Interpretive Summary: Mycoplasma gallisepticum causes significant economic loses for poultry producers. While vaccines exist, the information needed to effectively apply those vaccines is lacking. This study tested commercially available diluents for use during eye drop vaccination with live Mycoplasma gallisepticum vaccines. The results of this work showed that using any of the diluents tested with commercial vaccine would provide protection from Mycoplasma gallisepticum infection when delivered by eye drop.

Technical Abstract: Direct eye drop vaccination of poultry using live Mycoplasma gallisepticum vaccines provides the most efficient route of vaccination. The research reported in this study examines the effect of diluent used to rehydrate lyophilized M. gallisepticum vaccines on its ability to induce a measurable humoral immune response in the host. The results suggest that during the initial time period following vaccination, significant differences between the diluent treatment groups are found. However, these differences between the diluents are unlikely to significantly impact the final outcome of vaccination when considered over the life of the host.
