Europe-wide expansion and eradication of multidrug-resistant Neisseria gonorrho...
Sánchez-Busó, Leonor; Cole, Michelle J.; Spiteri, Gianfranco; Day, Michaela; Jacobsson, Susanne; Golparian, Daniel; Sajedi, Noshin; Yeats, Corin A.Background: Genomic surveillance using quality-assured whole-genome sequencing (WGS) together with epidemiological and antimicrobial resistance (AMR) data is essential to characterise the circulating Neisseria gonorrhoeae lineages and their association to patient groups (defined by demographic and epidemiological factors). In 2013, the European gonococcal population was characterised genomically for the first t...
Genetic Meningococcal Antigen Typing System (gMATS): A genotyping tool that pre...
Muzzi, Alessandro; Brozzi, Alessandro; Serino, Laura; Bodini, Margherita; Abad, Raquel; Caugant, Dominique; Comanducci, Maurizio; Lemos, Ana PaulaBackground: The Meningococcal Antigen Typing System (MATS) was developed to identify meningococcus group B strains with a high likelihood of being covered by the 4CMenB vaccine, but is limited by the requirement for viable isolates from culture-confirmed cases. We examined if antigen genotyping could complement MATS in predicting strain coverage by the 4CMenB vaccine. Methods: From a panel of 3912 MATS-typed in...
Ten years of external quality assessment (EQA) of Neisseria gonorrhoeae antimic...
Cole, Michelle J.; Quaye, Nerteley; Jacobsson, Susanne; Day, Michaela; Fagan, Elizabeth; Ison, Catherine; Pitt, Rachel; Seaton, Shila; Woodford, NeilBackground: Confidence in any diagnostic and antimicrobial susceptibility testing data is provided by appropriate and regular quality assurance (QA) procedures. In Europe, the European Gonococcal Antimicrobial Susceptibility Programme (Euro-GASP) has been monitoring the antimicrobial susceptibility in Neisseria gonorrhoeae since 2004. Euro-GASP includes an external quality assessment (EQA) scheme as an essentia...
Increase of invasive meningococcal serogroup W disease in Europe, 2013 to 2017
Krone, Manuel; Gray, Steve; Abad, Raquel; Skoczyńska, Anna; Stefanelli, Paola; van der Ende, Arie; Tzanakaki, Georgina; Mölling, PaulaBackground: The total incidence of invasive meningococcal disease (IMD) in Europe has been declining in recent years; however, a rising incidence due to serogroup W (MenW), predominantly sequence type 11 (ST-11), clonal complex 11 (cc11), was reported in some European countries. Aim: The aim of this study was to compile the most recent laboratory surveillance data on MenW IMD from several European countries to ...
Public health surveillance of multidrug-resistant clones of Neisseria gonorrhoe...
Harris, Simon R.; Cole, Michelle J.; Spiteri, Gianfranco; Sánchez-Busó, Leonor; Golparian, Daniel; Jacobsson, Susanne; Goater, Richard; Abudahab, KhalilBackground: Traditional methods for molecular epidemiology of Neisseria gonorrhoeae are suboptimal. Whole-genome sequencing (WGS) offers ideal resolution to describe population dynamics and to predict and infer transmission of antimicrobial resistance, and can enhance infection control through linkage with epidemiological data. We used WGS, in conjunction with linked epidemiological and phenotypic data, to desc...
WGS analysis and molecular resistance mechanisms of azithromycin-resistant (MIC...
Jacobsson, Susanne; Golparian, Daniel; Cole, Michelle; Spiteri, Gianfranco; Martin, Irene; Bergheim, Thea; Borrego, Maria José; Crowley, BrendanOBJECTIVES: To elucidate the genome-based epidemiology and phylogenomics of azithromycin-resistant (MIC >2 mg/L) Neisseria gonorrhoeae strains collected in 2009-14 in Europe and clarify the azithromycin resistance mechanisms. METHODS: Seventy-five azithromycin-resistant (MIC 4 to >256 mg/L) N. gonorrhoeae isolates collected in 17 European countries during 2009-14 were examined using antimicrobial susceptibility...
