    Molecular epidemiological typing within the European Gonococcal Antimicrobial Resistance Surveillance Programme reveals predominance of a multidrug-resistant clone2013In: Eurosurveillance, ISSN 1025-496X, E-ISSN 1560-7917, Vol. 18, no 3, p. 14-23, article id 20358Article in journal (Refereed)
    Abstract [en]

    Treatment of gonorrhoea is threatened by antimicrobial resistance, and decreased susceptibility and resistance to recommended therapies is emerging in Europe. Current associations between resistance and molecular type remain poorly understood. Gonococcal isolates (n=1,066) collected for the 2009 and 2010 European Gonococcal Antimicrobial Surveillance Programme were typed by Neisseria gonorrhoeae multi-antigen sequence typing (NG-MAST). A total of 406 sequence types (STs) were identified, 125 of which occurred in >= two isolates. Seven major genogroups of closely related STs (varying by <= 1% at just one of the two target loci) were defined. Genogroup 1407 (G1407), observed in 20/21 countries and predominant in 13/21 countries, accounted for 23% of all isolates and was associated with decreased susceptibility to cefixime and resistance to ciprofloxacin and raised minimum inhibitory concentrations for ceftriaxone and azithromycin. Genogroup 225 (G225), associated with ciprofloxacin resistance, was observed in 10% of isolates from 19/21 countries. None of the other genogroups were associated with antimicrobial resistance. The predominance of a multidrug-resistant clone (G1407) in Europe is worrying given the recent reports of recommended third generation cephalosporins failing to treat infections with this clone. Identifying associations between ST and antimicrobial resistance aids the understanding of the dissemination of resistant clones within a population and could facilitate development of targeted intervention strategies.

    Clinical Neisseria gonorrhoeae isolate with a N. meningitidis porA gene and no prolyliminopeptidase activity, Sweden, 2011-danger of false-negative genetic and culture diagnostic results2012In: Eurosurveillance, ISSN 1025-496X, E-ISSN 1560-7917, Vol. 17, no 9, p. 5-7, article id 20102Article in journal (Refereed)
    Abstract [en]

    We describe a Neisseria gonorrhoeae strain, found in Sweden in 2011, that harbours a N. meningitidis porA gene causing false-negative results in PCRs targeting the gonococcal porA pseudogene. Furthermore, the strain had no prolyliminopeptidase (PIP) activity that many commercial biochemical kits for species verification in culture rely on. Enhanced awareness of the spread of such strains and screening for them can be crucial.

    Four treatment failures of pharyngeal gonorrhoea with ceftriaxone (500 mg) or cefotaxime (500 mg), Sweden, 2013 and 20142014In: Eurosurveillance, ISSN 1025-496X, E-ISSN 1560-7917, Vol. 19, no 30, p. 2-5, article id 20862Article in journal (Refereed)
    Abstract [en]

    We describe four cases in Sweden of verified treatment failures of pharyngeal gonorrhoea with ceftriaxone (500 mg; n=3) or cefotaxime (500 mg; n=1) monotherapy. All the ceftriaxone treatment failures were caused by the internationally spreading multidrug-resistant gonococcal NG-MAST genogroup 1407 clone. Increased awareness of treatment failures is crucial particularly when antimicrobial monotherapy is used. Frequent test of cure and appropriate verification/falsification of suspected treatment failures, as well as implementation of recommended dual antimicrobial therapy are imperative.

    Multidrug-resistant Neisseria gonorrhoeae isolate, belonging to the internationally spreading Japanese FC428 clone, with ceftriaxone resistance and intermediate resistance to azithromycin, Ireland, August 20182018In: Eurosurveillance, ISSN 1025-496X, E-ISSN 1560-7917, Vol. 23, no 47, p. 6-9, article id 1800617Article in journal (Refereed)
    Abstract [en]

    We describe a multidrug-resistant Neisseria gonorrhoeae urethritis case with ceftriaxone resistance and azithromycin intermediate resistance in a heterosexual man in Ireland, August 2018. Whole-genome sequencing showed that the isolate IR72 belongs to the internationally spreading multidrug-resistant ceftriaxone-resistant FC428 clade, initially described in Japan in 2015. IR72 was assigned MSLT ST1903, NG-MAST ST17842 and NG-STAR type 1133, including the ceftriaxone resistance-mediating penA-60.001. Global awareness of spreading ceftriaxone-resistant gonococcal strains that threaten recommended dual therapies is essential.

