Multiplex-PCR detection method for Pasteurella multocida and Haemophilus parasuis had been developed based on published single PCR for these pathogens. The PCR reagents, annealing temperature and the PCR procedure were optimized and the primers were screened, the PCR products including 457bp of PM and 1090bp of HPS were obtained just by one test.

Methods Acanthamoeba polyphaga and Legionella pneumophila were co-cultured under laboratory condition. At consecutive time points during the culture, smears of the cultured products were made on glass slides for staining purposes. Different types of stainings including Gram′s staining, Gimenez staining, Giemsa staining and immunofluorescence were used to determine the best method for the identification of amoebal pathogens.

By using multi-dimensional nuclear magnetic resonance method we have studied the folding mechanism of staphylococcal nuclease in vitro; the tertiary interactions for folding of SNase fragments into native-like conformation; the interaction between SNase N- and C-terminal subunits; the relationship of enzyme activity with folding and dynamic states of SNase; the structural properties of enzyme protein while exert its function. We have studied the internal motions of thermophilic Archaea protein Ssh10b and mechanism of its heat-resistance using the NMR 1H-15N relaxation and H/D exchange methods. We have determined the 3D solution structure of human translationally controlled tumor protein TCTP and the Ca2+-binding site; determined the 3D crystal structure of human mitoNEET, a novel protein from distinct groups of iron-sulfur proteins; determined the 3D solution structure of a novel chromatin protein Cren7. Determination of SNase-DNA and Archaea protein-DNA complex structures are in progress.
