Isolation of Bordetella pertussis from swabs.

Isolation of Bordetella pertussis from swabs.

Four varieties of swabs held in plastic containers and three swab transport media kits, all obtainable in the United Kingdom, were tested to assess their effectiveness in the isolation of Bordetella pertussis. The highest isolation rates up to 48 hours were obtained with Dacron swabs held in plastic containers. Swab-transport media kits proved unsatisfactory. B pertussis may have a stronger aff...

Recovery of Bordetella pertussis from nasopharyngeal swabs.

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.

Selective medium for the isolation of bordetella pertussis and parapertussis.

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...
