^aTotal number of resistant colonies in a treatment group divided by total number of mice in that group.

^bUT, untreated (mice were given water [vehicle control]).

^cNAC (500 mg/kg body weight) was given once daily for a period of 2 weeks by oral gavage.

^dMoxifloxacin (MOXI; 50 mg/kg body weight) was given once daily for a period of 2 weeks by oral gavage.
