Characterisation of Neisseria meningitidis C:2b:P1.2,5 isolates in Poland.
This study aimed to characterise Neisseria meningitidis C:2b:P1.2,5 isolates from Poland, which have now become predominant among serogroup C isolates in this country. Overall, 44 isolates (25 invasive and 19 from contact carriers) were typed by whole-cell ELISA and pulsed-field gel electrophoresis. Additionally, the invasive isolates were analysed by multilocus sequence typing, which revealed that they all belonged to the ST-8 complex/cluster A4. The emergence of this clone in other countries has resulted in mass immunisation campaigns and has been associated with a higher level of decreased susceptibility to penicillin; however the present study detected only one isolate that was penicillin-non-susceptible.
