Table 2.

Competent S. mutans NG8 and mixtures with P. gingivalis or MVs from P. gingivalis were transformed with exogenous chromosomal DNA gtfD and the transformation frequencies are indicated as numbers of tetracycline-resistant colonies/100 μL. Assessments were performed in triplicate in two independent experiments. Data presented are the means ± standard deviation (n=6).

Species Transformation Efficiency (colonies/100 μL)
S.m. NG8 437.5 ± 53.9
S.m. NG8 + P.g. 381 11.6 ± 4.7
S.m. NG8 + P.g. 381 MVs 14.6 ± 3.8
S.m. NG8 comC- 0.3 ± 0.5
