Study Notes

MDRD and Microbiology

  • MDRD stands for Medical Device Reprocessing and Deals with the sterilization and disinfection of medical devices
  • Microbiology is the study of microscopic organisms, including bacteria, viruses, and other microorganisms
  • Medical Device Reprocessing Technicians (MDRTs) are responsible for following all cleaning, disinfection, and sterilization practices to eliminate pathogenic organisms

Germ Theory of Disease

  • The germ theory of disease states that many diseases are caused by the presence of microorganisms
  • Microorganisms can be found on medical devices and can cause infections if not properly sterilized and disinfected

Chain of Infection

  • The chain of infection includes:
    • Infectious agent (e.g. bacteria, virus)
    • Reservoir (e.g. contaminated medical device)
    • Portal of exit (e.g. contaminated device is used on a patient)
    • Mode of transmission (e.g. direct contact, airborne)
    • Portal of entry (e.g. patient's open wound)
    • Susceptible host (e.g. patient with compromised immune system)

Microbiology Basics

  • Microbiology is the study of microscopic organisms, including bacteria, viruses, and other microorganisms
  • Microorganisms can be beneficial (e.g. bacteria in the gut) or harmful (e.g. bacteria that cause disease)
  • Microbiology is important for MDRTs because they need to understand how to eliminate pathogenic organisms from medical devices

Types of Microbiology

  • Microbial physiology: study of cell growth, metabolism, and cell structure
  • Microbial genetics: study of how genes are organized and regulated in microbes
  • Medical microbiology: study of the role of microbes in human illness
  • Veterinary microbiology: study of the role of microbes in veterinary medicine
  • Environmental microbiology: study of the function and diversity of microbes in the environment

Impact of Infectious Disease

  • Historical examples of infectious diseases include:
    • The Black Death (bubonic plague)
    • Smallpox
    • HIV/AIDS
  • These diseases have had significant impacts on human history and continue to affect populations today

Antibiotic Resistance

  • Antibiotic resistance occurs when bacteria develop ways to resist the effects of antibiotics
  • Antibiotic resistance is often caused by over-treatment of humans and farm animals with antibiotics
  • Antibiotic resistance can lead to the development of "Superbugs" that are resistant to multiple antibiotics
