On the skin, even though its more likely to happen from the air if this for your Biology homework.
Broken skin is how the MRSA infection is transmitted.
Anytime the skin is broken there is a risk of infection.
When a fracture breaks the skin, it is a compound fracture or open fracture. Because the skin is broken, there is a possibility of infection.
Infection is always a possibility when the skin is broken, although this rarely occurs
"Although you might not like to think about it, millions of microorganisms, including bacteria, are living on the surface of your skin. Most of the time they are harmless, but, if you get a cut or even an insect bite everyday bacteria may take the opportunity to slip under the skin and cause an infection." source: http://www.healthology.com/skin-problems/skin-problems-information/article1216.htm
The increased availability of nutrients allows microorganisms to replicate. The skin and mucous membranes are body's first line of defense and are mostly impenetrable to microorganisms, unless broken or damaged by tissue injury.
Sounds like a wart, not a fungal infection.
Yes, if it is a comminuted [broken in tiny bits] or compound[bone pushing thru skin] fracture. Both usually involve surgery, and any open wound is prone to infection. Wash hands frequently and follow wound care instructions TO THE LETTER.
Skin is a great barrier to invasion by microbes.
The worst that could happen is that a bad infestation could lead to the skin of the scalp being broken and bleeding then leading to a skin infection.
Many types of microorganisms are normally found on a person's skin. Presence of these microorganisms is noted on a skin culture report as "normal flora."
If the skin isn't broken, not at all. The ice may cause cold-burns, though. If the skin is broken, salt can help to keep the wound clean but may also result in scarring.
