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.
Scar, mark left on the skin after the healing of a cut, burn, or other area of wounded tissue. As part of the healing process, specialized cells called fibroblasts in adjacent areas of skin produce a fibrous connective tissue made up of collagen. The bundles formed by these whitish, rather inelastic fibres make up the bulk of the scar tissue.
