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 different types of scars that may occur with a burn. Keloid scars are caused by an overproduction of scar tissue.The pink or tan keloids commonly thicken and grow beyond the burn injury. Keloids commonly are raised with a dome-like top and can be unsightly.here are different types of scars that may occur with a burn. Keloid scars are caused by an overproduction of scar tissue.
