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.Read moreRead less
Towards the development of a novel live vaccine for the control of Glässer's disease (Haemophilus parasuis), a globally significant respiratory disease of swine. Respiratory diseases are common in intensively housed pigs, costing the Australian industry millions of dollars in lost production annually. Glässer's is a highly contagious and often fatal respiratory disease of pigs. Antibiotic therapy is expensive and often results in the emergence of antibiotic resistant organisms.

Respiratory diseases are common in intensively housed pigs, costing the Australian industry millions of dollars in lost production annually. Glässer's is a highly contagious and often fatal respiratory disease of pigs. Antibiotic therapy is expensive and often results in the emergence of antibiotic resistant organisms. There is also a trend to move away from the use of antibiotics in food production animals. Current vaccines are based on inactivated preparations and do not offer a high level of immune protection. Therefore, there is a great need worldwide for a live vaccine for the effective control of Glässer's disease.Read moreRead less
