Introduction

Antibiotic resistance is the abilty of a microorganism to withstand the effects of antibiotics. One of the first antibiotic resistant bugs was Staphylococcus. Scientists are dismayed to discover that some bacteria have become resistant to antibiotics through various alterations, or mutations, in their DNA. Hospitals have become a major breeding ground for antibiotic resistant bacteria. These bacteria muiltiply in an environment full of sick people who have poor immune systems and where antibiotics have eliminated competing bacteria that are not resistant.
