Abstract

Previous observations have revealed that environmental nondermatophyte molds (NDM) can grow inside specific hydrogel pads (LaserAid). Some of these NDM might be responsible for superficial and invasive mycoses as well as for allergic respiratory and cutaneous disorders. The load of NDM propagules in the environment is considered to be an important risk factor for all these diseases. It is postulated that the quantification of the responsible fungi deposited at the skin surface may be an indicator of a recent exposure to environmental fungi. The aim of the present study was to assess using the LaserAid hydrogel pads, the density of living NDM adhering to the skin surface of healthy subjects. Sterile hydrogel pads were applied in a repeat procedure onto the normal-looking skin of the palms and face of 35 healthcare workers who were active in low exposure areas. Similar samplings were performed after washing the skin with a regular skin cleanser, or after applying an alcohol solution or a povidone iodine solution. As controls, 20 sterile pads were exposed for a few minutes to ambient air of the laboratory without any contact with the skin. Each of these samples was stored for 2 weeks at room temperature in a clean protected enviro...Continue Reading
