BacteriologyEvaluation of Calcium-Enhanced Media for Colistin Susceptibility Testing by Gradient Agar Diffusion and Broth Microdilution...Despite the increasing reliance on polymyxin antibiotics (polymyxin B and colistin) for treatment of multidrug-resistant Gram-negative infections, many clinical laboratories are unable to perform susceptibility testing due to the lack of accurate and reliable methods. Although gradient agar diffusion is commonly performed for other antimicrobials, its use for polymyxins is discouraged due to poor performance characteristics.
EpidemiologyGenomics for Molecular Epidemiology and Detecting Transmission of Carbapenemase-Producing Enterobacterales in Victoria, Australia, 2012 to 2016Carbapenemase-producing Enterobacterales (CPE) are being increasingly reported in Australia, and integrated clinical and genomic surveillance is critical to effectively manage this threat. We sought to systematically characterize CPE in Victoria, Australia, from 2012 to 2016.
EpidemiologySummary and Trends of the Russian Gonococcal Antimicrobial Surveillance Programme, 2005 to 2016The Russian Gonococcal Antimicrobial Surveillance Programme (RU-GASP) was established in 2004 and operated continuously during the years from 2005 to 2016. The aims of this study were to summarize the RU-GASP results over this 12-year period and evaluate the trends in Neisseria gonorrhoeae antimicrobial resistance in Russia.
EpidemiologyRapid Emergence, Subsidence, and Molecular Detection of Escherichia coli Sequence Type 1193-fimH64, a New Disseminated Multidrug-Resistant Commensal and Extraintestinal PathogenEscherichia coli sequence type 1193 (ST1193) is an emerging multidrug-resistant pathogen. We performed longitudinal and cross-sectional surveillance for ST1193 among clinical and fecal E. coli isolates from Minneapolis Veterans Affairs Medical Center (VAMC) patients and their household members,...
BacteriologyLevels of Mycoplasma genitalium Antimicrobial Resistance Differ by Both Region and Gender in the State of Queensland, Australia: Implications for Treatment GuidelinesMycoplasma genitalium is frequently associated with urogenital and rectal infections, with the number of cases of macrolide-resistant and quinolone-resistant M. genitalium infection continuing to increase. In this study, we examined the levels of resistance to these two common antibiotic treatments...
BacteriologyEvaluation of the CosmosID Bioinformatics Platform for Prosthetic Joint-Associated Sonicate Fluid Shotgun Metagenomic Data AnalysisWe previously demonstrated that shotgun metagenomic sequencing can detect bacteria in sonicate fluid, providing a diagnosis of prosthetic joint infection (PJI). A limitation of the approach that we used is that data analysis was time-consuming and specialized bioinformatics expertise was required, both of which are barriers to routine clinical use.
EpidemiologyEpidemiology and Outcomes of Nontyphoidal Salmonella Bacteremias from England, 2004 to 2015Nontyphoidal Salmonella (NTS) bacteremia causes hospitalization and high morbidity and mortality. We linked Gastrointestinal Bacteria Reference Unit (GBRU) data to the Hospital Episode Statistics (HES) data set to study the trends and outcomes of NTS bacteremias in England between 2004 and 2015.
- Mycobacteriology and Aerobic ActinomycetesDirect Whole-Genome Sequencing of Sputum Accurately Identifies Drug-Resistant Mycobacterium tuberculosis Faster than MGIT Culture Sequencing
The current methods available to diagnose antimicrobial-resistant Mycobacterium tuberculosis infections require a positive culture or only test a limited number of resistance-associated mutations. A rapid accurate identification of antimicrobial resistance enables the prompt initiation of effective treatment.
