This study evaluated two new molecular typing methods, multiple\u2010locus variable number tandem repeat analysis (MLVA) and repetitive sequence\u2010based PCR (rep\u2010PCR) (DiversiLab; bioM\u00e9rieux) and compared them with current recommended methodologies. This retrospective study included 36 invasive <jats:italic>N. meningitidis<\/jats:italic> serogroup C isolates collected in Sweden 2001 through 2009 and previously subjected to outbreak investigation. All strains were typed with highly variable\u2010MLVA (HV\u2010MLVA) and rep\u2010PCR. The isolates were further characterized by multilocus sequence typing (MLST) and sequencing of the <jats:italic>fetA<\/jats:italic>,<jats:italic> fHbp<\/jats:italic>,<jats:italic> penA<\/jats:italic>,<jats:italic> porA<\/jats:italic> and <jats:italic>porB<\/jats:italic> genes. The results showed that HV\u2010MLVA had the highest index of diversity (0.99) and rep\u2010PCR had the highest congruence (40%) with the currently recommended typing methods. The HV\u2010MLVA correlated best to the spatiotemporal connections and had the overall highest Adjusted Wallace coefficients, suggesting that HV\u2010MLVA can predict the results of the other typing methods in the study. We therefore suggest that after initial confirmation of species, serogroup and genosubtype, HV\u2010MLVA should be used as the most discriminatory method for first hand investigation of <jats:italic>N. meningitidis<\/jats:italic> serogroup C isolates.<\/jats:p>","DOI":"10.1111\/apm.12022","type":"journal-article","created":{"date-parts":[[2012,12,11]],"date-time":"2012-12-11T19:01:11Z","timestamp":1355252471000},"page":"503-510","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Evaluation
