Scatter plot of the minimal inhibitory concentrations (MIC) determined by the agar dilution method to nalidixic acid (NA), amikacin (AMK), amoxicillin (AMX), ampicillin (AMP), cefoxitin (CFX), norfloxacin (NRF), gentamicin (GEN), tetracycline (TET), and trimethoprim-sulfamethoxazole (SMX) of Salmonella spp. (n = 24) strains isolated from fecal samples of calves and the Salmonella spp. (n = 39) strains isolated from fecal samples of pigs in Minas Gerais State, Brazil. Resistant strains are showed in red and intermediate susceptibility profile in yellow. Ellipses indicate the MIC₅₀ for each antimicrobial agent, while dotted rectangles indicate the MIC₉₀
