A comparison of different antibiotic regimens for the treatment of naturally acquired shigellosis in rhesus and pigtailed macaques (Macaca mulatta and nemestrina).

Single-dose CCFA, single-dose azithromycin, and a 5-day tapering course of azithromycin all performed as well as a 7-day course of enrofloxacin in eliminating Shigella infection. Fecal PCR may be a better diagnostic than culture for Shigella.
