Resumo
Several studies report the correlation between the carious prevalence and the
number of mutans streptococci (MS) and other microorganisms in the saliva.
We investigated the distribution of MS and yeasts in the saliva of 93
members of six families with at least 3 generations. Whole non stimulated
saliva was collected, diluted and dropped onto SB20 agar and CHROMagar
Cândida for the isolation of MS and yeasts, respectively. After the
incubation, the colonies presenting typical macroscopic characteristics were
counted and picked up in specific media for biochemical typing. Mutans
streptococci were isoláted from (86.0%) members and the counts ranged from
0.003x105'(log 2.477) to 1600.0xl05 (log 8.204) CFU/mL saliva. Ali 73
adults were colonized by MS, but these bactéria were detected in 7 (35,0%)
of the 20 children. Streptococcus mutans occurred in 78 (97.5%) members,
and 51 (63.7%) were monocolonized. Streptococcus sobrinus occurred in 29
(36.3%) and 2 (2.5%) were monocolonized. Twenty-seven (33.8%) persons
were colonized with S. mutans and S. sobrinus, Moreover. 64 (68.6%)
members were colonized with yeasts. The results showed a high prevalence
(86.0%) of MS and yeasts (68.6%) in the saliva, suggesting the high risk of
interfamilial transmission of these microorganisms.
