Identification of Porphyromonas gingivalis genes required for iron/heam acquisition and biofilm formation

Grant number: 300006


Periodontal diseases are some of the most common bacterial diseases of humans and along with dental caries, account for approximately 90% of all tooth loss in the Australian population. A recent survey of oral health in Australia found that in the 30-34 age group over 20% of people had moderate to severe periodontal disease, indicating that periodontitis is a major public health problem. Specific bacteria, especially Porphyromonas gingivalis, that grow as bacterial biofilms (dental plaque) cause periodontal disease. In this study we will utilise the latest technology available to determine which genes of the bacterium are important for biofilm growth, iron acquisition and virulence in an ani..
