Survival of Bordetella pertussis in Tissue Culture of Animal Cells

Leukocytosis-promoting factor of Bordetella pertussis.

The leukocytosis-promoting factor (LPF), purified from materials extracted from agar in which Bordetella pertussis was grown, caused leukocytosis and an increased sensitivity to histamine when as little as 0.04 Ag of protein was given intravenously to mice. LPF was adsorbed onto erythrocytes, causing hemagglutination. As little as 0.03 ,g of LPF protein agglutinated chicken erythrocytes in 0.05...

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...

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.
