Abstract
The aim of the study presented here was to analyze parapertussis infections occurring in the region of Warsaw, Poland, between 1995 and 2002 and to characterize the Bordetella parapertussis isolates using macrorestriction digestion of genomic DNA. Fourteen of the 17 patients with confirmed Bordetella parapertussis infection were between the ages of 5 and 9 years, and 14 had documented vaccination with the diphtheria-tetanus-pertussis whole-cell vaccine; for the remaining three patients vaccination data was not available. DNA fingerprinting performed using recommended standard methodology revealed a close relationship between the examined strains and reference strain ATCC 9305, thus confirming the conservative nature of Bordetella parapertussis.
