^aAbbreviations: A, strain from acute-phase sample; R, strain from relapse-phase sample; MDR, multiple-drug resistant (resistant to chloramphenicol, ampicillin, co-trimoxazole, and tetracycline); Na^r, resistant to nalidixic acid; FS, susceptible to all antibiotics tested; Deg, degraded; UT, untypeable; Var, variant; None, no detectable plasmids. The I-CeuI types are those used by Liu and Sanderson (18).
