Question 1
Explain how have multidrug resistant pathogens in health clinics been propagated.
Your Answer:
For quite a long time, the first course of treatment for illnesses was use of an antibiotic. Health care
providers prescribed antibiotics regardless whether they were actually able to diagnosis the illness
be it
viral or bacterial or some other disease process. This chronic overuse over time led
to bacteria
mutating and subsequently developing a resistance. Over time more pathogenic
bacteria arose with
the same type of resistance, making the standard antibiotic treatment no longer
an option, as it no
longer would effectively work.
For many years, the first course of treatment for illness
was antibiotics. Health providers
would use these drugs regardless of being able to
diagnose illnesses as bacterial, viral, or
something altogether different. Over time, the overus
e of antibiotics led to bacteria that
accrued mutations leading to resistance. Event
ually more pathogenic bacteria arose with
the
same resistance, and standard antibiotic treatment
no longer worked.
, Question 2 5/5pts
Two auxotrophic bacterial strains are propagated in the laboratory, one deficient
for leucine and the
other deficient for biotin. When cultured alone. they cannot grow on minimal medium,
and when
combined in the same culture media, they still cannot grow in the minimal media. Can you tell
if
genetic transmission occurred in this experiment in the case of genes that control synthesis of biotin or
leucine?
Your Answer:
It does not appear that a genetic transmission occured in the experiment involving these genes
because even with having direct contact there is no growth for either one of the autotrophs.
It does not appear that genetic transmission has occurred in this experiment involving these
genes because even with direct contact, there is no growth rescue for either of these
auxotrophs.
