antigen heterogeneity among mycoplasma mycoides subsp. mycoides sc isolates: discrimination of major surface proteins.the protein and antigen profiles of 60 isolates, strains and the type strain pg1 of mycoplasma mycoides subsp. mycoides s.c. were compared by sodium dodecyl sulphate polyacrylamide gel electrophoresis and immunoblot analysis. analysis using contagious bovine pleuropneumonia antisera and hyperimmune rabbit sera against several representative strains revealed some differences in protein profiles and variability in antigens among strains from different geographic regions. the most common antigenic ...19989810618
genetic and serological analysis of the immunogenic 67-kda lipoprotein of mycoplasma sp. bovine group 7.the gene encoding a lipoprotein of 67 kda, named p67, was cloned from mycoplasma sp. bovine group 7 strain pg50 and expressed in escherichia coli k12. analysis of the amino acid sequence derived from the dna sequence of the p67 gene revealed a typical prokaryotic signal peptidase ii membrane lipoprotein lipid attachment site and a transmembrane structure domain in the leader sequence at the amino-terminal end of the protein. protein p67 showed 91% identical amino acid residues to the lipoprotein ...19989766210
