*Streptococcus viridans comprehends a group composed of Streptococcus sanguis group, Streptococcus milleri group, and S. mitis. Species of Streptococus viridans are not determined in this study.
**(%) the percentage of bacteria indicates the percentage of bacteria detected versus the total bacterial population.
***Bacteria constituting less than 5% of the total bacterial population are grouped together as other spp.
