[Genetic diversity analysis of isolates belonging to Bordetella pertussis, Bordetella parapertussis and Bordetella bronchiseptica species].

In this study, Amplified Fragment Length Polymorphism (AFLP) method was used to track differences among human and animal isolates of B. pertussis, B. parapertussis and B. bronchiseptica species. One hundred and sixty representative strains of these species orginated from international and Polish bacterial collections were genotyped according to AFLP involving EcoRI/Msel and SpeI/ApaI restriction/ligation/amplification procedures. This study has confirmed high potential AFLP SpeI/ApaI procedure for intra-species differentiation of B. pertussis and B. bronchiseptica strains. Both AFLP EcoRI/MseI and SpeI/ApaI procedures have been found to be useful for species-specific classification in case of B. pertussis strains. In case of B. bronchiseptica or B. parapertussis species-specific classification, SpeI/ApaI procedure has been found more precise than EcoRI/MseI one.
