Measure the presence of staphylococci and streptococci in the throat and nose of individuals, as well as, frequently used inanimate objects (formite). In addition, be able to distinguish pathogenic from non pathogenic staphylococci and streptococci.

The ID card is something that is constantly in contact with many things. Students swipe into the dining halls and buildings. In order to swipe into places your hands come into direct contact with the ID card and your hands come into contact with many things as the day progresses.
