:shifty. I notice the smell of rancid body oils in sheets. I sometimes can smell it in the houses I visit. Sometimes it is severe and very unpleasant. At one friend's house I would have to walk by her bedroom to use the bathroom and the smell really was strong to me.
Yeast is by far the most common type of organism found in a diaper rash. The organism is quite prevalent and thrives on warm, moist skin. Yeast involvement should be suspected in any diaper rash that hasn't improved dramatically with 72 hours of appropriate therapy.
Causes may include: 1  Diaper rash (rash in the diaper area) is a skin irritation caused by long-term dampness and by urine and feces touching the skin.  Yeast diaper rash is caused by a type of yeast called candida, which also causes thrush in the mouth. The rash looks different from a regular diaper rash. It is very red, and there are usually small red bumps on the outer edges of the rash. This rash requires treatment with medicine.
