Abstract Background Influenza A virus causes annual epidemics in humans and is associated with significant morbidity and mortality. Haemagglutinin (HA) and neuraminidase (NA) gene sequencing have traditionally been used to identify the virus genotype, although their utility in detecting outbreak clusters is still unclear. The objective of this study was to determine the utility, if any, of whole-genome sequencing over HA/NA sequencing for infection prevention and control (IPC) in hospitals. Methods We obtained all clinical samples from influenza (H1N1)-positive patients at the Great Ormond Street Hospital between January and March 2016. Samples were sequenced using targeted enrichment on an Illumina MiSeq sequencer. Maximum likelihood trees were computed for both whole genomes and concatenated HA/NA sequences. Epidemiological data was taken from routine IPC team activity during the period. Results Complete genomes were obtained for 65/80 samples from 38 patients. Conventional IPC analysis recognized 1 outbreak, involving 3 children, and identified another potential cluster in the haemato-oncology ward. Whole-genome and HA/NA phylogeny both accurately identified the previously known outbreak cluster. However, HA/NA sequencing additionally identified unrelated strains as part of this outbreak cluster. A whole-genome analysis identified a further cluster of 2 infections that had been previously missed and refuted suspicions of transmission in the haemato-oncology wards. Conclusions Whole-genome sequencing is better at identifying outbreak clusters in a hospital setting than HA/NA sequencing. Whole-genome sequencing could provide a faster and more reliable method for outbreak monitoring and supplement routine IPC team work to allow the prevention of transmission.

AbstractblaKPC, encoding one of five dominant global carbapenemase families, is increasingly identified in environmental species difficult to characterize using routine diagnostic methods, with epidemiological and clinical implications. During environmental hospital infection prevention and control investigations (Manchester, UK) we used whole genome sequencing to confirm species identification for isolates infrequently associated withblaKPCand/or difficult to classify by MALDI-ToF. Four previously undescribedblaKPC-carrying species were identified from the hospital environment, including a putative, novelEnterobacterspecies.

Third Generation Cephalosporins

Multi-drug-resistant Enterobacteriales are an increasing problem and include those mediated by extended-spectrum β‎-lactamases (ESBLs) and carpapenemase production (CPE). Third-generation cephalosporins are inactivated by ESBLs but for CPEs there are much fewer options for treatment. The challenge in detection, management, and treatment is compounded by CPEs occurring amongst such a broad category of Gram-negative bacilli and because the genetic elements are very mobile, often being quickly and widely disseminated through plasmids. Phenotypic tests for identification have their limitations and there is increasing emphasis on PCR with microarrays and whole genome sequencing being available in specialist centres. Colistin is often the drug of first choice for CPE infections but is usually combined with another agent such as an aminoglycoside. Aggressive infection prevention and control precautions are mandatory given the propensity to spread, the reduced options for treatment, and a lack of insight to patterns and duration of carriage.
