Molecular epidemiology of infection in Aboriginal communities

Destructive diseases of the gum tissue are known to be profoundly affected by modifying factors including systemic diseases such as diabetes, socio-economic conditions and the lack of effective control of microbial accumulation at the gum margin. This investigation will examine the hypothesis that a limited number of pathogenic bacterial strains, defined by quantitative molecular probe analysis, persist in or re-infect individuals to maintain a high disease burden in the presence of adverse modifying factors that prevail in isolated, disadvantaged Aboriginal communities.
