Abstract

A Mycoplasma hyopneumoniae clone bank was screened with hyperimmune pig serum. One clone exhibited sequence homology to the prokaryotic R2 subunit of ribonucleotide reductase and was expressed as an 11-kDa protein fused to beta-galactosidase. The vaccine potential of the fusion protein was assessed in pig trials. Following experimental challenge with a virulent isolate of M. hyopneumoniae, gross lung pathology (mean Goodwin lung score) of vaccinated animals, irrespective of adjuvant treatment, was significantly reduced compared with that of control unvaccinated pigs (P < 0.05).
