2 disease could be Stroke and Trauma
Answer: See table in the attachment.
Explanation: 1) The <u>Parallel</u> <u>Dilution</u> <u>Formula</u> is given by:
where:
C is concentration
V is volume
For the given data, index 1 represents the concentration and volume of the stock solution and index 2, the concentration and volume of the diluted solution. For example:
= 5 μL
= 7.5 μL
= 10 μL
= 12.5 μL
= 15 μL
= 17.5 μL
= 20 μL
Substituing 
for each concentration given and find each volume needed.
The results is shown in the second column of the table.
2) The stock and total volume is determined. So, to calculate the volume of water needed:
= 100 - 5 = 95 μL
= 100 - 7.5 = 92.5 μL
= 100 - 10 = 90 μL
= 100 - 12.5 = 87.5 μL
= 100 - 15 = 85 μL
= 100 - 17.5 82.5 μL
= 100 - 20 = 80 μL
As shown in the third column of the table.
Answer: The information suggests that C. difficile is the leading cause of hospital-acquired infections usually as a result of antibiotics use.
Explanation: Antibiotics are employed to inhibit or kill bacteria. When used properly, they target aggressive bacteria that are causing infections. But sometimes healthy gut bacteria are killed in the process (normal healthy gut bacteria helps keep C. difficile in check) creating a vacuum which with increasing frequency, C. difficile seizes, and proliferates — especially in hospitalized patients, many of whom are not so strong to withstand the stress of diarrhea and fever.
Some of these antibiotics that most often lead to C. difficile infections include the quinolones, cephalosporines etc. including some proton-pump medications.
