Serratia marcescens is ubiquitous. It is commonly found in soil, water, plants and animals. It is widely present in non potable water in underdeveloped countries due to poor chlorination. This microorganism is a common agent responsible for contamination of Petri plates in laboratories, and is also found to grow on bread [22]. Although S. marcescens is a pathogenic microorganism, it is only so with immunocompromised individuals such as those found in hospitals where many of the documented infections take place. The mode of transmission of this microorganism is by either direct contact,or by catheters, droplets, saline irrigation solutions, and other solutions that are believed to be sterile
