What were the risk factors and trends in antimicrobial resistance for enteric fever in London 2005-2012?

A study was undertaken to determine the risk factors and trends in antimicrobial resistance for enteric fever. Demographic, antimicrobial susceptibility, typing and epidemiological data were examined for 2005-2012 in patients with enteric fever in London. Single and multivariable logistic regression was used to determine the risk factors associated with antibiotic resistance.

An extended genotyping framework for Salmonella enterica serovar Typhi, the cause of human typhoid.

The population of Salmonella enterica serovar Typhi (S. Typhi), the causative agent of typhoid fever, exhibits limited DNA sequence variation, which complicates efforts to rationally discriminate individual isolates. Here we utilize data from whole-genome sequences (WGS) of nearly 2,000 isolates sourced from over 60 countries to generate a robust genotyping scheme that is phylogenetically informative and compatible with a range of assays.

High-Resolution Analysis by Whole-Genome Sequencing of an International Lineage (Sequence Type 111) of Pseudomonas aeruginosa Associated with Metallo-Carbapenemases in the United Kingdom.

Whole-genome sequencing (WGS) was carried out on 87 isolates of sequence type 111 (ST-111) of Pseudomonas aeruginosa collected between 2005 and 2014 from 65 patients and 12 environmental isolates from 24 hospital laboratories across the United Kingdom on an Illumina HiSeq instrument. Most isolates (73) carried VIM-2, but others carried IMP-1 or IMP-13 (5) or NDM-1 (1); one isolate had VIM-2 and IMP-18, and 7 carried no metallo-beta-lactamase (MBL) gene. Single nucleotide polymorphism analysis divided the isolates into distinct clusters; the NDM-1 isolate was an outlier, and the IMP isolates and 6/7 MBL-negative isolates clustered separately from the main set of 73 VIM-2 isolates.

Trends in antibiotic susceptibility of enteric fever isolates in East London.

Background: The study sought evidence for changes in the proportions of antibiotic resistant strains among isolates of Salmonella enterica serovar Typhi (S. typhi) and Salmonella enterica serovar Paratyphi (S. paratyphi) between 2005 and 2012.

Mapping public engagement with research in a UK University.

Notwithstanding that 'public engagement' is conceptualised differently internationally and in different academic disciplines, higher education institutions largely accept the importance of public engagement with research. However, there is limited evidence on how researchers conceptualise engagement, their views on what constitutes engagement and the communities they would (or would not) like to engage with. This paper presents the results of a survey of researchers in the Open University that sought to gather data to fill these gaps.

East London experience with enteric fever 2007-2012.

Purpose: The clinical presentation and epidemiology for patients with enteric fever at two hospitals in East London during 2007-2012 is described with the aim to identify preventive opportunities and to reduce the cost of treatment.

Methods: A retrospective analysis of case notes from patients admitted with enteric fever during 2007 to 2012 with a microbiologically confirmed diagnosis was undertaken. Details on clinical presentation, travel history, demographic data, laboratory parameters, treatment, patient outcome and vaccination status were collected.

Diagnosis of Clostridium difficile infection by toxin detection kits: a systematic review.

Clostridium difficile can be a fatal hospital-acquired infection and its prevalence has increased. Accurate diagnosis of C difficile is essential for patient management, infection control, and for defining its epidemiology. We did a systematic review of commonly used commercial assays for detection of C difficile toxin (CDT) A and B in stool samples.

Epidemiology of invasive pneumococcal disease in Kumasi, Ghana.

There are few data on the epidemiology of invasive pneumococcal disease in Africa. We undertook a prospective study of these infections in Kumasi, Ghana, collecting clinical data on all patients with laboratory-confirmed pneumococcal meningitis, pneumonia or systemic sepsis associated with bacteraemia. A total of 140 cases were identified in the period from January 2002 to April 2005.
