Protein and antigenic profile among Mycoplasma bovis field strains isolated in Bosnia and Herzegovina

Abstract

Mycoplasma bovis is a serious, worldwide-spread but often overlooked pathogen causing respiratory disease, mastitis, and arthritis in cattle. In this study we characterize the protein and antigenic profiles of M. bovis field strains isolated in Bosnia and Herzegovina by sodium dodecyl sulphate polyacrylamide gel electrophoresis and immunoblotting, and analyze possible variations among these strains. Greater differences occurred when comparing field strains with the reference strain PG45. One field strain isolated from lung samples of a heifer was markedly different from strains isolated from nasal swabs taken from cattle raised in another geographic region. A possible correlation may exist between protein and antigen profiles of M. bovis field strains, geographic regions and anatomical sites of isolation.
