Total questions: 14
Worksheet time: 9mins
Look at the Antibiotic Introduction Timeline (1.11A).
Where can you make the following annotation?
"Bacteria showed resistance to the antibiotic the same year it was introduced."
Amoxicillin
Imipenem
Vancomycin
Ciprofloxacin
Refer to the Antibiotic Introduction Timeline (1.11A).
Which antibiotic had bacteria develop resistance before its introduction?
Penicillin
Prontosil
Streptomycin
Ciprofloxacin
What does it mean if resistance was observed for an antibiotic BEFORE it was introduced?
Scientists found some bacteria had already became resistant, but it was still beneficial to start using it to treat some infections.
Scientists found some special bacteria knew ahead of time and were preparing for the release of the antibiotic on the market.
Looking at the Antibiotic Introduction Timeline (1.11A),
Which antibiotic had the longest period before resistance was observed?
Ciprofloxacin
Vancomycin
Imipenem
How many antibiotics does this bacteria seem to be resistant to?
2
3
All of them
None of them
Use the graph 1.11C:
MRSA stands for...
Methicillin-Resistant Staphylococcus aureus
Methicillin-Responding Staphylococcus aureus
Use the graph 1.11C:
VRE stands for...
Vancomycin-Resistant Enterococci
Vancomycin-Reaching Enterococci
Why are the 2 types of bacteria on the graph (1.11C) concerning to health officials?
Both bacteria's resistance to methicillin has increased dramatically.
Both are bacteria and all bacteria are harmful.
The frequency of resistant strains of both bacteria has increased dramatically.
Where was the data in the graph (1.11C) collected?
From the microbiology lab
From doctors offices and medical labs around the country
From patients in hospital intensive care units
Which statement is supported by the graph? (1.11C)
MRSA appeared or was discovered after VRE
% of cases that are antibiotic resistant is increasing at a constant rate
Resistance in Enterococci developed more quickly than in S. aureus
MRSA appeared or was discovered before VRE
Which statement is supported by the graph? (1.11C)
From 1991 - 1996, the rate of increase in antibiotic resistance slowed.
This trend was seen in nonhospitalized patients.
Between 1991 and 1996, there was no resistant bacteria.
