Textbook Question
Chapter 20, Problem 1CT
If a cut or scrape becomes infected, Staphylococcus aureus is probably the culprit (right). These bacteria often live on the skin and they can cause a problem if they get into a wound. Most “staph” infections can be cured with the antibiotic methicillin. Unfortunately, methicillin-resistant S. aureus (MRSA) is on the rise. Previously, antibiotic-resistant staph infections occurred mainly in hospitals and nursing homes. Now they are breaking out in schools and health clubs. The bacteria are transmitted by contact with an infected person or something that person has touched, as by sharing towels and razors. The gene conferring methicillin resistance is on a plasmid. Explain why a gene that is on a plasmid can spread more quickly than one on the bacterial chromosome.
