Outer membranes were isolated from bovine isolates and type strains of Moraxella bovis, M. phenylpyruvica, M. lacunata, and M. ovis by sodium N lauroyl sarcosinate extraction and differential centrifugation. Analysis of outer membranes from these organisms by sodium dodecyl sulfate-polyacrylamide-gel electrophoresis revealed that all M. bovis isolates shared a common polypeptide pattern that was readily distinguishable from other Moraxella spp. Nine major outer membrane protein bands were identified by sodium dodecyl sulfate-polyacrylamide-gel electrophoresis analysis of M. bovis. Immunoblotting of protein antigens of M. bovis revealed several outer membrane proteins that seemed to be common antigens of all M. bovis isolates.
