Viability of Bordetella pertussis was preserved when glycerol broth suspensions were quick frozen and stored at -70 C for as long as 45 months.

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...

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...

Bordetella 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...
