OBJECTIVE To develop and evaluate a competitive ELISA (cELISA) specific for detection of antibodies to abortion strains of Chlamydia psittaci and C pecorum that is based on monoclonal antibodies against the 2 segments. PROCEDURA: Monoclonal antibodies were screened for binding to ELISA plates coated with elementary bodies, and were selected on the basis of(More)
Protective monoclonal antibodies (MAbs) to the major outer membrane protein (MOMP) of species of the family Chlamydiaceae, which is the primary vaccine candidate antigen, recognize nonlinear epitopes conferred by the oligomeric conformation of the molecule. Protective MAbs failed to recognize oligomeric MOMP of the variant strain LLG, which bears amino acid(More)
The HPB12 protein from the nucleoid of Bacillus subtilis was previously described, and its DNA binding properties have been reported previously (V. Salti, F. Le Hégarat, and L. Hirschbein, Biochim. Biophys. Acta 1009:161-167, 1989). The DNA-HPB12 complexes were examined by electron microscopy. They appeared as short, slightly curved rods whereas naked DNA(More)
The Bacillus subtilis HPB9 is the major heat-stable and acid-soluble protein associated with the nucleoid isolated at low ionic strength. The abundance of the protein in the cell is estimated to about 20,000 monomers per cell (Salti et al. (1985) J. Gen. Microbiol. 131, 581-590). The protein cross reacts specifically with the antiserum against the Bacillus(More)
