A. actinomycetemcomitans profile and red complex bacterial species of an Afro-Brazilian community: A comparative study

Despite no statistically significant differences related to the red complex species, Afro-Brazilian descendants harboured higher levels of A. actinomycetemcomitans. Also, our findings confirm that Afro-descendant populations are preferably colonised by A. actinomycetemcomitans serotype b as well as JP2 strains.
