- Which of the following statements is incorrect? a. Mucosal surfaces are better than skin surfaces at supporting colonization by commensal microorganisms. b. The skin provides a larger surface area than mucosal surfaces for commensal microorganisms. c. There are ten times as many bacteria residing in the intestinal tract than the number of cells in the human body. d. It is common for commensal bacteria to live in symbiosis with their human hosts. e. During gestation in mammals, a fetus does not have any commensal microorganisms on their skin or mucosal surfaces.arrow_forwardWhich of the following statements is correct? a. An individual who has been diagnosed with a communicable disease and those who may have been exposed to the infection are to be placed together in a unit away from others b. Serial interval is the interval between when an infectious agent invades a body and when the first sign or symptom appears c. Isolation should be maintained through the incubation period of a disease d. Healthy asymptomatic individuals suspected to have been exposed to an infection are quarantined through the length of the incubation periodarrow_forwardWhy antibacterial drugs are ineffective against: A.

- Choose the false statement: O A contaminated catheter might be an example of an iatrogenic infection. The size of an inoculum introduced into the host has little to do with the success or pathology of an infection. O A zoonosis is an infectious disease or pathogen that has crossed over from an animal species and begun to infect humans. O Vertical infections are those transferred from mother to child either during birth or via breastfeeding. Question 21 Choose the false statement below. O Long term consequences to a host that have been caused by infectious disease (such as heart disease after septicemia) are termed sequelae. OPortal of exit" refers to the way in which the immune system destroys an infection, or how antibiotics can be used to kill invading bacteria. O Whether or not a person is a susceptible host for disease is determined in part by where that person lives and how that person is employed.arrow_forwardAn apple grower notices that several of his apple trees with fungi growing on their trunks have developed necrotic ring spots, while other trees in the orchard that lack fungi appear healthy. What is the most likely conclusion the farmer can make about the virus infecting his apple trees? a. The apple trees were infected by horizontal transmission. b. The fungi carry disease. c. The fungi attract disease-carrying insects. d. The apple trees were infected by vertical transmission.arrow_forwardJohn Smith is a pig farmer. For the past five years, Smith has been adding vitamins and low doses of antibiotics to his pig food; he says that these supplements enhance the growth of the pigs. Within the past year, however, several of his pigs died from infections of common bacteria, which failed to respond to large doses of antibiotics. Can you explain the increased rate of mortality due to infection in Smith’s pigs? What advice might you offer Smith to prevent this problem in the future?arrow_forward

- The epidemiological or disease triangle is a model of disease causation that proposes three factors contribute to an outbreak – an agent that causes the disease, a susceptible host, and an environment that brings the host and agent together. Some general changes within these three factors that may cause an infectious disease to emerge include: A. changes in populations or behavior of reservoir hosts or intermediate hosts B. microbial genetic mutation and viral genetic recombination or assortment C. environmental factors such as an increase in precipitation D. all of the above E. none of the abovearrow_forwardWhich of the following statements correctly describes exotoxins and endotoxins produced by various bacteria?
