Abstract

Expression library immunization (ELI) has previously been used in a number of disease models in mice. Here, we describe the first example of the application of ELI to a large animal model with the immunization of pigs against enzootic pneumonia, a disease caused by Mycoplasma hyopneumoniae. The development of new plasmid vectors and library screening methods facilitated the application of ELI to this disease by allowing random libraries to be screened for clones expressing recombinant proteins. In this way the vast majority of clones in random libraries that are unproductive can be eliminated, meaning that libraries are more likely to give protection and are subsequently easier to further screen and analyze. By using this approach we have used one library screen and two animal trials to progress from an original library of 20,000 clones to a group of just 96 clones.
