarie Käsbohrer +13 more
TL;DR: Transmission of CTX-M-15-harboring isolates from food-producing animals to food appears probable, as isolates obtained from livestock and food samples within the same time period exhibit comparable characteristics as compared to isolates detected from human.

Basic Local Alignment Search Tool
TL;DR: A new approach to rapid sequence comparison, basic local alignment search tool (BLAST), directly approximates alignments that optimize a measure of local similarity, the maximal segment pair (MSP) score.
Journal ArticleDOI
Rapid and simple determination of the Escherichia coli phylogenetic group.
TL;DR: In this paper, a simple and rapid phylogenetic grouping technique based on triplex PCR was proposed, which uses a combination of two genes (chuA and yjaA) and an anonymous DNA fragment, was tested with 230 strains and showed excellent correlation with reference methods.

Sex and virulence in Escherichia coli: an evolutionary perspective
Thierry Wirth,Daniel Falush,Ruiting Lan,Frances M. Colles,Patience Mensa,Lothar H. Wieler,Helge Karch,Peter R. Reeves,Martin C. J. Maiden,Howard Ochman,Mark Achtman +10 more
TL;DR: The evolution of virulence is linked to bacterial sex because rates of evolution have accelerated in pathogenic lineages, culminating in highly virulent organisms whose genomic contents are altered frequently by increased rates of homologous recombination.

Standardization of pulsed-field gel electrophoresis protocols for the subtyping of Escherichia coli O157:H7, Salmonella, and Shigella for PulseNet.
Efrain M. Ribot,M.A. Fair,R. Gautom,Daniel N. Cameron,Susan B. Hunter,B. Swaminathan,Timothy J. Barrett +6 more
TL;DR: Standardized rapid pulsed-field gel electrophoresis (PFGE) protocols for the subtyping of Escherichia coli O157:H7, Salmonella serotypes, and Shigella species are described.
Journal ArticleDOI
CTX-M enzymes: origin and diffusion
TL;DR: The incorporation of different chromosomal blaCTX-M related genes from different species of Kluyvera has derived in different CTX-m clusters is considered a paradigm in the evolution of a resistance mechanism as discussed by the authors.