    An international invasive meningococcal disease outbreak due to a novel and rapidly expanding serogroup W strain, Scotland and Sweden, July to August 20152016In: Eurosurveillance, ISSN 1025-496X, E-ISSN 1560-7917, Vol. 21, no 45, p. 15-23, article id 30395Article in journal (Refereed)
    Abstract [en]

    The 23rd World Scout Jamboree in 2015 took place in Japan and included over 33,000 scouts from 162 countries. Within nine days of the meeting ending, six cases of laboratory-confirmed invasive serogroup W meningococcal disease occurred among scouts and their close contacts in Scotland and Sweden. The isolates responsible were identical to one-another by routine typing and, where known (4 isolates), belonged to the ST-11 clonal complex (cc11) which is associated with large outbreaks and high case fatality rates. Recent studies have demonstrated the need for high-resolution genomic typing schemes to assign serogroup W cc11 isolates to several distinct strains circulating globally over the past two decades. Here we used such schemes to confirm that the Jamboree-associated cases constituted a genuine outbreak and that this was due to a novel and rapidly expanding strain descended from the strain that has recently expanded in South America and the United Kingdom. We also identify the genetic differences that define the novel strain including four point mutations and three putative recombination events involving the horizontal exchange of 17, six and two genes, respectively. Noteworthy outcomes of these changes were antigenic shifts and the disruption of a transcriptional regulator.

    Most but not all laboratories can detect the recently emerged Neisseria gonorrhoeae porA mutants - results from the QCMD 2013 N. gonorrhoeae external quality assessment programme2014In: Eurosurveillance, ISSN 1025-496X, E-ISSN 1560-7917, Vol. 19, no 8, p. 2-5, article id 20711Article in journal (Refereed)
    Abstract [en]

    We describe the results of the Quality Control for Molecular Diagnostics 2013 Neisseria gonorrhoeae external quality assessment programme that included an N. gonorrhoeae strain harbouring an N. meningitidis porA gene which causes false-negative results in molecular diagnostic assays targeting the gonococcal porA pseudogene. Enhanced awareness of the international transmission of such gonococcal strains is needed to avoid false-negative results in both in-house and commercial molecular diagnostic assays used in laboratories worldwide, but particularly in Europe.

    In recent years, false-negative test results using PCRs targeting the Neisseria gonorrhoeae porA pseudogene have been reported from Australia, Scotland, Sweden and England [1-4]. Further investigations revealed that the gonococcal strains were not clonal, but all had replaced large segments or their entire N. gonorrhoeae porA pseudogene with an N. meningitidis porA gene.

    This report describes the results of the Quality Control for Molecular Diagnostics (QCMD) 2013 N. gonorrhoeae External Quality Assessment (EQA) programme. It included an N. gonorrhoeae strain containing an N. meningitidis porA gene which gives rise to false-negative results in molecular diagnostic assays targeting the gonococcal porA pseudogene. QCMD (www.qcmd.org) is an independent international organisation which provides a wide range of molecular EQA services in the field of infectious diseases to over 2,000 participants in over 100 countries.

    Multidrug-resistant Neisseria gonorrhoeae failing treatment with ceftriaxone and doxycycline in France, November 20172018In: Eurosurveillance, ISSN 1025-496X, E-ISSN 1560-7917, Vol. 23, no 21, p. 1-3, article id 1800264Article in journal (Refereed)
    Abstract [en]

    We report a multidrug-resistant Neisseria gonorrhoeae urogenital and pharyngeal infection with ceftriaxone resistance and intermediate resistance to azithromycin in a heterosexual woman in her 205 in France. Treatment with ceftriaxone plus doxycycline failed for the pharyngeal localisation. Whole-genome sequencing of isolate F-90 identified MIST1903 , NG-MAST ST343, NG-STAR(233) , and relevant resistance determinants. F-90 showed phenotypic and genotypic similarities to an internationally spreading multidrug-resistant and ceftriaxone-resistant clone detected in Japan and subsequently in Australia, Canada and Denmark.

