Abstract

Bovine respiratory disease (BRD) is a multifactorial disorder in which the proliferation of bacterial pathogens may be influenced by pre-exposure to viral pathogens and behavioural and environmental stressors. The role of Mycoplasma bovis in the pathogenicity of BRD, as a non-commensal bacterium, is poorly understood and its recalcitrant nature complicates the detection in clinical samples. To overcome the limitations of conventional culture, we have utilised an absolute quantitative PCR approach (Kishimoto et al. 2017) to improve the detection of M. bovis in feedlot steers. To better understand the prevalence of this organism in the Australian feedlot system, we compared induction to hospital pen animals using qPCR and compared two DNA extraction techniques.

OtherIt is with enormous pleasure that we invite you to Perth, Western Australia for the 33rd conference of the Australian Association of Animal Sciences (formerly Australian Society of Animal Production), which will be held at the Esplanade Hotel in the beautiful city of Fremantle, 1st – 4th February, 2021.
For the last 60+ years this conference has brought together animal production scientists, consultants, extension specialists, producers and students to share information – from blue sky research to practical outcomes. The cross-species forum has allowed researchers to glean knowledge and ideas from outside of their areas of reference and provided an opportunity to communicate with a broad range of animal production specialists.
