Abstract:
:Gram-negative Aggregatibacter actinomycetemcomitans can be distinguished (based on the promoter structure of the leukotoxin operon) into JP2 and non-JP2 genotypes, with the former found to be more pathogenic than the latter. Here we report the first complete genome sequence of a serotype b non-JP2 strain of A. actinomycetemcomitans.
