The Culture of Bordetella pertussis

Survival of Bordetella pertussis in Tissue Culture of Animal Cells

Importance of culture in laboratory diagnosis of Bordetella pertussis infections.

Nasopharyngeal secretions from 223 patients were examined for the presence of Bordetella pertussis and B. parapertussis by culturing on Regan-Lowe agar (J. Regan and F. Lowe, J. Clin. Microbiol. 6:303-309, 1977) and by direct fluorescent-antibody testing. B. pertussis was found in 38 patients; B. parapertussis was recovered from 2. Culturing was more sensitive (38 of 38 patients) than direct fl...

Unexpected isolation of Bordetella pertussis from a blood culture.

Bordetella pertussis was isolated from a culture of blood from a 31-year-old man with Wegener's granulomatosis. The organism was detected with the BACTEC 9240 system after 6 days of incubation and was confirmed as B. pertussis by the Centers for Disease Control and Prevention. To our knowledge, this is the first published report of the recovery of B. pertussis from blood.

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...
