Why is athlete’s foot just on the feet?  Why do they just live there?”

We answered this question on the show...



Chris -  Microbes have their own niche.  There are certain places on the body where they like to be- they're optimised to grow in those places. Feet are wonderful.  They have dead skin which serves as protein, lots of sweat, and it’s warm, and it’s protected, and it’s easy to spread around because you have to put your feet on the ground when you walk about.

It isn't.
The same fungus is happy to live elsewhere on the body if it gets a chance.
It prefers damp conditions and feet are often a very suitable place for it.

One can get yeast/fungal infections in other parts of the body, but it is a different species of yeast, such as Candidiasis sometimes found under breasts, or Tinea corporis found around various parts of the body.

Athlete's foot, or Tinea pedis may in fact be exclusively found on feet (in "normal" individuals).  There may be certain immune deficiency states that could cause it to infect other parts of the body.

Many organisms have very specific targets, as well as specific hosts.  Athlete's foot, or Tinea pedis seems to like the moist, protected area between toes and is transmitted in shower floors.

Certainly feet, shoes, and socks can get a very specific odor.  Perhaps there are other aspects specific to the feet too.

I'm pretty sure it is the same species of trichophyton fungus that causes both athletes foot and jock itch and similar superficial skin fungal infections like that. Candida yeast prefer moister mucus membranes like the throat, vagina, or diaper rash in babies.

The extremely handsome Geezer feet were prone to emanate some fairly remarkable odors. However, I discovered that by wearing the thick and comfy socks that are made with a very high cotton content, the pong is virtually eliminated.

Presumably this is because the cotton tends to wick away the moisture, thereby keeping the tootsies nice and dry.

Interesting,
I see a couple of notes indicating that Athletes foot can spread from the toes to the groin, although I still wonder if the two are commonly separate infections.

[Jock Itch] is often caused by the same type of fungus that causes athlete's foot and, sometimes, ringworm of the scalp. In fact, the fungus that infects your groin area may be spread there from your own athlete's foot infection.

If you have fungal infection, such as athlete's foot, the same organism may cause a rash in your groin.

Are you suggesting I've got Athlete's Nose?



Noses run in our family.
