Evaluation of PCR for Diagnosis of Bordetella pertussis and Bordetella parapertussis Infections [PDF]

Journal of Clinical Microbiology, 1998
ABSTRACT PCR, using primers PIp1 and PIp2, was evaluated for the detection of DNA from Bordetella pertussis in bacterial strains and in nasopharyngeal samples from patients with a cough lasting at least 7 days. The assay could detect DNA from 6 CFU of B.

CLINICAL CASE REPORT: PERTUSSIS INFECTION FOLLOWED BY A PARAPERTUSSIS INFECTION IN THE SAME CHILD

Problems of Infectious and Parasitic Diseases
Whooping cough is a vaccine-preventable, acute respiratory disease caused by the gram-negative bacterium Bordetella pertussis. In recent years there has been a worldwide reccurrence of pertussis infection.

From Lake Victoria to the Tap: Antibiotic Resistance and Pathogenic Contamination of Kisumu City Water Supply and Wastewater Network

Tropical Medicine &International Health, Volume 31, Issue 4, Page 547-559, April 2026.
ABSTRACT Waterborne diseases and antimicrobial resistance (AMR) pose mounting public health threats across sub‐Saharan Africa, particularly in rapidly urbanising regions dependent on untreated or poorly treated surface waters. This study applied shotgun metagenomic sequencing to characterise microbial communities, virulence factors and antibiotic ...

Incidence of RSV‐ and Influenza‐Associated Hospitalizations With Community‐Acquired Pneumonia and Other Acute Respiratory Infection Among Adults in Japan in 2022–2024: APSG‐J2 Study

Influenza and Other Respiratory Viruses, Volume 20, Issue 3, March 2026.
ABSTRACT Background Quantifying the burden of respiratory syncytial virus (RSV) in adults is challenging compared to influenza, and data among older adults remain scarce in Japan. Country‐specific evidence is essential to support RSV vaccination policy.

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.

Torque Teno Virus Levels During Viral Respiratory Infections: The Interplay With Immune Dysregulation and Coagulopathy Biomarkers

Journal of Medical Virology, Volume 98, Issue 2, February 2026.
ABSTRACT Torque teno virus (TTV) is a ubiquitous, nonenveloped DNA virus of the Anelloviridae family and a proposed surrogate marker of immune competence. Although nonpathogenic, its replication reflects host immune status and is associated with immune dysregulation during respiratory viral infections (RVIs).

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.

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).
