Overview

What is he best known for?

The fields of study he is best known for:

  • Gene
  • Bacteria
  • DNA

His main research concerns Microbiology, Virulence, Genetics, Brucella and Brucella suis. His work carried out in the field of Microbiology brings together such families of science as Aroa, Enterobacteriaceae, Escherichia coli and Salmonella. His study in Virulence is interdisciplinary in nature, drawing from both Virology, Sleeping Beauty transposon system, Burkholderia vietnamiensis, Transposon mutagenesis and Innate immune system.

His studies deal with areas such as Pathogen, Intracellular parasite, Phagosome, Phagosome acidification and Effector as well as Brucella. His biological study spans a wide range of topics, including Secretion, Operon and Transposable element, Transposon integration. David O'Callaghan combines subjects such as Sinorhizobium meliloti and Restriction site with his study of Genome.

His most cited work include:

  • The genome sequence of the facultative intracellular pathogen Brucella melitensis (489 citations)
  • A homologue of the Agrobacterium tumefaciens VirB and Bordetella pertussis Ptl type IV secretion systems is essential for intracellular survival of Brucella suis. (392 citations)
  • Brucellosis: a worldwide zoonosis. (317 citations)

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

David O'Callaghan mostly deals with Microbiology, Virulence, Brucella, Brucella suis and Genetics. His research in Microbiology intersects with topics in Virology, Salmonella, Bacteria and Enterobacteriaceae, Escherichia coli. His Virology research incorporates elements of Aroa, Immune system and Antigen.

His Virulence study integrates concerns from other disciplines, such as Pathogen, Caenorhabditis elegans, Mutant, Zebrafish and Innate immune system. His work deals with themes such as Virulence factor, Phylogenetics and Genomics, which intersect with Brucella. The concepts of his Brucella suis study are interwoven with issues in Secretion, Periplasmic space, Operon and Agrobacterium tumefaciens.

He most often published in these fields:

  • Microbiology (65.22%)
  • Virulence (51.30%)
  • Brucella (39.13%)

What were the highlights of his more recent work (between 2012-2021)?

  • Microbiology (65.22%)
  • Brucella (39.13%)
  • Virulence (51.30%)

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

His scientific interests lie mostly in Microbiology, Brucella, Virulence, Brucellosis and Genetics. His Microbiology research is multidisciplinary, incorporating perspectives in Secretion, Bacteria, Staphylococcus aureus and Brucella suis. In the field of Brucella, his study on Brucella melitensis overlaps with subjects such as Matrix assisted laser desorption ionization time of flight, Desorption and Protocol.

David O'Callaghan has researched Virulence in several fields, including Pathogen, Intracellular parasite, Escherichia coli, Phylogenetics and Innate immune system. His Brucellosis research incorporates themes from One Health, Chronic infection, Zoonosis and Disease. His study in the field of Inverted repeat, Plasmid and Genome also crosses realms of Host Factor 1 Protein.

Between 2012 and 2021, his most popular works were:

  • Comparative Phylogenomics and Evolution of the Brucellae Reveal a Path to Virulence (75 citations)
  • Comparative Phylogenomics and Evolution of the Brucellae Reveal a Path to Virulence (75 citations)
  • A Brucella spp. Isolate from a Pac-Man Frog (Ceratophrys ornata) Reveals Characteristics Departing from Classical Brucellae. (38 citations)

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

  • Gene
  • Bacteria
  • DNA

His primary areas of investigation include Brucella, Phylogenetics, Virulence, Intracellular parasite and Innate immune system. The study incorporates disciplines such as Chromatography and Mass spectrometry in addition to Brucella. His Phylogenetics research is multidisciplinary, incorporating elements of Strain, Brucella inopinata, Ochrobactrum anthropi and Microbiology.

His Intracellular parasite research is classified as research in Genetics. His Innate immune system study incorporates themes from Respiratory burst, Burkholderia cepacia complex, Burkholderia cenocepacia and Bacteria. As part of his studies on Pseudomonas aeruginosa, he frequently links adjacent subjects like Immunology.
