The Shifting Landscape of Pinkeye: Control at the Herd and Regional Level

Farm Journal logo

RACE CE credit available

For many years, Moraxella bovis (M. bovis) was the predominant species of bacteria associated with pinkeye circulating in cattle herds.1 About 15 years ago, however, veterinarians in the field began reporting increased cases of pinkeye due to an emerging species, Moraxella bovoculi (M. bovoculi), which is now more frequently detected than M. bovis.1 This changing landscape has made pinkeye control more complex and difficult for many veterinarians and producers. 

In this webinar, you’ll hear from three veterinarians who have all contributed to successful pinkeye control strategies on different types of operations throughout the U.S.

Dr. Jessica McArt, associate professor in the Department of Population Medicine and Diagnostic Sciences at Cornell University, will discuss her experiences controlling pinkeye in the university’s dairy research herd. She’ll give an overview of how her approach to controlling the disease has changed over the years and go in depth on what’s working for her today.

Dr. Russ Breshears, a veterinarian with Pony Express Veterinary Clinic who works primarily with beef cattle producers in Kansas, will discuss his approach to successfully controlling pinkeye in multiple herds within the same region using frequent diagnostics and custom-made vaccines.

In addition, Dr. Jason Shumaker, technical service veterinarian with Newport Laboratories, Inc., will update viewers on the rapidly changing landscape of pinkeye, outline the critical role diagnostics play in pinkeye control and discuss how he and his team help veterinarians and producers get a handle on this costly disease.
