ABSTRACT
Objective:
To investigate a method to identify Actinobacillus actinomycetemcomitans serotypes by polymerase chain reaction.Methods:
18 Actinobacillus actinomycetemcomitans strains representing serotypes a to f were used in the test. 6 pairs of specific oligonucleotide primers for gene clusters involved in the biosynthesis of serotype specific polysaccharide antigens were designed. The primers were developed and evaluated in a genetic method of identifying serotypes of Actinobacillus actinomycetemcomitans strains by using a PCR assay.Results:
Each pair of primers can specifically identify one serotype of Actinobacillus actinomycetemcomitans strains. No cross reaction was observed in all 18 strains. The PCR product sizes were as follows 428 bp (serotype a), 298 bp (serotype b), 559 bp (serotype c), 690 bp (serotype d), 211 bp (serotype e) and 232 bp (serotype f).Conclusion:
PCR method may be useful to identify Actinobacillus actinomycetemcomitans serotypes rapidly and directly.
