Reiterated repeat region variability in the ciliary adhesin gene of Mycoplasma hyopneumoniae.

Mycoplasma hyopneumoniae is a highly prevalent pathogen which colonizes the ciliated epithelial lining of the porcine respiratory tract. Expression libraries constructed from genomic DNA of the non-pathogenic strain M. hyopneumoniae J were screened with porcine hyperimmune antiserum against M.
