P31. Assessing The Long Term Effects Of Perceived Predation Risk On The Avian Brain, Lauren E. Witterick
Western Research Forum
Predators affect prey populations not only through direct killing, but also through the perception of predation risk. Responding to predator threats is critical for prey survival, however perceived predation risk can have lasting effects ranging from individual changes in neurobiology up to the population level. My research focuses on the lasting effects of predator ‘fear’ on the avian brain. I will be using auditory playbacks to manipulate predation risk in black-capped chickadees (Poecile atricapillus) in acoustic isolation and brown-headed cowbirds (Molothrus ater) in large outdoor aviaries. Lasting behavioural changes have been found in black-capped chickadees one week after …
P02. Production Of A Protein Subunit Vaccine For Mannheimia Haemolytica In Lettuce Chloroplasts, Coby K. Martin
P02. Production Of A Protein Subunit Vaccine For Mannheimia Haemolytica In Lettuce Chloroplasts, Coby K. Martin
Western Research Forum
The cattle industry worldwide is ravaged by bovine respiratory disease (BRD), a bacterial disease caused by Mannheimia haemolytica. We have designed a chimeric protein subunit vaccine against M. haemolytica based on recent evidence demonstrating the protective potential of antigens against a virulence factor, leukotoxin, in addition to a surface lipoprotein. Plant-based production of this protein vaccine provides a safe and inexpensive alternative to traditional production methods. Plant-base production also supports the use of an edible vaccine that will deliver antigens to pharyngeal tissues to provide local immunization against M. haemolytica to prior to its progression into the lungs. Chloroplasts …
