Bordetella pertussis and pertussis vaccines.
Bordetella pertussis is a human-specific pathogen that causes whooping cough. The use of pertussis whole-cell vaccines in infants and toddlers led to decreased circulation of the bacterium in the child population and a marked decrease in the incidence of the disease. However, vaccine does not result in life-long immunity; indeed, the circulation of the bacterium has not been controlled in the a...
متن کاملBordetella pertussis Isolates, Finland
To the Editor: Pertussis, or whooping cough, is a highly contagious respiratory disease in humans caused by Bordetella pertussis. Reemergence of pertussis has been observed in many countries with high vaccination coverage. In the United States, reported cases of pertussis in adolescents and adults have increased since the 1980s, despite increasingly high rates of vaccination in infants and chil...
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 کاملBordetella pertussis polymorphism and pertussis vaccines.
The topic of the article by Bottero et al. (1) is an important one, a bacterial vaccine for a preventable disease, pertussis. Many articles have been published on the subject in the last 10 years (for a review, see reference 6). In their study, Bottero et al. neither followed the recommendations of consensus meetings nor used published nomenclature. Furthermore, they compared vaccines that cann...
متن کاملRegulation 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...
