2. What is culture and sensitivity (C&S) testing?

• Answer: Culture and sensitivity (C&S) testing is a diagnostic procedure where a sample from an infection site is cultured in a lab to identify the pathogen and determine its antibiotic susceptibility.

3. Which of the following is NOT a portal of entry for pathogens?

• Answer: The Endocrine system is NOT a portal of entry. Common portals of entry include the respiratory, gastrointestinal, and urogenital tracts.

4. What is a fomite?

• Answer: A fomite is a non-living object that can carry and transmit infectious pathogens (e.g., doorknobs, bedding, surgical instruments).

• Answer: The medical term for inflammation of the lungs is pneumonia.

18. What does the term “virulence” mean in relation to pathogens?

• Answer: Virulence refers to the degree of pathogenicity, or the ability of a microorganism to cause disease.

19. What is the term for the study of disease transmission in populations?

• Answer: The study of disease transmission is called epidemiology.

20. What is the term for the collection of bacteria or viruses in a laboratory setting to test their susceptibility to antibiotics?

• Answer: This process is called culture and sensitivity (C&S) testing.
