Testing statistical equivalence of the estimates of phenotypic antimicrobial susceptibility of nontyphoidal Salmonella enterica subsp. enterica isolates from urine (n = 144), fecal (n = 1,495), and blood (n = 181) samples of humans in the United States in 2015. (A) Urine versus blood isolates; (B) fecal versus blood isolates; (C) urine versus fecal isolates. The data were collected by the NARMS. Aminoglycosides: GEN, gentamicin; STR, streptomycin. β-Lactam aminopenicillins: AMC, amoxicillin-clavulanic acid; AMP, ampicillin. β-Lactam cephems: FOX, cefoxitin; TIO, ceftiofur. Macrolides: AZI, azithromycin. Phenicols: CHL, chloramphenicol. Quinolones: CIP, ciprofloxacin; NAL, nalidixic acid. Sulfonamides: FIS, sulfisoxazole. Tetracycline: TET, tetracycline.
