A burn is an injury to skin or tissues of the body caused by heat, electricity, cold, chemicals, and radiation. Pseudomonas aeruginosa (gram-negative bacteria) and methicillin-resistant Staphylococcus aureus (gram-positive bacteria) cause burn infections in humans. Burn causes breathing problems and redness of the skin, damage to blood vessels causes' skin to become black or brown with no blisters. Burn can be diagnosed by examination, depth of a wound, or its associated infections. In developed countries “treatment” cannot be difficult as much as in underdeveloped countries. This is because of lack of awareness or poor income in underdeveloped countries they depend on traditional treatment which left scars of a wound.
