The antibiotic used to fight the body's bacteria and classified as a quinolone is Floxin.

Explanation:

Floxin is the commercial name of Ofloxacin, a 2nd generation quinolone used in the treatment of infections by gram positive and gram negative germs.  Its mechanism of action is to inhibit enzymes important for bacterial development, such as DNA gyrase and Topoisomerase IV.

Ofloxacin can be used for infections of the eyes, ears, skin and genitourinary system, including some sexually transmitted infections.  Other 2nd generation quinolones are ciprofloxacin and norfloxacin.

Ofloxacin comes in tablets form, so it is only administered orally.

    C. Vibramycin is doxycycline, an antibiotic, but of the tetracycline family.
