title: [Genetic subgroups of Neisseria meningitidis serogroup A isolated from patients with disseminated forms of meningococcal infection in Moscow, 1969-2006].
abstract: Results of microbiological monitoring for serogroup A Neisseria meningitidis circulated in Moscow from 2002 to 2006 are presented. Using multilocus sequence-typing, molecular and epidemiologic characteristics of 32 cultures isolated from cerebro-spinal fluid of patients with generalized forms of meningococcal infection. Typed isolates belonged to 4 sequence types: CT-3349 (detected in 24 cultures), CT-2 (detected in 5 cultures), CT-75 (detected in 2 cultures), and CT-5803 (detected in 1 culture). All sequence types (except CT-5803) were detected in Moscow in previous years. Using Internet database (http://pubmlst.org/neisseria) they were genetically characterized and compared with data on serogroup A meningococci circulated in Moscow before 2002., meningococci belonging to epidemically dangerous genetic subgroup III were not detected between characterized strains. Typed isolates were distributed between subgroups VI and X, which are typical for the area under surveillance. Genetic changes in Moscow population of Neisseria meningitidis serogroup A, which manifested by shift of dominating genetic subgroup after 2002-2003, were analyzed.
