A novel method for the extraction of outer membrane vesicles (OMVs) from Bordetella pertussis Tohama strain

Iranian Journal of Microbiology, 2020
Background and Objectives: There are many pertussis outbreaks which is mainly due to the reduction in the immunity of acellular pertussis (aP) vaccines. Therefore, there is a crucial necessity to develop a new generation of pertussis vaccine.

Shared primer PCR combined with hybridisation for the detection of Bordetella Pertussis and B. Parapertussis [PDF]

, 2001
A method of detecting Bordetella pertussis and Bordetella parapertussis infection is provided. The method includes amplification of a Bordetella porin gene fragment from a sample such as a human nasopharyngeal aspirate using a Bordetella-specific primer,

Pertussis in the Association of Southeast Asian Nations: epidemiology and challenges

International Journal of Infectious Diseases, 2019
Pertussis is a highly infectious respiratory disease caused by Bordetella pertussis. Infants and young children are particularly at risk of severe and life-threatening disease. Infectious older individuals may transmit Bordetella pertussis to unprotected

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

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).

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 ...

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.

Detection of Protein–Protein Interactions in Escherichia coli With Single Molecule Sensitivity

Advanced Science, Volume 13, Issue 37, 3 July 2026.
This article describes a regulatory circuit in Escherichia coli able to detect protein–protein interactions with exquisite sensitivity. The interaction between two hybrid proteins fused to Bordetella pertussis adenylate cyclase and its activator calmodulin triggers a potent cyclic AMP signaling cascade.

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
