morePlaque Bacteria: Ecology, Pathogenesis, and Control
The human mouth contains an abundance of micro organisms. These oral bacteria have certain characteristics in common. For example, all possess surface molecules and the concomitant capacity for cell to cell interaction. This contributes to their ability to form dental plaque. Plaque is a protective bacterial film which naturally accumulates on teeth. It has a number of beneficial effects. Excessive plaque formation, however, may also contribute to diseases such as gingivitis and peridontitis. Therefore, bacterial proliferation in the mouth requires some form of control. Various means can be employed to maintain microbial populations at levels compatible with health. Currently, antimicrobial agents are used. Perhaps in the future additional methods will evolve.

moreChild care centers and play areas such as ball pits at fast-food restaurants are both places where young children are at risk for exposure to illness and infectious diseases because of their interaction with many other children, with items used by other young children, and with staff who have interacted with other young children and their playthings. Common illnesses transmitted in such a way include diarrhea and upper respiratory tract infections. This means that special care needs to be taken to prevent the spread of illness and infectious diseases in these places, and simple measures need to be developed to help reduce the incidence of infection. In the case of ball pits, procedures to maintain the hygiene of the area need to be instituted.
In child care centers, the staff are often overworked and don't
