Q:

Is gram-positive cocci contagious?

A:

Gram-positive cocci, such as Staphylococcus and Streptococcus, are contagious. Staphylococcus aureus, for example, is a common cause of hospital-acquired pneumonia, surgical wound infections, endocarditis, osteomyelitis and skin infections. The spread of bacterial infection can be airborne, by directly using infected intravenous catheters and prosthetic implants, or by sexual intercourse.

Most of these bacteria are ubiquitous, so good personal hygiene and frequent hand washing are required to avoid diseases caused by them. Treatment of diseases caused by gram-positive cocci is primarily by administering antibiotics. Further medical treatment, such as debridement, respiratory assistance and administering intravenous fluids, may be necessary depending on the disease.

  • Q:

    How is it possible to determine if a runner over pronates or under pronates?

    A:

    The individual level of pronation, whether under, over or normal, can be determined by measuring the arch of the foot, which can be done by a professional foot expert or podiatrist or, alternatively, a simpler test can be performed at home. To perform the test at home, water is poured into a shallow pan, the foot is dipped evenly into the water and then the foot is pressed against a thick piece of paper or cardboard — it is best for the experimenter to stand naturally on the paper. The shape of the resulting footprint can then be compared to examples of feet that exhibit under-pronation, over-pronation or normal pronation.
