Antigenic analysis of Bordetella pertussis filamentous hemagglutinin with phage display libraries and rabbit anti-filamentous hemagglutinin polyclonal antibodies.
Although substantial advancements have been made in the development of efficacious acellular vaccines against Bordetella pertussis, continued progress requires better understanding of the antigenic makeup of B. pertussis virulence factors, including filamentous hemagglutinin (FHA). To identify antigenic regions of FHA, phage display libraries constructed by using random fragments of the 10-kbp ...
متن کاملSubcutaneous administration of a fusion protein composed of pertussis toxin and filamentous hemagglutinin from Bordetella pertussis induces mucosal and systemic immune responses
Objective(s): After decades of containment, pertussis disease, caused by Bordetella pertussis seems to be re-emerging and still remains a major cause of reported vaccine-preventable deaths worldwide. The current licensed whole-cell vaccines display reactogenicity while acellular vaccines are expensive and do not induce Th1-type immune responses that are required for optimum protection against t...
متن کاملMucosal immunization with filamentous hemagglutinin protects against Bordetella pertussis respiratory infection.
Mucosal immunization of mice with purified Bordetella pertussis filamentous hemagglutinin (FHA), by either the respiratory or the gut route, was found to protect against B. pertussis infection of the trachea and lungs. Intranasal immunization of BALB/c and (C57BL/6 x C3H/HeN)F1 adult female mice with FHA prior to B. pertussis aerosol challenge resulted in a 2 to 3 log reduction in number of bac...
متن کاملexpression, purification and characterization of three overlapping immunodominant recombinant fragments from bordetella pertussis filamentous hemagglutinin
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...
متن کاملCloning, partial sequence, expression, and antigenic analysis of the filamentous hemagglutinin gene of Bordetella pertussis.
The gene coding for the filamentous hemagglutinin (FHA), one of the main factors involved in mediating adherence of Bordetella pertussis to ciliated host cells, was cloned in Escherichia coli, and the 3,500-base-pair nucleotide sequence encoding the amino-terminal region was determined. Molecular cloning, together with the characterization of recombinant FHA-related proteins produced in E. coli...
