Question

what are seven infectious diseases of wounds and their infectious agents.

Answer 1

An infected wound is a localized defect or excavation of the skin or underlying soft tissue in which pathogenic organisms have invaded into viable tissues surrounding the wound.Infection of the wound triggers the body’s immune response,causing inflammation and tissue damage,as well as slowing the healing process.

Wounds maybe grouped according to the cause,the environment in which they occur,their extent,and whether they are clean or contaminated.Bacteria,fungi and viruses can cause skin and wound infections.

Most of the infected wounds are caused by bacterial colonization, originating either from the normal flora on the skin,or bacteria from other parts of the body or the outside environment.The most common causative organisms associated with wound infections include staphylococcus aureus/ MRSA,streptococcus pyogens,Entrococci and pseudomonas aeruginosa.

Types of wound Infections and microorganisms

• Superficial skin infections: primarily in the outer layers of the skin but may extend into the subcutaneous layer.Typical bacterial skin infections include Folliculitis,furuncles and carbuncles,Impetigo,Pressure sores,Cellulitis,Necrotizing fasciitis.This type of infections often involves Group A streptococci
• Other common suprficial such as ring worm and athletes foot caused by fungi Trychophyton sp.
• Bites: Wound infection caused by human and animal bites common bacteria is pasteurella multocida
• Truma: it includes from burns to injuries from motor vehicle accidents,crush injuries,cuts from knives and other sharp instruments,and gun shots.These wound infections are caused by more than one aerobic and/ or anaerobic microorganisms such as clostridium tetani
• Post surgical wound infection:deep wounds may become infected with both superficially with aerobic and deeply with anaerobic microorganisms
• Burns: initial infection bacterial.Fungal infections due to candida,Aspergillus,Fusarium,and other species may arise later.
