An Effective Approach at Preventing Pinkeye

Moraxella bovis: A bacteria called M. bovis is known to be a major cause of pinkeye. Vaccines such as BOVILIS® PILIGUARD® PINKEYE, AND BOVILIS® 20/20 VISION® 7 WITH SPUR help protect against this pathogen.

Moraxella bovoculi: A recent study found that up to 80% of pinkeye cases were found to include M. bovoculi alone or along with M. bovis.1 MORAXELLA BOVOCULI BACTERIN can help protect against this secondary pathogen.

It Takes Two: Utilizing a combination approach and vaccinating against both M. bovis and M. bovoculi can help your herd gain the maximum protection they need against pinkeye.
