Be. Langlois et Ka. Dawson, Antimicrobial resistance of gram-negative enteric bacteria from pigs in a nonantimicrobial-exposed herd before and after transportation, J FOOD PROT, 62(7), 1999, pp. 797-799
Loading pigs onto trucks and transporting them for 30 min resulted in a sig
nificant increase in proportion of antimicrobial resistance of gram-negativ
e enteric bacteria in fecal material. Similarly, the mean number of antimic
robial agents in the resistance patterns of these bacteria increased during
loading and transportation. However, the increases were of a transient nat
ure, as resistance values were similar to those of a nontransported control
group 1 day after the pigs had been transported.
