Abstract

Streptococcus strains isolated from different categories- male, female and children of caries active and caries free mouth, where tested to characterize their tolerance efficiency for growth under varying temperature, pH, moisture, salt concentration, sugar concentration, oxidative stress, and percentage of CO₂ availability. These environmental factors are critical and ubiquitous environmental signals that govern the development and virulence of diverse microbial species. Isolated Streptococcus strains from different oral disease condition showed variation in their growth and virulence property under different environmental condition. Isolated Streptococcus strains where inhibited by selected Lactobacilli and Bifidobacterium strains isolated from cow milk, which shows interspecies competitive exclusion.

Keywords
