The Best AR-15 Triggers on the Market. It was one of those hot summer days in Maine where you fought the humidity more than the heat itself. Lying wrapped in two sweatshirts and a heavy shooting jacket, I appeared to be a heat casualty in the making. Sweat was pouring off me, but I didnât care.
Fungal Nail Infections-Cause. Fungal nail infections can be caused by three different types of fungus, alone or in combination. 1  Dermatophytes are a type of fungus that can grow on the skin, hair, and nails. 2  They don't invade the deeper tissues of the body. 3  The most common dermatophyte, Trichophyton rubrum, causes most cases of athlete's foot.
The primary fungi that cause onychomycosis are Trichophyton rubrum and Trichophyton mentagrophytes. They are dermatophytes (fungi that infect hair, skin, and nails) and feed on keratinized (nail) tissue. The infections they cause are normally confined to the nails, but occasionally spread to the surrounding skin. Another type of onychomycosis is caused by yeast (Candida albicans or Candida parapsilosis).
