Stages of Bacterial Colonization
A. Initial Colonization
1. Within a short time after cleaning, Gram-positive cocci and adhere penetrate acquired film movie (Fig. 6-14a).
2. After 24 hours, plaque biofilm collected from the surface of the teeth consists mainly of streptococci, Streptococcus sanguis the most dominant.
B. Intermediate Coaggregation
1. At this stage, Gram-positive cocci and rods coaggregate and multiply.
2. Gram-positive rods, and to multiply and eventually more than cocci.
C. gram-negative microorganisms
1. Gram-negative bacteria, which have weak capacity to adhere to the tooth, coaggregate with Gram-positive cocci and bacilli.
2. F. nucleatum, Prevotella intermedia, and other anaerobic gram-negative bacteria to adhere in this manner.
D. a wide range of gram-negative microorganisms
1. The number and variety of plaque biofilm growth and include a large number of gram-negative microorganisms.
2. P. gingivalis and Capnocytophaga gingivalis, as well as a large number of other gram-negative microorganisms living in a protective environment biofilms (Fig. 6-14D).
3. Mature plaque biofilm is a very complex combination of several types of bacteria. Pathogenicity-pathogenic potential-bacteria United in biofilms, much more than certain types of pathogens.
