Detailed explanation-1: -Nail fungus is caused by various fungal organisms (fungi). The most common is a type called dermatophyte. Yeast, bacteria and molds also can cause nail infections. The discoloration from a bacterial infection tends to be green or black.
Detailed explanation-2: -Four types of onychomycosis are recognized based on the site and pattern of fungal invasion. Dermatophyte fungi are the predominant pathogens, but yeasts (especially Candida albicans) and nondermatophyte molds may also be implicated. Accurate diagnosis requires direct microscopy and fungal culture.
Detailed explanation-3: -Onychomycosis does infect viable nail matrix. Onychomycosis secondarily damages the nail matrix as the nail bed becomes hyperkeratotic and thickened in an effort to shed the fungal infection. The dermatophyte also invades the overlying nail plate, detaching and distorting it over time.
