4. What are the different types of antimicrobial susceptibility testing methods?
Answer:
- Disk diffusion method
- Etest method
- Broth microdilution method
5. How do you interpret the results of an antimicrobial susceptibility test?
Answer:
- The results of an antimicrobial susceptibility test are interpreted by comparing the size of the inhibition zone around each disk to the established breakpoints for that organism and drug.
- Organisms that are susceptible to the drug will have an inhibition zone that is equal to or greater than the breakpoint.
- Organisms that are resistant to the drug will have an inhibition zone that is less than the breakpoint.
6. What are the different types of quality control measures that are used in a microbiology laboratory?
Answer:
- Positive and negative controls are used to ensure that the reagents and procedures are working properly.
- External proficiency testing programs are used to compare the results of a laboratory to those of other laboratories.
- Internal quality control measures, such as the use of control charts, are used to monitor the performance of the laboratory over time.
7. What is the role of a microbiology technologist in infection control?
Answer:
- Microbiology technologists play a vital role in infection control by performing laboratory tests to identify and characterize infectious organisms.
- They also provide consultation and training to healthcare providers on infection control practices.
8. What are the different types of emerging and re-emerging infectious diseases?
Answer:
- Emerging infectious diseases are new diseases that have recently appeared in humans, while re-emerging infectious diseases are diseases that have been around for many years but have recently become more common.
- Some examples of emerging infectious diseases include SARS, MERS, and Zika virus.
- Some examples of re-emerging infectious diseases include tuberculosis, measles, and whooping cough.
9. What is the importance of antibiotic stewardship?
Answer:
- Antibiotic stewardship is important to prevent the development of antibiotic resistance, which is a major public health threat.
- Microbiology technologists can play a role in antibiotic stewardship by providing information to healthcare providers about the appropriate use of antibiotics.
10. What are the different career opportunities for a microbiology technologist?
Answer:
- Microbiology technologists can work in a variety of settings, including hospitals, clinics, reference laboratories, and research institutions.
