: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.
Antibiotic use can lead to increased growth of Candida species. Thus, the fact that the use of commonly prescribed antibiotics such as amoxicillin increases the risk for developing diaper rash is not surprising. Amoxicillin use in infants decreases the number of bacteria and increases the number of C. albicans.
