Our bodies host a variety of microorganisms, some of which are beneficial to us. These microorganisms also include bacteria and fungi. Fungal infections are caused by microscopic plants that live on our skin and on the dead tissue of our hair and nails. The following list contains the more common nail irregularities, diseases and disorders.
Bacteria, fungi, and some viruses can cause paronychia infections of the nail fold. The proximal and lateral nails folds act as a banner, or seal, between the nail plate and the surrounding tissue.
Pseudomonas bacterial infection can occur between the natural nail plate and the nail bed, and/or between an artificial nail coating and the natural nail plate. Many people have been led to believe that the classic ‘green’ discoloration of this type of infection is some type of mold. In actually, mold is not a human pathogen. The discoloration is simply a by-product of the infection and is caused primarily by iron compounds.
