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.
There are many instances in the body where scar tissue will develop. After surgery, scar tissue will develop where the surgical incision is in the skin. If muscles and tendons were cut or repaired, scar tissue will develop there. After injuries like a hamstring tear or rotator cuff tear, scar tissue will develop in the muscle as it heals. Bony scar tissue, called a callus, will form on the bone after a fracture.
