Fungal Infections: Types of Mycoses Happen when fungi pass the resistance barriers of the body and establish infection. Characterize mycoses by ________________________________. Superficial Mycoses: Most patients are not even aware that they have condition. Fungi only growing on dead skin, hair and nails. Fungus doesn’t secretes metabolites into body. Cutaneous Mycoses: Fungi growing and secreting metabolites into the skin. Person is definitely aware of the infection. An example of this is Epidermophyton floccosum , one of the causes of athlete's foot. Subcutaneous Mycoses: Fungus must be traumatically implanted into the body. Systemic Mycoses: Fungi are inhaled into the lungs and subsequently are transported to other internal organs, usually through the bloodstream.
