Question

multiple choice

1) if we were to identify a strong quorum sensing inhibitor we could use this molecule to do which of the following?
a. bind and neutralize viruses
b. decrease biofilm formation
c. decrease production of bacterial pigments
d. induce cell death
e. increased rates of metabolism in fungi

2) List the microbes in order from most resistant to most susceptible for most CHEMICAL control agents.
a. bacillus endospores, enveloped virus (ebola), mycoplasma, naked virus (d68)
b. bacillus endospores, naked virus (d68),enveloped virus (ebola),mycoplasma
c. bacillus endospores, mycoplasma, naked virus (d68), enveloped virus (ebola)
d. naked virus (d68), bacillus endospores, enveloped virus (ebola),  mycoplasma
e. naked virus (d68), bacillus endospores, mycoplasma, enveloped virus (ebola)

Explanation / Answer

1) Quorum sensing is a bacterial communication mechanism that helps bacteria to develop resistance to the antibiotic. For example, biofilm formation in Streptococcus pneumoniae and penicillinase production in Staphylococcus aureus are a result of quorum sensing. An example of quorum sensing inhibitor is V-06-018. So, the answer for this question is option b (decrease biofilm formation).
