QUESTION 5 Place Koch's postulates in sequence from beginning to end. The pathogen must be isolated from the inoculated animal and must be shown to be the original organism. The same pathogen must be present in every case of the disease. The pathogen from the pure culture must cause the disease when it's inoculated into a healthy lab animal. The pathogen must be isolated from the diseased host and grown in pure culture. QUESTION 6 Which of the following is NOT an effective way to control HAls? Sterilization of instruments Handwashing Formation of infection control committees Increasing numbers of compromised hosts

Explanation / Answer

5. Koch's postulates:
i. The pathogen must be present in every case of the disease and not in healthy individuals
ii. The pathogen must be isolated from the diseased host and grown in pure culture
iii. The pathogen from the pure culture must cause the disease when its inoculated into a health lab animal
iv. The pathogen must be isolated from the inoculated animal and must be shown to be the original organism

6. Option D is correct.
HAI = Hospital-acquired infections
If we increase the number of compromised hosts/patients in a hospital, the incidence of HAI increases.
