Bordetella parapertussis and Bordetella bronchiseptica contain transcriptionally silent pertussis toxin genes [PDF]
Journal of Bacteriology, 1987 Pertussis toxin, the major virulence factor of Bordetella pertussis, is not produced by the closely related species Bordetella parapertussis and Bordetella bronchiseptica. It is shown here that these two species possess but do not express the complete toxin operon.

Increase in pertussis cases along with high prevalence of two emerging genotypes of Bordetella pertussis in Perú, 2012 [PDF]
, 2016 As has occurred in many regions worldwide, in 2012 the incidence of pertussis increased in Perú. This epidemiologic situation has been associated with a waning vaccine-induced immunity and the adaptation of Bordetella pertussis to vaccine-induced ...

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.

Evaluation of real-time PCR for diagnosis of Bordetella pertussis infection [PDF]
, 2006 Background Nucleic acid amplification of the IS481 region by PCR is more sensitive than culture for detection and diagnosis of Bordetella pertussis but the assay has known cross-reactivity for Bordetella holmesii and its use as a routine diagnostic assay

Frontiers in Cellular and Infection Microbiology, 2021 The Bordetella genus is divided into two groups: classical and non-classical. Bordetella pertussis, Bordetella bronchiseptica and Bordetella parapertussis are known as classical bordetellae, a group of important human pathogens causing whooping cough or ...

Membrane vesicles derived from Bordetella bronchiseptica: Active constituent of a new vaccine against infections caused by this pathogen [PDF]
, 2018 Bordetella bronchiseptica, a Gram-negative bacterium, causes chronic respiratory tract infections in a wide variety of mammalian hosts, including humans (albeit rarely).

PLoS ONE, 2009 Although the prevalence of Bordetella parapertussis varies dramatically among studies in different populations with different vaccination regimens, there is broad agreement that whooping cough vaccines, composed only of B.

Patterns of Bordetella parapertussis Respiratory Illnesses: 2008-2010 [PDF]
Clinical Infectious Diseases, 2011 Clinical specimens from 9 states during 2008-2010 were tested by PCR for Bordetella pertussis and Bordetella parapertussis. Of the positive samples, 13.99% were identified as B. parapertussis. It was concluded that B. parapertussis infections are more common than previously realized and contribute to cases thought to be vaccine failures.

O Antigen Protects Bordetella parapertussis from Complement [PDF]
Infection and Immunity, 2008 ABSTRACT Bordetella pertussis , a causative agent of whooping cough, expresses BrkA, which confers serum resistance, but the closely related human pathogen that also causes whooping cough, Bordetella parapertussis , does not. Interestingly, B. parapertussis , but not

Molecular evolution of the two-component system BvgAS involved in virulence regulation in Bordetella. [PDF]
PLoS ONE, 2009 The whooping cough agent Bordetella pertussis is closely related to Bordetella bronchiseptica, which is responsible for chronic respiratory infections in various mammals and is occasionally found in humans, and to Bordetella parapertussis, one lineage of
