Przeprowadzono restrykcyjną analizę genomowego DNA szczepów B. pertussis wyizolowanych pod koniec lat sześćdziesiątych i w latach dziewięćdziesiątych oraz szczepów B. pertussis stosowanych do produkcji krajowej szczepionki przeciwkrztuścowej. Oceniono genetyczne pokrewieństwo badanych szczepów. Różnice w profilach DNA szczepów szczepionkowych i szczepów B. pertussis pochodzących z lat 1995-98 w wielu przypadkach wskazywały jedynie na możliwość pokrewieństwa, natomiast w innych na całkowity brak pokrewieństwa między tymi szczepami.
The genotypic and serotypic analysis of B. pertussis strains isolated from the nasopharynx of children with whooping cough in the years 1968 and 1995-98 and B. pertussis vaccine strains was the aim of this study. The genotyping of the examined strains was done by electrophoretic division of DNA in pulsed field. The 3 types (A, B, C) and 2 subtypes (A1 and A2) of DNA restriction patterns were determined for the B. pertussis strains isolated in 1968. The 2 types (D and E) and 10 subtypes (D1- D10) of DNA restriction patterns were identified for B. pertussis strains from the years 1995-98. The DNA restriction patterns of B. pertussis strains isolated in the years 1968 and 1995-98 were not identical what was the evidence of the fact that in the sixties and nineties whooping cough was caused by different B. pertussis clones. The different DNA profiles were also observed for vaccine strains as well as for vaccine strains and current isolates. Differences in DNA patterns of vaccine strains and B. pertussis strains isolated in the years 1995-98 indicated a relationship possibility in some cases while lack of relationship between these strains in other cases. Serotyping of the examined B. pertussis strains was performed by the agglutination method with the sera against B. pertussis agglutinogens 1, 2 and 3. Most strains - 15 (75%) isolated in 1968 possessed only agglutinogens 1 and 3. Serotype 1,2,3 was most frequently observed among isolates from the years 1995-98. This study indicates the expediency of periodical change of B. pertussis vaccine strains in the aspect of whooping cough resurgence in the years 1994-95 and 1997- 98.
