FIG. 2.

Rates of antimicrobial resistance of Salmonella serovar Heidelberg isolates from ground turkey (A) and chicken breast (B) in 2002 to 2006. Antimicrobial resistance rates are presented for tetracycline (Tet), sulfonamides (Sul), streptomycin (Str), kanamycin (Kan), gentamicin (Gen), ampicillin (Amp), amoxicillin-clavulanate (Amc), ceftiofur (Tio), cefoxitin (Fox), chloramphenicol (Chl), and nalidixic acid (Nal). Trimethoprim-sulfamethoxazole resistance (not shown) was detected in only two chicken breast isolates in 2006. All isolates were susceptible to amikacin, ceftriaxone, and ciprofloxacin.
