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.
Provide evidence in supporting or refuting the following statement: The cell, or cytoplasmic membrane, is a nonessential structure in bacteria because its function is replaced by the cell wall in these microbes.

In other words, what factors about a microbe or factors about a disease make it impossible for Koch's postulate to be performed with that microbe or disease?arrow_forward
- Which of the following is not part of Koch’s Postulates? a. A specific microorganism must be present in a disease b. The organism must be isolated into pure culture c. Living organisms spring forth from non-living materials d. All of the choices are part of Koch’s Postulatesarrow_forwardWhich of the following describes "incubation period"? a. It is the time interval between entry of an infectious agent into the body and the appearence of the first symptoms and/or signs of the disease b. It is the time after recovery when a person can still harbor the infection c. It is the time interval through which an infected person is able to transmit the infectious agent to others d. It is the time interval between the onset of primary and secondary casesarrow_forwardThe following are the limitations of Koch's postulates EXCEPT: A. some pathogens cannot grow on artificial media and therefore cannot be identified as the causative agent of the disease B. some diseases involve multiple pathogens which produce similar symptoms making it difficult to pinpoint the causative agent C. some diseases are host-specific and re-inoculation may pose ethical concerns D. some microorganisms are present in the body fluids of the infected animal which make them difficult to be culturedarrow_forward
- The objective of this question is to understand the distribution of infectious pathogens, using information from three different scientific articles. Infectious pathogens, which include bacteria, viruses, fungi, and parasites, can be distributed in a variety of ways, including through direct contact, airborne transmission, and vector-borne transmission.arrow_forwardWhy antibacterial drugs are ineffective against: A. Fungal Infections B. Viral infections C. Helminthic worm infectionsarrow_forwardRobert Koch developed a set of criteria (postulates) for conclusively demonstrating the aetiology (specific cause) of an infectious disease. Which of the following is not a postulate? The infectious agent must be isolated and cultured in vitro The disease is reproduced when a pure culture of the infectious agent is inoculated into a new susceptible host The infectious agent can be recovered from the experimentally-infected host The infectious agent is present in most cases of the diseasearrow_forward
- The rate and magnitude of the spread of infectious organisms through populations depends on its mode of transmission and on the infectious agent’s growth characteristics.Describe the portals of entry that pathogenic organisms need to bypass to cause diseases.arrow_forwardPlease provide evidence supporting or refuting the following statement: Humans consume microbes every day with little health risk.arrow_forwardA key result of the pandemic has been the increased scrutiny of scientific research by a broader and, in some cases, a less experienced audience, resulting in significant discussions about the basic tenets of scientific theory and discovery.
