- Neisseria meningitidis serogroups B and C have beenresponsible for the majority of invasive meningococcaldisease in Europe. Recently, an increase of N. meningitidisdisease due to serogroup Y has been notedin Sweden (in 2010, the proportion was 39%, with anincidence of 0.23 per 100,000 population), as well as inother northern European countries. We aimed to investigatethe clonal pattern of the emerging serogroup Yin Sweden during 2000 to 2010. The serogroup Y isolatesidentified during this time (n=85) were characterisedby multilocus sequence typing and sequencing ofthe fetA, fHbp, penA, porA and porB genes. The mostfrequent clone (comprising 28 isolates) with identicalallele combinations of the investigated genes, waspartly responsible for the observed increased numberof N. meningitidis serogroup Y isolates. It was sulfadiazineresistant, with genosubtype P1.5-2,10-1,36-2,sequence type 23, clonal complex 23, porB allele 3-36,fetA allele F4-1, fHbp allele 25 and penA allele 22. Thefirst case with disease due to this clone was identifiedin 2002: there was a further case in 2004, six during2006 to 2007, eight during 2008 to 2009, with a peakof 12 cases in 2010. An unusual increase of invasivedisease in young adults (aged 20–29 years) caused bythis clone was shown, but no increase in mortality ratewas observed.
