Novel vaccines and serotyping scheme for Haemophilus parasuis. Glasser's disease, caused by the bacterium Haemophilus parasuis, is a significant problem in Australian and overseas pig industries. Current approaches to the management of Glassers disease utilise antibacterials and also vaccines. However, antibacterials are of limited effectiveness in juvenile pigs (weaners) that are difficult to medicate other than by injection, and current vaccines are only protective against the serotypes included in the vaccine. We propose to examine the immune response to natural infection and identify potential vaccine candidates which will then be tested in vaccine trials. The APAI will focus on developing a DNA-based typing scheme for H. parasuis.
