But new research from Columbia University biology professor Lars Dietrich's lab shows that bacteria that form biofilms actually have a highly structured arrangement within those slimy matrices.

They also discovered that this arrangement is upset by mutations that alter the bacterial cell surface. They found that the distribution of sugar influenced by the biofilm's anatomy occurred when ...

The cell wall of most bacteria has an overall net negative charge and thus can be stained directly with a single basic (positively charged) stain or dye. This type of stain allows us to observe the ...

Researchers from the University of Pennsylvania found that the bacteria responsible for tooth decay "shields" itself under blankets of sugars and other bacteria in a crown-like arrangement ...
