The aim of this study was to construct, expression of a novel recombinant chimeric protein consisting of Pyruvate dehydrogenase beta subunit (PDHB) and high antigenic region of integral membrane lipoprotein P80 of Mycoplasma agalactiae as a potential diagnostic tool. The full-length sequence of pdhb and a portion of antigenic regions of P80 were selected and analyzed by CLC ma...

definitive hosts of the echinococcus granulosus (e. granulosus ) parasite are carnivores such as dogs,wolves and foxes. detection of this parasite through faecal examination is not possible. in this study, dotblotting test for e. granulosus -specific coproantigens has been evaluated in dog. three 2–3-month-old puppies were treated with piperazine and then faecal samples were collected as pre-in...

Neisseria meningitidis is a major causative agent of bacterial septicemia and meningitis in humans. Currently, there are no vaccines to prevent disease caused by strains of N.meningitidis serogroup B. The Class 1 Outer Membrane Protein (OMP) has been named porA which is a cation selective transmembrane protein of 45 KDa that forms trimeric pore in the meningococcal outer membrane. PorA from ser...

Background and Aims: Influenza A virus of Orthomyxoviridae family is able to create pandemic influenza. Vaccination is the most effective way to prevent influenza virus infection. Matrix protein 2 (M2) is a homotetramer ion channel with 97 amino acids length and highly conserved among influenza viruses and is considered for development of a universal influenza vaccine. Materials and Methods: We...

background: filamentous hemagglutinin (fha) is one of the most important immunoprotective antigens of bordetella pertussis (b.pertussis) and a major component of the acellular pertussis vaccine. in the present study, three overlapping recombinant fragments from the immunodominant region of fha were produced and their immunogenicity was investigated. methods: three overlapping coding sequences o...

the objective of this study was to determine the protein pattern and antigenic structure of bhv-1. ten viral isolates from cows with clinical signs of respiratory infections were selected for this study and confirmed by sn test. all samples were cultured on cell cultures and purified by ultracentrifugation. purified isolates were electerophorsed using sds-page method and immunoblotted. viral an...
