Differential and Temporal Immunomodulation of alpha4 Integrins on CD4+ Memory Cells by Bordetella pertussis and Bordetella parapertussis [PDF]

, 2012
Pertussis, caused by Bordetella pertussis (B. pertussis), is reemerging worldwide due to vaccine inefficacy. The hallmarks of infection are extreme lymphocytosis and delayed recovery, which are partially associated with pertussis toxin.

Swedish Infants Developed Pertussis at a Younger Age if Their Mother Was the Possible Source of Infection in 2009–2015

Acta Paediatrica, EarlyView.
ABSTRACT Aim The aim of this study was to investigate the possible source of laboratory‐confirmed pertussis in infants under 6 months of age. Methods This nationwide prospective study was based on laboratory‐confirmed cases reported in the enhanced pertussis surveillance in Sweden from 2009 to 2015. The parents or carers of 345 infants were interviewed

Seroprevalence of IgA and IgM antibodies to Bordetella pertussis in healthy Japanese donors: Assessment for the serological diagnosis of pertussis.

PLoS ONE, 2019
Pertussis is a human respiratory infection caused by the gram-negative bacterium, Bordetella pertussis. To evaluate the pertussis burden and vaccine efficacy, diagnosis and epidemiological surveillance should be based on accurate and valid diagnostic ...

Comparison of Bordetella species identification among differing rt-PCR assays in the United States

Microbiology Spectrum
In the United States, the general laboratory method for diagnosing pertussis, caused by Bordetella pertussis, is real-time PCR (rt-PCR) targeting insertion sequence 481 (IS481).

Laboratory-based surveillance of pertussis using multitarget real-time PCR in Japan: evidence for Bordetella pertussis infection in preteens and teens

New Microbes and New Infections, 2015
Between January 2013 and December 2014, we conducted laboratory-based surveillance of pertussis using multitarget real-time PCR, which discriminates among Bordetella pertussis, Bordetella parapertussis, Bordetella holmesii and Mycoplasma pneumoniae.

Blockade of the Adenylate Cyclase Toxin Synergizes with Opsonizing Antibodies to Protect Mice against Bordetella pertussis

mBio, 2022
Bordetella produces an array of virulence factors, including the adenylate cyclase toxin (ACT), which is essential, immunogenic in humans, and highly conserved.

The Eukaryotic Host Factor 14-3-3 Inactivates Adenylate Cyclase Toxins of Bordetella bronchiseptica and B. parapertussis, but Not B. pertussis

mBio, 2018
Bordetella pertussis, Bordetella bronchiseptica, and Bordetella parapertussis share highly homologous virulence factors and commonly cause respiratory infections in mammals; however, their host specificities and disease severities differ, and the reasons

isolates in Finland: Serotype and fimbrial expression [PDF]

, 2008
Background Bordetella pertussis causes whooping cough or pertussis in humans. It produces several virulence factors, of which the fimbriae are considered adhesins and elicit immune responses in the host. B.

Tissue Resident Memory Cells: Friend or Foe?

Immunology, EarlyView.
Tissue‐resident memory T cells (TRM cells) are specialised immune cells in barrier tissues like the lungs, skin and gut, providing rapid host defence and tumour surveillance. Their retention and differentiation are regulated by molecules such as CD69, CD103 and TGF‐β. Dysregulation of TRM cells can lead to chronic activation, driving conditions such as
