AB  - A study was conducted to test the hypothesis that strains of Salmonella 
      Typhimurium that are resistant to antibiotics are more resistant to chlorine in 
      chilled water than strains of Salmonella Typhimurium that are not resistant to 
      antibiotics. To test this hypothesis, strains (n = 16) of Salmonella Typhimurium 
      with four antibiotic resistance profiles were tested for their inactivation 
      kinetics in chlorinated (30 ppm, pH 6) water at 4 degrees C. The four antibiotic 
      resistance profiles were (i) none; (ii) tetracycline-sulfisoxazole (T-Su); (iii) 
      tetracycline-ampicillin-amoxicillin-cefoxitin-ceftiofur-sulfisoxazole 
      (T-A-Am-C-Ce-Su); and (iv) 
      tetracycline-ampicillin-amoxicillin-cefoxitin-ceftiofur-sulfisoxazole-kanamycin 
      (T-A-Am-C-Ce-Su-K). Inactivation of Salmonella Typhimurium in chlorinated water 
      displayed nonlinear kinetics with a concave downward curve that fit well (R(2) = 
      0.964) to the power law model, with a shape parameter of 1.37. The time for a 
      single log reduction (D-value) of Salmonella Typhimurium from an initial 
      concentration of 5.36 log/ml did not differ (P > 0.05) among the four antibiotic 
      resistance groups and ranged from 3.8 to 4.3 min for n = 4 strains per group. 
      Thus, the hypothesis was rejected, and it was concluded that expression of an 
      antibiotic resistance phenotype does not confer cross-protection in Salmonella 
      Typhimurium to chlorine inactivation in chilled water.