    Outbreak of Neisseria meningitidis capsular group W among scouts returning from the World Scout Jamboree, Japan, 20152016In: Eurosurveillance, ISSN 1025-496X, E-ISSN 1560-7917, Vol. 21, no 45, p. 8-14, article id 30392Article in journal (Refereed)
    Abstract [en]

    The 23rd World Scout Jamboree was held in Japan from 28 July to 8 August 2015 and was attended by over 33,000 scouts from 162 countries. An outbreak of invasive meningococcal disease capsular group W was investigated among participants, with four confirmed cases identified in Scotland, who were all associated with one particular scout unit, and two confirmed cases in Sweden; molecular testing showed the same strain to be responsible for illness in both countries. The report describes the public health action taken to prevent further cases and the different decisions reached with respect to how wide to extend the offer of chemoprophylaxis in the two countries; in Scotland, chemoprophylaxis was offered to the unit of 40 participants to which the four cases belonged and to other close contacts of cases, while in Sweden chemoprophylaxis was offered to all those returning from the Jamboree. The report also describes the international collaboration and communication required to investigate and manage such multinational outbreaks in a timely manner.

    Surveillance of invasive Neisseria meningitidis with a serogroup Y update, Sweden 2010 to 20122014In: Eurosurveillance, ISSN 1025-496X, E-ISSN 1560-7917, Vol. 19, no 42, p. 25-33, article id UNSP 20940Article in journal (Refereed)
    Abstract [en]

    An increase of invasive meningococcal disease caused by Neisseria meningitidis serogroup Y has been noted in Sweden since 2005, and to a lower extent throughout Europe. The present study describes the epidemiology of invasive N. meningitidis isolates in Sweden in the period between 2010 and 2012, with a focus on serogroup Y. We also aimed to find an optimal molecular typing scheme for both surveillance and outbreak investigations. All invasive N. meningitidis isolates in Sweden during the study period (n=208) were genetically characterised. Serogroup Y predominated with 22/57, 31/61 and 44/90 of all invasive isolates (incidence 0.23, 0.33 and 0.46 per 100,000 population) in 2010, 2011 and 2012 respectively. In each of these years, 15/22, 22/31 and 19/44 of serogroup Y isolates were genetically clonal (Y: P1.5-2,10-1,36-2: F4-1: ST-23(cc23), 'porB allele 3-36, fHbp allele 25 and penA allele 22). Our findings further support those of others that currently recommended FetA typing could be replaced by FHbp. Moreover, in line with a previous study that we conducted, the current results indicate that highly variable multilocus variable-number tandem repeat analysis (HV-MLVA) can be used as a first-hand rapid method for small outbreak investigations.

    Finnish new variant of Chlamydia trachomatis escaping detection in the Aptima Combo 2 assay also present in Orebro County, Sweden, May 20192019In: Eurosurveillance, ISSN 1025-496X, E-ISSN 1560-7917, Vol. 24, no 26, p. 10-14, article id 1900370Article in journal (Refereed)
    Abstract [en]

    We identified the first two cases of the Finnish new variant of Chlamydia trachomatis (F-nvCT) beyond Finland in two clinical urogenital specimens in Orebro County, Sweden. These Aptima Combo 2 assay-negative specimens were Aptima Chlamydia trachomatis (CT) assay positive and had the characteristic C1515T mutation in the 23S rRNA gene. From 22 March to 31 May 2019, 1.3% (2/158) of the CT-positive cases in Orebro County were missed because of the F-nvCT. International awareness, investigations and actions are essential.

    Multiple human-to-human transmission from a severe case of psittacosis, Sweden, January-February 20132014In: Eurosurveillance, ISSN 1025-496X, E-ISSN 1560-7917, Vol. 19, no 42, p. 34-39, article id 20937Article in journal (Refereed)
    Abstract [en]

    Proven transmission of Chlamydia psittaci between humans has been described on only one occasion previously. We describe an outbreak which occurred in Sweden in early 2013, where the epidemiological and serological investigation suggests that one patient, severely ill with psittacosis after exposure to wild bird droppings, transmitted the disease to ten others: Two family members, one hospital roommate and seven hospital caregivers. Three cases also provided respiratory samples that could be analysed by PCR. All the obtained C. psittaci sequences were indistinguishable and clustered within genotype A. The finding has implications for the management of severely ill patients with atypical pneumonia, because these patients may be more contagious than was previously thought. In order to prevent nosocomial person-to-person transmission of C. psittaci, stricter hygiene measures may need to be applied.
