In the early part of the 20th century, Serratia marcescens was considered a non-pathogenic organism and was used in medical experiments and as a biological warfare test agent [1]. Since the mid-1970s, however, Serratia species have been recognized to cause a full spectrum of human clinical disease. Additionally, Serratia species may harbor multidrug-resistance mechanisms that can complicate treatment decisions. This article will review the microbiology, epidemiology, clinical features, diagnosis, and treatment of infections caused by Serratia species.
Scar tissue is the formation of fibrosis connective tissue that is created to act as a protective barrier. It replaces healthy tissues that have been damaged due to a number of reasons. Scar tissue generally forms in muscles, tendons, ligaments, fascia, and joints. It is also called an adhesion.
Though scar tissue is made up of the same substance as undamaged skin, it looks different because of the way the fibers in the tissue are arranged. Scars form every time the skin is damaged beyond its first layer, whether that damage comes from a cut, burn, or a skin condition like acne or a fungal infection.
