TMW # 8 Chapter 22 Why do patients with methicillin-resistant Staphylococcus aureus (MRSA) as part of normal nasal microbiota pose a risk to other patients in a hospital In a healthy person the normal microbiota limits the infection and disease by other pathogens via competing for space and nutrients with other invading organisms. The patients in hospitals are at risk for opportunistic infections because of their impaired immune system. Why must diphtheria immunization be boosted every 10 years? Because humans are the only known host for C.diphtheriae , the best way to prevent this disease is through immunization.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
