% of total viable counts.

G and A are nucleotides within the hemoglobin-binding gene (hbpA-2) at position 525285 of the genome (HK1651) [18].

Mediterranean (M) or West African (W) origin of the JP2 genotype carriers

The proportion of A. actinomycetemcomitans could not be calculated due to contamination of the sample [20].

This isolate of A. actinomycetemcomitans has a 640 bp deletion within the leukotoxin promoter region [21].
