چکیده

The goal of this project is to identify the genes encoding M. gallisepticum F-strain surface proteins recognized by specific antibody reagents to characterize the individual role of each gene product in host colonization. Here we report the characterization of a 70-kDa surface protein recognized by monoclonal antibody 6F10. The surface protein was gel isolated and digested with trypsin for evaluation with mass spectrometry. The results showed that 19 out of the 21 tryptic peptides matched with proteins of the vlhA lipoprotein family. We suggest that monoclonal antibody 6F10 is specific for the predominantly expressed vlhA protein (formerly pMGA) of the F-strain of M. gallisepticum.

The vlhA gene sequencing of Iranian Mycoplasma synoviae isolates

Mycoplasma synoviae expressed variable lipoprotein haemagglutinin (VlhA) is believed to play a major role in pathogenesis of the disease by mediating adherence and immune evasion. The aim of this study was sequencing Iranian M. synoviae isolates for the detection of nucleotide variation in the M. synoviae vlhA gene. Using oligonucleotide primers complementary to the single-copy conserved 5´ end...
