2010-01-21ZeitschriftenartikelA novel IS26 structure is surrounding blaCTX-M genes in different plasmids of German clinical isolates of Escherichia coli This report focuses on the molecular characterization of 22 extended-spectrum beta-lactamase (ESBL) producing E. coli isolates collected in a German university hospital, during a period of nine months in 2006. Relationship ...

2008-09-11ZeitschriftenartikelCharacterization of attaching and effacing Escherichia coli (AEEC) isolated from pigs and sheep Background: Attaching and effacing Escherichia coli (AEEC) are characterized by their ability to cause attaching-and-effacing (A/E) lesions in the gut mucosa of human and animal hosts leading to diarrhoea. The genetic ...

2012-01-30ZeitschriftenartikelEmergence of OXA-48-type carbapenemase-producing Enterobacteriaceae in German hospitals Nine carbapenem-resistant Enterobacteriaceae isolates collected from eight patients in five German hospitals were investigated. Six isolates produced the OXA-48 carbapenemase, and three isolates produced OXA-162, which is ...
-
2012-11-26ZeitschriftenartikelFrequent Combination of Antimicrobial Multiresistance and Extraintestinal Pathogenicity in Escherichia coli Isolates from Urban Rats (Rattus norvegicus) in Berlin, Germany Urban rats present a global public health concern as they are considered a reservoir and vector of zoonotic pathogens, including Escherichia coli. In view of the increasing emergence of antimicrobial resistant E. coli ...

2005-01-24ZeitschriftenartikelGenetical and functional investigation of fliC genes encoding flagellar serotype H4 in wildtype strains of Escherichia coli and in a laboratory E. coli K-12 strain expressing flagellar antigen type H48 Background: Serotyping of O-(lipopolysaccharide) and H-(flagellar) antigens is a wideley used method for identification of pathogenic strains and clones of Escherichia coli. At present, 176 O- and 53 H-antigens are ...

2014-12-04ZeitschriftenartikelLow Rates of Antimicrobial-Resistant Enterobacteriaceae in Wildlife in Taï National Park, Côte d’Ivoire, Surrounded by Villages with High Prevalence of Multiresistant ESBL-Producing Escherichia coli in People and Domestic Animals Antimicrobial resistance genes can be found in all ecosystems, including those where antibiotic selective pressure has never been exerted. We investigated resistance genes in a collection of faecal samples of wildlife ...
-
2012-08-31ZeitschriftenartikelMetagenomic abundance estimation and diagnostic testing on species level One goal of sequencing-based metagenomic community analysis is the quantitative taxonomic assessment of microbial community compositions. In particular, relative quantification of taxons is of high relevance for metagenomic ...

2011-06-21ZeitschriftenartikelMolecular characterization of blaNDM-1 in an Acinetobacter baumannii strain isolated in Germany in 2007 Objectives: To investigate the genetic environment of the metallo-β-lactamase gene blaNDM-1 in an Acinetobacter baumannii isolated in 2007 in a German hospital. Methods: Antimicrobial susceptibility testing was performed ...
-
2009-09-01ZeitschriftenartikelPhylogeny and Disease Association of Shiga toxin-Producing Escherichia coli O91 The diversity and relatedness of 100 Shiga toxin–producing Escherichia coli O91 isolates from different patients were examined by multilocus sequence typing. We identified 10 specific sequence types (ST) and 4 distinct ...
-
2010-09-29ZeitschriftenartikelPpiD is a player in the network of periplasmic chaperones in Escherichia coli Background: The inner membrane-anchored periplasmic folding factor PpiD is described as a parvulin-like peptidyl prolyl isomerase (PPIase) that assists in the maturation of the major beta-barrel outer membrane proteins ...
-
2013-02-04ZeitschriftenartikelRecombinant production of Yersinia enterocolitica pyruvate kinase isoenzymes PykA and PykF The glycolytic enzyme pyruvate kinase (PK) generates ATP from ADP through substrate-level phosphorylation powered by the conversion of phosphoenolpyruvate to pyruvate. In contrast to other bacteria, Enterobacteriaceae, ...

-
2015-07-30ZeitschriftenartikelSuRankCo: supervised ranking of contigs in de novo assemblies Background: Evaluating the quality and reliability of a de novo assembly and of single contigs in particular is challenging since commonly a ground truth is not readily available and numerous factors may influence ...
-
2014-04-21ZeitschriftenartikelTwo Novel EHEC/EAEC Hybrid Strains Isolated from Human Infections The so far highest number of life-threatening hemolytic uremic syndrome was associated with a food-borne outbreak in 2011 in Germany which was caused by an enterohemorrhagic Escherichia coli (EHEC) of the rare serotype ...
-
2005-06-20ZeitschriftenartikelViral promoters can initiate expression of toxin genes introduced into Escherichia coli Background: The expression of recombinant proteins in eukaryotic cells requires the fusion of the coding region to a promoter functional in the eukaryotic cell line. Viral promoters are very often used for this purpose. ...
