D311 Microbiology Exam Questions with|\ |\ |\ |\ |\
answers
Which vaccine type has the advantages of producing long-lasting
|\ |\ |\ |\ |\ |\ |\ |\
cellular and humoral immunity and allowing transmission to
|\ |\ |\ |\ |\ |\ |\ |\ |\
contacts?
live attenuated
|\
3 |\multiple |\choice |\options
Broad-spectrum antibiotics disrupt the microbiome and provide |\ |\ |\ |\ |\ |\ |\
an opportunity for pathogens such as Clostridium difficile to grow
|\ |\ |\ |\ |\ |\ |\ |\ |\
and cause infection. How can the microbiome be quickly
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
reestablished to prevent a Clostridium difficile infection? |\ |\ |\ |\ |\ |\
fecal transplant |\
3 |\multiple |\choice |\options
When would it be best to treat a patient with a narrow-spectrum
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
antimicrobial rather than a broad-spectrum antimicrobial? |\ |\ |\ |\ |\
when the infectious agent has been identified as a gram-negative
|\ |\ |\ |\ |\ |\ |\ |\ |\
bacterium

|\ |\ |\ |\ |\ |\ |\ |\ |\
the endocarditis?
|\
a focal infection
|\ |\

A student in a lab has just completed an endospore stain of
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
Bacillus anthracis and realized that heat was not applied during
