Bo Norby's primary research interests include the control and management of infectious diseases in food producing animals at the population level, as well as understanding how antibiotic resistance develops in animal agriculture operations and developing novel intervention strategies. Norby is currently leading a team to understand the complex interaction between livestock, livestock management and livestock environments in the development of antimicrobial resistance bacteria.

Veteran Instincts: Teaching the next generation of scientists

MSU Today  online


Having joined the MSU College of Veterinary Medicine in 2011, Bo Norby, associate professor in the Department of Large Animal Clinical Sciences, has already begun to distinguish himself in his field. In June, Norby was invited to attend the White House One Health Forum on Antibiotic Stewardship, a national effort to combat the development of pathogen resistance to conventional drugs. He attributes such successes, in part, to meeting supportive colleagues and heeding their advice.Bo Norby “You need to have good mentors,” he said. “It doesn’t have to be someone you work closely with, but you need to find people willing to teach you the ins and outs of being a new faculty member.” A good mentor, Norby said, can help a new scientist make connections with leaders in his/her department, college and/or field. Mentors can also be important advocates for new faculty members as they begin their ascent through the ranks of tenure and promotion by helping them find a place within large multidisciplinary projects. “A good mentor can help you appraise the projects you’re becoming involved in and make sure there’s a place in them carved out for you that you can make your own,” Norby said. “Especially when you aren’t the principal investigator on a project, it’s important for your career that you have something at the end of it that’s yours.”

The sensitivity of gross necropsy, caudal fold and comparative cervical tests for the diagnosis of bovine tuberculosis

Journal of Veterinary Diagnostic Investigation

2004 Bovine tuberculosis (bTb) was diagnosed in 22 cattle herds in the northeast corner of Michigan's lower peninsula. Of these 22 herds, 494 animals in 7 herds were examined by gross necropsy, histopathologic exam, mycobacterial culture, and polymerase chain reaction (PCR) assay performed only on samples that were histologically compatible for bTb.
