Overview

What is he best known for?

The fields of study he is best known for:

  • Gene
  • Bacteria
  • DNA

Helge Karch mostly deals with Microbiology, Escherichia coli, Enterobacteriaceae, Virulence and Shiga toxin. The various areas that he examines in his Microbiology study include Plasmid, Shiga-like toxin, Genotype and Virology. The concepts of his Escherichia coli study are interwoven with issues in Toxin, Molecular biology and Polymerase chain reaction.

His Enterobacteriaceae research is multidisciplinary, relying on both Hybridization probe, Feces and Bacteria. His biological study spans a wide range of topics, including Pathogen, Sorbitol and Multilocus sequence typing. His research investigates the link between Shiga toxin and topics such as Intimin that cross with problems in Locus of enterocyte effacement.

His most cited work include:

  • Sex and virulence in Escherichia coli: an evolutionary perspective (1389 citations)
  • Molecular analysis of the plasmid-encoded hemolysin of Escherichia coli O157:H7 strain EDL 933. (650 citations)
  • Escherichia coli Harboring Shiga Toxin 2 Gene Variants: Frequency and Association with Clinical Symptoms (638 citations)

What are the main themes of his work throughout his whole career to date?

Microbiology, Escherichia coli, Shiga toxin, Virulence and Virology are his primary areas of study. His study explores the link between Microbiology and topics such as Genotype that cross with problems in Typing. His Escherichia coli research incorporates themes from Plasmid and Polymerase chain reaction.

His Shiga toxin research includes themes of Molecular biology, Outbreak, Virulence factor and Glycosphingolipid. The Virology study combines topics in areas such as Antibody, Antigen and Intimin. His work carried out in the field of Enterobacteriaceae brings together such families of science as Toxin and Feces.

He most often published in these fields:

  • Microbiology (62.00%)
  • Escherichia coli (54.25%)
  • Shiga toxin (30.00%)

What were the highlights of his more recent work (between 2011-2021)?

  • Shiga toxin (30.00%)
  • Microbiology (62.00%)
  • Escherichia coli (54.25%)

In recent papers he was focusing on the following fields of study:

His primary scientific interests are in Shiga toxin, Microbiology, Escherichia coli, Virulence and Molecular biology. His Shiga toxin research includes elements of Virulence factor, Cytotoxic T cell, Cell culture and Glycosphingolipid. His Microbiology research integrates issues from Escherichia coli O104:H4, Bacterial outer membrane, STX2, Multilocus sequence typing and Enteropathogenic Escherichia coli.

His studies in Multilocus sequence typing integrate themes in fields like Pathogen and Locus of enterocyte effacement. His studies deal with areas such as Plasmid, Diarrhea, Genotype and Virology as well as Escherichia coli. His Virulence study combines topics in areas such as Secretion, Flagellin and Pulsed-field gel electrophoresis.

Between 2011 and 2021, his most popular works were:

  • Multicenter Evaluation of a Sequence-Based Protocol for Subtyping Shiga Toxins and Standardizing Stx Nomenclature (497 citations)
  • The enemy within us: lessons from the 2011 European Escherichia coli O104:H4 outbreak (170 citations)
  • Enterohemorrhagic Escherichia coli hemolysin employs outer membrane vesicles to target mitochondria and cause endothelial and epithelial apoptosis (105 citations)

In his most recent research, the most cited papers focused on:

  • Gene
  • Bacteria
  • DNA

His primary areas of study are Microbiology, Shiga toxin, Escherichia coli, Virulence and Virology. His study of Drug resistance is a part of Microbiology. Helge Karch has researched Shiga toxin in several fields, including Virulence factor, Toxin, Glycosphingolipid, Receptor and Molecular biology.

Helge Karch has included themes like Serotype and Proteinuria in his Escherichia coli study. His research integrates issues of Secretion and Genotype, Multilocus sequence typing, Pulsed-field gel electrophoresis in his study of Virulence. His Virology research is multidisciplinary, incorporating perspectives in Plasmid and Pathogen.
