Chemical process of decomposition during early decomposition, while others are degraded during later stages of decomposition. During the early stages of decomposition, soft tissue proteins are broken down. These include proteins that: During later stages of decomposition, more resistant tissue proteins are degraded by the effects of putrefaction. These include: Keratin is a protein which is found in skin, hair, and nails. It is most resistant to the enzymes involved in proteolysis and must be broken down by special keratinolytic microorganisms. This is the reason that hair and nails are commonly found with skeletal remains. In general, proteolysis breaks down proteins into: Continuing proteolysis
Skin infection Skin infection Infection of the skin is distinguished from dermatitis, which is inflammation of the skin, but a skin infection can result in skin inflammation. Skin inflammation due to skin infection is called "infective dermatitis." Bacterial skin infections affected about 155 million people and cellulitis occurred in about 600 million people in 2013. Bacterial skin infections include: Fungal skin infections may present as either a superficial or deep infection of the skin, hair, and/or nails. As of 2010, they affect about one billion people globally. Parasitic infestations, stings, and bites in humans are caused by several groups of organisms belonging
