Background and Objectives Bordetella holmesii is associated with a pertussis-like respiratory syndrome in healthy individuals and also a rare cause of septicaemia, endocarditis, pneumonia, and septic arthritis, mostly in immunocompromised patients. Culture technique and real-time PCR are 2 methods used to detect Bordetella spp. Materials and Methods In this study, 435 nasopharyngeal specimens...

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...

The baboon model of Bordetella pertussis infection is the newest and most clinically accurate model of the human disease to date. However, among the 15 experimentally infected baboons in this study, a subset of baboons did not exhibit the expected high bacterial colonization levels or increase in white blood cell count. Moreover, cultures of nasopharyngeal wash samples from several baboons sugg...

AIMS To investigate the clinical picture and frequency of Bordetella pertussis and B parapertussis infections after introduction of acellular pertussis (acP) vaccines in Germany. METHODS Prospective surveillance for B pertussis and B parapertussis in 14 144 toddlers. Pertussis vaccination coverage was 86%, either with acP (75%) or whole cell pertussis (wcP) vaccine (11%). All children present...

Bordetella pertussis and Bordetella bronchiseptica are capable of obtaining iron from hemin and hemoglobin. Genes encoding a putative bacterial heme iron acquisition system (bhu, for Bordetella heme utilization) were identified in a B. pertussis genomic sequence database, and the corresponding DNA was isolated from a virulent strain of B. pertussis. A B. pertussis bhuR mutant, predicted to lack...

Real-time PCR assays based on the LightCycler technology were developed for individual (simplex PCR) and simultaneous (duplex PCR) detection and discrimination of Bordetella pertussis and Bordetella parapertussis in clinical samples. The assays were evaluated with 113 specimens from patients with and without symptoms of pertussis. Results were compared to those from conventional culture and Taq...
