Antimicrobial susceptibility of bovine respiratory disease isolates obtained from Australian feedlots (2014-2018)

Efficiency‐corrected PCR quantification for identification of prevalence and load of respiratory disease‐causing agents in feedlot cattle

“…The incidence and prevalence of BRD in cattle can be influenced by many factors. These include pre‐exposure to viral or bacterial organisms 8 ; vaccination history 9 ; backgrounding 10 ; co‐mingling of non‐consanguineous cohorts 11 ; time on feed 12 ; antimicrobial resistance 13 ; seroconversion 12 ; transportation time to the feedlot 14 and the presence of other co‐morbidities and other undetermined factors 15 . Environmental risk factors such as the time of year of entry to the feedlot (also known as feedlot induction), the region, prevailing weather conditions, 16 source of the cattle, cattle breed and induction weight have all been positively correlated with BRD risk 17 .…”
