Question 14 If a suspect bacterial pathogen infecting your patient is known to be "fastidious" which medium would you grow this pathogen on? selective media such as MacConkey agar enrichment medium such as blood agar differential medium such as MSA O all purpose medium such as SAB Question 15

Question 39 Match the description to the correct phase in a standard bacterial growth curve best time to perform Gram stains [Choose] [Choose ] phase in which one would see the highest stationary phase concentration of endospores death/decline phase phase in which bacteria are most sensitive to lag phase antibiotics log/exponential stage many bacteria in biofilms are in this phase, thus are more resistant to antibiotics [ Choose ] stage at which "carrying capacity" is reached [ Choose ] phase in which bacteria are adjusting to new environment, synthesizing proteins, copying DNA in preparation for division [ Choose] phase when generation time/doubling time is [Choose] calculated

Question 11 When treating bacterial meningitis, which of the following drug classes should be co-administered with antibiotic therapy? Question 11 options: a) Beta-blockers b) Antiviral medications c) Antiseizure medications d) Dexamethasone, a corticosteroid drug

Practice Question #2 Each of the following statement FALSE. Tell me what is incorrect with the statement and correct it when possible. For example, if the statement says: the sky is red during daytime. You would answer: the sky isn't red during daytime, it is blue. a) Your lab supervisor asks you to grow a new bacterium they got from a collaborator. You grow them in the suggested nutrient-rich media, and you notice that as the log phase growth progresses, the bacteria seem to turn purple. You mention it to your supervisor and ask whether it is the gradient from very high to low nutrient bioavailability that induces metabolic changes which induces the production of a purple pigment. Your supervisor tells you that is unlikely. What is a more plausible conclusion? Note: The metabolic changes statement is wrong, the "plausible conclusion" is this case is the correction of the false statement, conclusion. the more plausible b) The organism in Tube B is microaerophilic.
