61) The peak of the disease, when you would experience the most intense signs and symptoms, is known as the acute or invasive phase. 60) The phase when tissue healing and repair occurs is the convalescent phase. 59) Coronaviruses replicate in bats and can be passed on to humans. Bats are considered a reservoir for coronaviruses. 58) An animal, such as an arthropod, that transmits a pathogen from one host to another is a vector. 57) Which of the following is NOT true of Koch's postulates? It requires isolation of the causative agent. The suspected causative agent must be present in every case of the disease. It requires inoculation into a healthy, but susceptible host. It can be applied to fastidious organisms.

30. Which of the following would be considered the MOST important for the establishment of an infection? - Virulence factors - Quorum sensing - Host cell receptors that are recognized by adhesins (products used for attachment) - Evasion 31. If a disease affects a human and NOT an animal, then it would be difficult to fulfill Koch's postulate number: - 1 - 2 - 3 - 4 - None of the above 32. The practice of deliberately stimulating the immune system is called: - Acquired immunity - Memory immunity - Vaccination - Hypersensitivity 33. Vaccination eliminates diseases such as smallpox and polio by: a. Eliminating susceptible hosts b. Curing infected people c. Killing the pathogens that cause smallpox and polio d. All of the above
- term can differentiate between the strains. - Pathogenicity - Virulence - Both Sandy B - None of the above - A communicable disease that is easily spread from one individual to another. 1) Communicable diseases 2) Contagious diseases 3) Non-communicable diseases 4) None of the above - It is true regarding the normal microbial flora present on the skin and mucous membranes that. 1) It cannot be eradicated by antimicrobial agents 2) It is absent in the stomach due to the acidic pH 3) It establishes in the body only after the neonatal period 4) The flora in the small bronchi is similar to that of the trachea
