Table 3. AP PCR types with serotype b isolates (n = 51) divided into leukotoxicity categories based on results of the cell lysis (LDH) method.

	AP PCR types
Genotypes of A.a*	JP2/JP2-like, n (%)	Other, n (%)
JP2	10 (100)	0 (0)
non-JP2 high leukotoxicity	10 (67)	5 (33)
non-JP2 average leukotoxicity	2 (18)	9 (82)
non-JP2 minimal leukotoxicity	2 (13)	13 (87)

*A.a; A. actinomycetemcomitans.

(%): proportion of isolates within each leukotoxicity group.
