Research Note: Antimicrobial Resistance of Gram-Negative Enteric Bacteria From Pigs in a Nonantimicrobial-Exposed Herd Before and After Transportation

摘要

Loading pigs onto trucks and transporting them for 30 min resulted in a significant increase in proportion of antimicrobial resistance of gram-negative enteric bacteria in fecalmaterial. Similarly, the mean number of antimirobial agents in the resistance patterns of these bacteria increased during loading and transportation. However, the increases were of a transient nature, as resistance values were similar to those of a nontransported control group 1 day after the pigs had been transported.
