What does athletes foot feed on?
the skin and flesh inside the foot
Penicillin has no effect on the fungus that causes athletes foot. Penicillin itself is derived from a fungus. Penicillin is anti-bacterial, it affects bacteria. Penicillin may be used if the athletes foot is serious enough to cause a bacterial infection. Anti-bacterials can cause athletes foot and other fungal infections to worsen by killing the "good" bacteria we all have on our skin and in our bodies. Some of those bacteria feed on fungi.
Athletes foot is a form of a fungal infection. it thrives in moist areas, such as your toes and feet. the easiest way to get athletes foot is to wear damp socks for an extended period of time. it is common with athletes (hence the name) because they run, swim, excessive, and whatever, and their socks get damp and it helps athletes foot to thrive, especially if worn for extended periods.
