Regulation of pertussis toxin and lipopolysaccharide levels of Bordetella pertussis 134 in response to modulators
Whooping cough (pertussis) is a highly contagious disease of the human respiratory tract, which is caused by Bordetella pertussis. Reemerge of pertussis in some highly immunized populations and divergency in gene order among several B. pertussis strains promoted this research to study the change of pertussis toxin (PT) and lipopolysacharide levels in response to the different environments. Th...
متن کاملThe Impact of Early Postpartum Maternal Pertussis Vaccination on the Protection of Infants: A Randomized Clinical Trial
Background: Despite primary vaccination, infants under six months run a risk of infection with pertussis. Objective: To determine the impact of early postpartum maternal pertussis vaccination on protecting infants from the disease. Methods: All mothers (n=405) who gave birth to healthy term infants were educated on the cocoon strategy. The moth...
متن کاملVirulence Factors Variation Among Bordetella Pertussis Isolates in Iran
Pertussis is still endemic and the recently resurgence of the disease caused by Bordetella pertussis has been shown in many countries. The polymorphism of the virulence genes of B. pertussis and lack of any information about the allelic variation between the Iranian isolates promotes us to analysis of the genes encoded virulence factors including ptxS1, prn, fim3 and cya to understand the diffe...
متن کاملSeroprevalence of IgG Antibodies against Bordetella pertussis in Different Age Groups in Tehran, Iran
Background and Aims: Pertussis is a highly contagious, vaccine-preventable disease. Determination of the seroepidemiology of pertussis makes possible the evaluation of pertussis immunity in a population. In this study, we determined the seroprevalence of Bordetella pertussis IgG antibodies in different age groups in Tehran, Iran. Materials and Methods: Overa...
متن کاملAllelic variations between vaccine strains and circulating strains in pxtP of Bordetella pertussis in Iran
Introduction: Despite high level of vaccination against pertussis‚ whooping cough has re-emerged as a health threat, especially in infants. This could be related to expansion of Bordetella pertussis with novel alleles for virulence factors including the pertussis toxin promoter, ptxP3. Compared to ptxp1 strains‚ ptxp3 strains produce more pertussis toxin which results in immune supp...
متن کاملSerologic Evidence of Pertussis Infection in Vaccinated Iranian Children
Background: It seems that the incidence of pertussis-like illnesses is considerably increasing despite the wide coverage of immunization with the whole cell pertussis vaccine. We aimed to investigate the occurrence of pertussis in vaccinated children by measuring anti-pertussis antibodies. Methods: In this cross-sectional study, blood samples were taken from vaccinated children aged 2, ...
