Mucosal 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 کاملEVALUATION OF SERUM OPSONIC CAPACITY AGAINST BORDETELLA PERTUSSIS BY CHEMILUMINESCENCE
Serum opsonic capacity against B. pertussis was studied by using quantitative chemiluminescence (CL), a method known to have several advantages over conventional methods in evaluating opsonization and phagocytosis. Sera from unvaccinated infants was shown not to contain opsonins against B. pertussis and in unvaccinated infants suffering from whooping cough, no opsonins were detected. In ad...
متن کاملProtection of mice against viral infection by Corynebacterium parvum and Bordetella pertussis.
Mice could be significantly protected against infection with herpes simplex virus (HSV) by i.p. or i.v. injection of killed Corynebacterium parvum 7 days before infection. This protection was seen in inbred strains of mice with a different degree of sensitivity to HSV and after both i.p. and i.v. infection. Resistant mice immunosuppressed by X-irradiation and showing an increased susceptibility...
متن کاملImmunization status of Iranian military recruits against Bordetella pertussis infection (whooping cough).
INTRODUCTION Military recruits are susceptible to respiratory pathogens because of increased antibiotic resistance and the lack of an effective vaccine. The goal of the current study was to determine the immunological status of the Bordetella pertussis among conscripts in Iranian military garrisons. METHODOLOGY The study population consisted of 424 conscripts aged 18 to 21 years who enrolled ...
متن کاملBordetella pertussis Infection or Vaccination Substantially Protects Mice against B. bronchiseptica Infection
Although B. bronchiseptica efficiently infects a wide range of mammalian hosts and efficiently spreads among them, it is rarely observed in humans. In contrast to the many other hosts of B. bronchiseptica, humans are host to the apparently specialized pathogen B. pertussis, the great majority having immunity due to vaccination, infection or both. Here we explore whether immunity to B. pertussis...
