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
