[prettyting (get a food in the door)]

Mastitis is an infection of the udder in cows that, although not dangerous,

causes them to give poor-quality milk. Most cases of mastitis are caused by

the bacterium Staphylococcus aureus, against which antibiotics are

ineffective. However, a related bacterium, Staphylococcus simulans, quickly clears up

even severeinfections of S. aureus simply by displacing the bacteria.

S. simulans is nevertheless unlikely to become the preferred treatment for

cases of mastitis, since_____.

A. certain dangerous bacteria that normally cannot take hold

can do so in the presence of S. simulans.

B. the current resistance of S. aureus to antibiotics derives in part

from a past pattern of overuse of those antibiotics

C. the milk from cows infected with S. aureus is generally not of

such poor quality as to be entirely unusable

D. careful farming practice can reduce the incidence of mastitis to

a minimum

E. the only symptom of mild cases of mastitis is the deterioration

in the quality of the milk produced

這題答案是A，我當初寫A是因為其他都被我刪光了所以才選這個答案。

想請問各位高手這A選項的翻譯到底要怎麼解釋會比較好阿?

謝謝~

→ prettyting:A的意思是說:這種病毒再S.s存在下會變的更危險嗎?
推 Vinicks:(A)的意思是說某些傷害的細菌一般來說不會存在~~~但是
→ Vinicks:在這種S.simulans狀況下會存在 因此此計畫不可行 因為會
→ Vinicks:產生certain dangerous bacteria....
→ Vinicks:另外certain dangerous bacteria並非指文章出現的...
→ Vinicks:而是某些 但是是哪些就不清楚了 只知道是危險的...
→ prettyting:感謝V大的詳解~^^
