Prevalence and relative abundance of respiratory pathogens in the upper respiratory tract at preconditioning processing. Within each group, six pools of nasal swabs, with five animals per pool, were tested for opportunistic bacterial pathogens at preconditioning processing by qPCR for groups that were treated previously for BRD (MT-1 and MT-2) or those that remained untreated. a Number of pools positive for each bacterial species at preconditioning processing. b Cycle threshold for qPCR positive pools
