Robert 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 disease

Note that it is not appropriate to self-diagnose outside of a medical context and this is a completely hypothetical scenario. Imagine you have a rash on your foot. You're concerned that it's an infection and inoculate a sample onto an agar plate. You wonder, How can I figure out whether the pathogen is a bacterium vs a eukaryote? You decide to use lab supplies to get a basic understanding of the pathogen. Be specific about what tests you use and what you expect the results to be. Limit yourself to experiments we could do in our lab. What is one experiment you could do, involving culturing the organism?

Many visits to your physician do not result in a culture or a drug-test of the causative infectious agent, yet you still leave with a prescription for antibiotics. Name one instance where it would be best to be prescribed a narrow spectrum antibiotic. Name a second instance where it would be best to be prescribed a broad spectrum antibiotic.
Which of the following is not a condition of Koch’s postulates?a. isolate the causative agent of a diseaseb. cultivate the microbe in a labc. inoculate a test animal to observe the diseased. test the effects of a pathogen on humans
Below are a list of virulence factors/ strategies paired with an example of an organism that utilizes them. How do each of the following strategies contribute to the virulence of the pathogen? Strategy - Causes the host to produce more receptors (Organism - Rhinovirus) Strategy - Produces gas as a product of fermentation (Organism - Clostridium perfringens) Strategy - Produces a capsule (organism - Klebsiella pneumonia) Strategy - Ability to move between adjacent cells (organism - Cytomegalovirus) Strategy - Ability to use pilus as a motility structure (organism - Pseudomonas aerogenosa)
Define the following terms: Principle of Totality Mutilation Sterilization Plastic surgery Organ Transplantation
Identifying an unknown bacterium is an essential step in the diagnosis and treatment process. Since not every antibiotic is effective against every type of bacteria, knowing what caused a particular infection allows us to make correct prescriptions so patients can recover more quickly. Knowing the cause of an infection also prevents antibiotic resistance as well, since incorrect prescriptions allow bacteria to be unnecessarily be exposed to antibiotics, increasing the chances of developing resistance.
Which of the following statements reflects the pathogenesis of influenza virus? A-The virus frequently establishes persistent infections in the lung B-Viremia is common C-The virus enters the host in airborne droplets D-Viral infection does not kill cells in the respiratory tract E-Pneumonia is not associated with secondary bacterial infections
What is the Germ Theory of Disease? List the contributions of Louis Pasteur, Robert Koch, and Joseph Lister in the germ theory.
Which of the following is NOT true of bacterial exotoxins? Important in the pathogenesis of many human diseases Their toxic effect can be systemic, affecting cells distant from the primary site of infection None of the other four answers (All are true of bacterial exotoxins) Different exotoxins may affect different types of cells (e.g., nerves, gastrointestinal mucosa) Some exotoxins have two components, A (active) and B (binding)
Which of the following pathogens is the LEAST virulent? 1. Microbe B, ID50 = 1,000 cells 2. Microbe D, ID50 = 10 cells 3. None of the other four answers (Cannot be determined from information provided) 4. Microbe C, ID50 = 100 cells 5. Microbe A, ID50 = 100,000 cells
List three viral and three bacterial human diseases and give ONE fact about each. Disease Name, Viral or Bacterial ONE fact about it
